i
INFO
Indicates useful supplemental information.
Please read these instructions before installing or operating the unit to prevent personal
injury or damage to the unit.
1.2 SAFETY INSTRUCTIONS - GENERAL
1.2.1 Installation and wiring compliance
• Installation and wiring must comply with the Local and National Electrical Codes and
must be done by a certied electrician.
• Wrong installation on a boat may lead to corrosion of the boat. It is recommended
that the installation on a boat may be carried by a boat electrician.
• If an extension cord is used to feed 120 VAC power, please ensure that it has 3-pin
grounding, NEMA5-15 plug / receptacle and wire size is the same as the wire size of
the power cord (see wire sizes in the specications at Section 7).
1.2.2 Preventing electrical shock
• The metal chassis of the charger is connected to the Ground pin of the power cord
plug. For proper grounding of the metal chassis, ensure that Ground pin of the AC
outlet powering the charger is rmly connected to the System / Earth Ground.
• Disassembly / repair should be carried out by qualied personnel only.
• Disconnect all AC and DC side connections before working on any circuits associated with
the unit. Turning off AC input to the unit may not entirely remove dangerous voltages.
• Be careful when touching bare terminals of capacitors. Capacitors may retain high le-
thal voltages even after the power has been removed. Discharge the capacitors before
working on the circuits.
• Do not operate the charger if the AC power cord is damaged.
4 | SAMLEX AMERICA INC.
1.2.3 Installation environment
• The charger should be installed indoor only in a well ventilated, cool, dry environment.
• Do not expose to moisture, rain, snow or liquids of any type. When installed in a boat,
ensure that it is not subject to water spray / bilge water splash.
• Do not mount the charger directly above or below the battery being charged because
gases / electrolyte from the battery will corrode / damage the charger. Do not install in
the same compartment as batteries.
• To reduce the risk of overheating and re, do not obstruct the suction and discharge
openings of the cooling fan.
• To ensure proper ventilation, do not install in a low clearance compartment that has
restricted cool air change. There should be at 6" clearance all around the unit.
1.2.4 Preventing re and explosion hazards
• Working with the unit may produce arcs or sparks. Thus, the unit should not be used
in areas where there are ammable materials or gases requiring ignition protected
equipment. These areas may include spaces containing gasoline-powered machinery,
fuel tanks, and battery compartments.
1.2.5 Precautions when working with batteries
• Charge Lead Acid Batteries only
• Never charge a frozen battery – it may explode!
• Batteries contain very corrosive diluted Sulphuric Acid as electrolyte. Precautions
should be taken to prevent contact with skin, eyes or clothing.
• Batteries generate Hydrogen and Oxygen during charging resulting in evolution of
explosive gas mixture. Care should be taken to ventilate the battery area and follow
the battery manufacturer’s recommendations.
• Never smoke or allow a spark or ame near the batteries.
• Use caution to reduce the risk of dropping a metal tool on the battery. It could spark
or short circuit the battery or other electrical parts and could cause an explosion.
• Remove metal items like rings, bracelets and watches when working with batteries.
The batteries can produce a short circuit current high enough to weld a ring or the
like to metal and, thus, cause a severe burn.
• If you need to remove a battery, always remove the ground terminal from the battery
rst. Make sure that all the accessories are off so that you do not cause a spark.
• Disconnect the AC input power to the charger before connecting / disconnecting the
batteries or other DC loads or when working on the charger
• Disconnect the AC input power before changing setting of the DIP Switch

SECTION 3 | Description, Features & Cooling
3.1 DESCRIPTION
These chargers are used to charge Lead Acid Batteries (Flooded, AGM or Gel Cell). SEC-
1215UL (Maximum charging current 15A) and SEC-1230UL (Maximum charging current
30A) are used to charge 12 V batteries. SEC-2415UL (Maximum charging current 15A) is
used to charge 24 V batteries. These chargers can be powered from AC power source of
either 120 V, 60 Hz (Pre-set) or 230 V, 50 Hz (By changing jumper position inside the unit -
See Section 5.2.1 for instructions).
3.2 FEATURES
• State of the art switched mode technology is used for very high efciency, lightweight
and quiet operation.
• User selectable AC input voltage - 120 V , 60 Hz (Pre-set) or 230 V , 50 Hz
[By changing jumper position inside the unit (See Section 5.2.1 for instructions)].
• User selectable 2 or 3 stage charging algorithm ensures rapid and safe charging of all
types of lead acid batteries - Flooded, AGM, Gel Cell or batteries with external load.
(Through externally accessible DIP Switches - see Section 5, Tables 5.1 and 5.2 for
instructions)
• Fully automatic "Connect and Forget" operation
• 3 banks of batteries can be charged simultaneously without use of an external battery
isolator
• Monitoring through ON status LED and Ammeter
• Temperature controlled cooling fan (SEC-1230UL, SEC-2415UL)
• Protections against short circuit, over current, reverse battery connection and over
temperature (over temperature for SEC-1230UL and SEC-2415UL)
• Can be used as a power supply or as a DC UPS (Uninterruptible DC Power Supply)
when used with a battery (DIP Switch set at "Battery with load" - See Section 5,
Tables 5.1 and 5.2 for instructions)
3.3 COOLING
SEC-1215UL is cooled by convection and does not have any thermal overload shut down.
SEC-1230UL and SEC-2415UL are cooled by convection and in addition, have a tempera-
ture controlled fan for forced air cooling. Two temperature sensors mounted on the
power transformer control the switching of the fan and over temperature shut down.
The fan will be switched on by the rst temperature sensor when the power transform-
er reaches 60°C / 140°F.
Hence, at lower loads, the fan may not cut in and will be off. This is normal.
In case the fan fails or if the cooling is not adequate, the second temperature sensor will
shut down the unit if the power transformer reaches 105°C / 221°F. The red LED will switch
OFF. The unit will automatically recover on removal of thermal overload condition.

SECTION 4 | Charging States & Protections
4.1 CHARGING STAGES
i
INFO
a) VOLTAGE READINGS ON NO LOAD
The output has one common Negative terminal and three Positive terminals
for charging 3 banks of batteries. Each Positive terminal has an internal
isolating diode in series which has a forward voltage drop of 0.8 to 1.1 V. On
no load (that is when no battery or other DC load is connected to any of the 3
terminals) , the voltage reading will read 0.8 to 1.1 V higher than the specied
oat voltage. Note that the specied oat voltage is at a load of 1 A. Also,
the voltage on the terminals not connected to the load (for example, when
one bank of battery is connected to one Positive terminal, the other 2 Positive
terminals will remain disconnected) will read 0.8 to 1.1 Volt higher than the
voltage of the loaded terminal.
b) VOLTAGE SPECIFICATIONS
All rated voltages are specied at battery temperature of 80°F.
These chargers can be manually selected to operate in 3 stage or 2 stage modes (Please
see "Selecting the Type of Battery and Charging Stages" at Section 5.2.2). The charging
stages are described below:
4.1.1 Stage 1 - Constant Current or Bulk Charge Stage
When the battery is low, it will try to draw larger charging current. The charger senses
the current draw and limits this to the maximum permissible value (15A for SEC-1215UL /
SEC-2415UL and 30A for SEC-1230UL). Bulk charging takes place at this constant current.
In this condition of constant current, the voltage measured at the charger or battery
terminals will be the battery's own intrinsic voltage proportional to its state of charge.
The constant current injected into the battery starts restoring the battery capacity and it's
voltage starts rising. When this voltage approaches the threshold of battery "gassing",
termed "Boost or Absorption Voltage", the charger automatically switches over to Stage 2
- "Boost or Absorption Stage". The value of this voltage depends upon the type of battery
being charged (See DIP Switch Settings in Section 5, Tables 5.1 and 5.2). By this time,
approximately 80% of the battery capacity will normally have been restored (Note: The
percentage capacity restored till the point the battery reaches the Boost or Absorption
Voltage is inversely proportional to the value of the bulk charge current).
4.1.2 Stage 2 - Constant Voltage Boost or Absorption Stage
As explained at Section 4.1.1, when the battery voltage approaches the point where
battery "gassing" can begin, the charger automatically switches over to the "Boost or
Absorption Stage". The charger applies a constant voltage whose value depends upon
the type of battery selected (See DIP Switch Settings in Section 5, Table 5.1 and 5.2). This
controlled overcharge restores the balance 20% of the capacity in a minimum amount of
time. As the capacity is fully restored, the charging current starts reducing. When the cur-
rent reduces below the preset threshold (1.5 to 2A for SEC-1215UL / 2415UL and 2.5 to 3A
for SEC-1230UL), the charger automatically switches to the "Float or Maintenance Stage".
10 | SAMLEX AMERICA INC.
SECTION 4 | Charging States & Protections
4.1.3 Stage 3 - Constant Voltage , Float or Maintenance Charging Stage
As explained at Section 4.1.2, as the charging current drops below the preset threshold
(1.5 to 2 amps for SEC-1215UL / SEC-2415UL and 2.5 A to 3 A for SEC-1230UL), it signals
that the battery is 100% charged.
In this "Float or Maintenance Charging Stage", the charger outputs a constant volt-
age of 13.5 V for 12 V system and 27 V for 24 V system. This helps in maintaining 100%
capacity of the battery and also compensates for self discharge. The battery can remain
connected in this stage indenitely without the risk of overcharging or excessive loss of
electrolyte. In Float Stage, the battery will consume around 0.1% of its Ah capacity to
compensate for self discharge.
!
CAUTION!
3 stage charging is recommended for charging stand-alone, unloaded batteries
(there is no load connected to the battery when it is being charged).
If a load is also connected simultaneously, a part of the charger's output current
will be diverted to this load. Thus, the charger may remain locked in the "Boost
or Absorption Mode" if the current drawn by the load is more than the preset
value of threshold current determining change over between the Boost and Float
Stages (1.5 to 2A for SEC-1215UL / 2415UL and 2.5 to 3A for SEC-1230UL). This
will lead to overcharging and loss of electrolyte.
For charging a battery when a load is also connected simultaneously, the "Boost
or Absorption Stage" is required to be disabled. Select "Battery with Load" using
the DIP switch. See details under "Powering other DC Loads" at Section 5.4.1.
4.2 PROTECTIONS
4.2.1 Short Circuit Shut Down
In case of a short circuit on the output side, the charger will shut down. The Red LED (2 in
Figs 2.1 to 2.3) will switch off. The charger will automatically recover once the short circuit
condition is removed.
4.2.2 Over load Current Limiting
The current drawn by the battery / load is automatically limited to a maximum of 15 A
for SEC-1215UL / SEC-2415UL and 30A for SEC-1230UL. If the battery / load tries to draw
a higher current than these limits, the output voltage of the unit will start to drop.
If a battery is connected, the output voltage will be clamped to the actual battery volt-
age proportional to its state of charge. The unit will automatically recover when the
overload condition is removed.
4.2.3 Reverse Battery Connection Cut Off
The output is internally fused on the DC side (20A for SEC-1215UL / SEC-2415UL and 40A
for SEC-1230UL). In case, the polarity of the battery connection is reversed, the fuse(s)
will blow . The Red LED (2 in Figs 2.1 to 2.3) will switch off. The fuse(s) will be required
to be replaced for the unit to function again.
10 | SAMLEX AMERICA INC. SAMLEX AMERICA INC. | 11
SECTION 4 | Charging States & Protections
4.2.4 Thermal Overload Shutdown
SEC-1215UL is cooled by convection and does not have any thermal overload shut down.
SEC-1230UL and SEC-2415UL are cooled by convection and in addition, have a tempera-
ture controlled fan (9 in Figs 2.2 and 2.3) for forced air cooling. Two temperature sensors
mounted on the power transformer control the switching of the fan and over tempera-
ture shut down. The fan will be switched on by the rst temperature sensor when the
power transformer reaches 60°C / 140°F. Hence, at lower loads, the fan may not cut in
and will be off. This is normal.
In case the fan fails or if the cooling is not adequate, the second temperature sensor will
shut down the unit if the power transformer reaches 105°C / 221°C. The Red LED will
switch off. The unit will automatically recover on removal of thermal overload condition.
!
CAUTION!
Keep the charger in a well ventilated, cool and open area. Do not block the
vent holes on the sides or the discharge openings of the cooling fan.

5.2 CHARGER OPERATION
5.2.1 Preparing the Charger for Operation: Selecting AC input voltage
The charger is pre-set to operate from input AC voltage of 120 VAC, 50 / 60 Hz.
To operate the charger from AC input voltage of 230 VAC, 50 / 60 Hz, change the inter-
nal setting as follows:
1. Remove the 4 screws on the Ammeter side of the top cover
2. Gently slide the top cover out by 2 to 3 inches. (CAUTION! The top cover will be re-
strained from fully sliding out by the wires connecting the Ammeter, LED and the fan)
3. Locate the jumper wire with a "Quick Female Disconnect". In the pre-set condition,
it is connected to the male vertical pin marked "115 V". Pull this female disconnect
upwards to disconnect from the "115 V" position. Connect this to the male vertical
pin marked "230 V"
4. Replace the fuse with the fuse recommended for 230 VAC operation (See fuse rat-
ing at Section 7)
5. Replace the AC plug of the power cord with a suitable 3 pin grounded plug to
mate with the 230 VAC outlet. CAUTION: The new plug should have 3 poles i.e.
Line (L) , Neutral(N) and Earth ground. Color code for the power cord conductors is:
- Line (L) - Black
- Neutral (N) - White
- Earth ground - Green
5.2.2 Preparing the Charger for Operation: Selecting the Type of Battery and
Charging Stages
The Float Voltage and Boost Voltage (Also called Absorption or Overcharge Voltage)
of different types of Lead Acid Batteries are different. Also, when a charger is used
to charge a battery and simultaneously supply a load , the Boost Stage is required to
12 | SAMLEX AMERICA INC. SAMLEX AMERICA INC. | 13
SECTION 5 | Installation & Charger Operation
be disabled to prevent overcharging of the battery (see details under
!
CAUTION!
at Section 4.1.3). A DIP Switch (4 in Figs 2.1 to 2.3) is provided on top of the output
terminals for selecting the battery type and for disabling the Boost Stage when charging
loaded batteries. The following selections can be made with the help of the DIP Switch.
!
CAUTION!
Do not change the DIP Switch setting when the charger is operating. Always
change the DIP Switch setting when the charger is off , i.e. after disconnecting
the charger from the AC input power.
NOTE: The voltages are for a temperature of 80°F.

5.2.3 Connecting The Batteries or Other DC Loads
The output has a common Negative (-) terminal (5 in Figs 2.1 to 2.3) and 3 Positive
terminals (6, 7 and 8 in Figs 2.1 to 2.3) for charging up to 3 independent banks of
batteries. Each Positive connector has it's own internal isolating diode which works as a
battery isolator. If more than one bank of batteries is connected, these will be charged
at the same time as long as the AC power is available to the charger (the maximum
charging current of 15 A of SEC-1215UL / SEC-2415UL and 30 A of SEC-1230UL will be
shared among the connected banks of the batteries depending upon their discharged
states). In case the AC power fails or if there is no output from the charger, the isolating
diodes will prevent charging / discharging among the batteries connected to the banks.
The above arrangement works as a battery isolator and can divide the charging current
into a maximum of 3 isolated branches and allows current ow in each branch in one
direction only. If more than one battery systems are being used independently, the system
batteries will discharge to different levels. If system batteries are connected in parallel
to charge from a single charger, a weak or a dead battery will drain the charge from the
strong battery. Such situation occurs in RVs, boats and other vehicles where 2 separate
battery systems are used – starter battery for starting and running the engine and the
other auxiliary / house battery system for running auxiliary devices like inverters, refrigera-
tors, car stereos etc. Here, the starter battery should be connected to one bank and the
auxiliary / house battery to the second bank. Fig. 5.1 shows this connection.
In a single battery bank, two or more batteries may be connected in parallel to increase
their Ampere Hour (Ah) capacity. These will be discharged and charged as a single battery
bank. In this case, the paralleled bank of multiple batteries is to be considered as a single
bank and connected to any one of the 3 banks of the charger as shown in Fig. 5.2 for bank
of 4 batteries. For proper charging of all the batteries, please ensure that the Positive wire
“A” from the charger is connected to the Positive terminal of the rst battery (Battery 1)
and the Negative wire “B” is connected to the Negative terminal of the last battery (Bat-
tery 4). This will ensure the following:
• Resistance of the interconnecting cables will be balanced and the individual batteries
will see the same series resistance
• All the individual batteries will be charged at the same charging current and thus, will
be charged to the same state of charge
• None of the batteries will see an overcharge condition
When connecting a single battery or other single DC load, it can be connected to the com-
mon Negative and any one of the 3 Positive terminals as in Fig. 5.2.
5.3 OPERATION
When the charger is switched on, the Red LED marked "Power" (2 in Figs 2.1 to 2.3)
lights up indicating that output voltage is available. When the batteries are being
charged or when the charger is supplying other DC load, the current fed by the charger
will be indicated by the Ammeter (1, Figs 2.1 to 2.3).
SECTION 5 | Installation & Charger Operation
14 | SAMLEX AMERICA INC. SAMLEX AMERICA INC. | 15
SECTION 5 | Installation & Charger Operation
When the batteries are discharged, they will draw charging current proportional to
their discharged condition (up to the maximum current rating of the charger) and this
current draw will be shown by the Ammeter. When the batteries are fully charged, they
will draw very low current (may not be registered by the Ammeter) to compensate for
their self discharge.

5.3.1 Charging a Battery Installed in a Vehicle
Follow these steps when the battery is installed in a vehicle. A spark near a battery may
cause battery explosion. For safety and to reduce the risk of spark near the battery:
a) Position AC and DC cords to reduce risk of damage by hood, door or moving engine
parts
b) Stay clear of fan blades, belts, pulleys and other parts that can cause injury to persons
c) Check the polarity of the battery posts. A Positive (Pos, P, +) battery post usually has a
larger diameter than a Negative (Neg, N, -) post
d) Determine which post of the battery is grounded (Connected to the chassis Engine
Block). If the Negative post is grounded to the Engine Block (As in most vehicles), see
sub paragraph (e). If the Positive post is grounded, see sub paragraph (f).
e) For a Negative grounded vehicle, connect the Positive (Red) DC wire from the charger
to the Positive of the battery post. Connect the Negative (Black) DC wire from the
charger to a section of heavy gauge metal part of the frame or engine block which is
away from battery. Do not connect to carburetor, fuel lines or sheet metal body parts.
f) For a Positive grounded vehicle, connect the Negative (black) DC wire from the charg-
er to the Negative of the battery post. Connect the Positive (red) DC wire from the
charger to a section of heavy gauge metal part of the frame or engine block which is
away from battery. Do not connect to carburetor, fuel lines or sheet metal body parts.
g) Connect the charger AC power cord to the AC outlet

SECTION 5 | Installation & Charger Operation
h) When disconnecting the charger, turn switches to off, disconnect AC power cord,
remove connection from the vehicle chassis and then remove connection from the
battery terminal
5.3.2 Charging a Battery outside the Vehicle
Follow these steps when the battery is outside the vehicle. A spark near the battery may
cause battery explosion. For safety and to reduce risk of spark near the battery, connect
the charger as follows:
a) Check the polarity of the battery posts. A Positive (Pos, P, +) battery post usually has a
larger diameter than a Negative (Neg, N, -) post
b) Attach a piece of at least 3" of AWG #6 insulated battery wire to the Negative
battery post
c) Connect the Positive (Red) DC wire from the charger to the Positive battery post
d) Position yourself and the free end of the piece of wire attached to the Negative post
as far away from the battery as possible and then connect the Negative (Black) DC
wire from the charger to the free end of the piece of wire attached to the Negative
battery post
e) Do not face the battery when making the nal connection
f) Connect the charger AC power cord to the AC outlet
g) When disconnecting the charger, always do so in reverse sequence of connecting
procedure and break the rst connection while standing as far away from the
battery as practical
5.4 CHARGING MORE THAN ONE BANK OF BATTERIES
!
CAUTION!
When charging more than one bank of batteries at the same time using 3
Stage Charging, ensure that the batteries in the banks are in a similar discharged
condition. If one bank is completely discharged and another is almost fully
charged, the bank that is fully charged will be subjected to over charge condi-
tion during the time when the charger remains in Boost Stage for charging the
completely discharged bank. If batteries are in dissimilar states of charge, select
DIP Switch setting for "Battery with Load" (see Tables 5.1 and 5.2).
5.4.1 Powering Other DC Loads
The charger can be used as a power supply or as a DC UPS . For both these applications,
rst set the DIP Switch to "Battery with load" (See under " Selecting the Type of Battery
and Charging Stages" at Section 5.2.2).
To use as a power supply, rst switch off the DC load. Connect the DC load between
the common Negative terminal and one of the three Positive terminals. Ensure that the
maximum current drawn by the DC load is below the maximum current rating of the
charger. Switch on the charger and then the DC load.

In a DC UPS (Un-interruptible Power Supply) , the charger simultaneously powers the DC
load as well as the battery. As long as the AC power to the charger is available and the
charger is working normally, the charger will supply the DC load as well as charge/oat
the battery. In case the AC power fails or if the charger stops working, the battery will
automatically power the DC load. As soon as the AC power to the charger is restored ,
the DC load will once again be fed by the charger and at the same time the battery will
be recharged.
!
CAUTION!
Please ensure that the sum of the current drawn by the DC load and the current
desired for charging the battery is less than the maximum current capacity of
the charger.
To use as a DC UPS, rst switch off the DC load and connect it to the battery. Now
connect the battery as explained under "Charging a Battery outside the Vehicle"
(Section 5.3.2). Switch on the charger and then switch on the DC load.
SECTION 6 | Troubleshooting
6.1 SYMPTOMS: CHARGER POWERED AND CONNECTED TO THE BATTERY
6.1.1 Red LED (2 in Figs 2.1 to 2.3) is OFF
The DC side fuse may have blown due to wrong polarity of battery connection.
Ensure Positive of the battery is connected to the Positive of the charger and the Nega-
tive of the battery is connected to the Negative of the charger. Check the fuses inside
the charger and replace, if blown.
The battery may be shorted. In this condition, the unit is shut down by the short circuit
protection circuit. Remove the battery connection. If the Red LED now comes on, the
battery is shorted. If the Red LED still does not come on, check if there is AC power in
the receptacle. If there is power, check the AC side fuse inside the unit. If the fuse is not
blown, call Technical Support.
6.1.2 Red LED (2 in Figs 2.1 to 2.3) is ON but the Ammeter Shows No Reading
The battery is fully charged. If the battery is not fully charged, the connection to the bat-
tery may be loose or open. Check tightness and continuity of the battery connection.
6.1.3 The Battery Is Getting Over Charged or Boils
The charger is also feeding other DC load(s) in parallel with the battery. The DIP Switch
is not selected for "Battery with Load". Change DIP Switch setting to "Battery with
Load" (see Section 5.2.2 and DIP Switch Settings at Tables 5.1 and 5.2).

SECTION 6 | Troubleshooting
6.2 SYMPTOMS: CHARGER POWERED & DISCONNECTED FROM BATTERY
6.2.1 Red LED (2 in Figs 2.1 to 2.3) is OFF
Check there is AC power in the receptacle. If there is power, check the AC side fuse
inside the unit. If the fuse is not blown, check the DC side fuse. If the DC side fuse is not
blown, the output may be shorted. In this condition, the charger is shut down by the
short circuit protection circuit. Check that the output terminals are not shorted. If the
terminals are not shorted, call Technical Support.
6.2.2 Internal AC Side Fuse Blows as Soon as Power is Turned ON
The AC input is selected for 120 VAC but the unit is plugged into 230 VAC. Always check
that the charger is set for the correct AC mains voltage (Refer to Section 5.2.1). If the AC
input voltage is correct, the charger is defective. Call Technical Support.
6.2.3 DC Side Fuse Blows As Soon As The Battery Is Connected
Wrong polarity of battery connection. Ensure Positive of the battery is connected to the
Positive of the charger and the Negative of the battery is connected to the Negative of
the charger.
6.3 SYMPTOMS WHEN THE CHARGER IS POWERED AND IS BEING USED
AS A DC POWER SUPPLY/UPS
6.3.1 The Voltage Drops When Load is Switched ON
The load is trying to draw current more than the current limit value of the charger
(the current limit value is the maximum specied charging Amps - see Specications
at Section 7). Once the load current reaches the current limit value, the current limit
circuit is activated and the output voltage drops. Some loads like motors, compressors,
incandescent lamps, halogen lamps, heating elements, relays, coils, capacitors etc.
draw very large inrush/starting currents which may reach up to 10 times their normal
operating currents. Ensure that the starting / inrush current or the maximum operating
current of the load is lower than the current limit value of the charger.
i
INFO
Both the AC side and DC sides have fuses that are located inside the charger.
Disconnect the AC power when checking or changing the fuses. Open the
charger as follows:
1. Remove the 4 screws on the ammeter side of the top cover
2. Gently slide the top cover out by about 2 to 3 inches.
(CAUTION! The top cover will be restrained from fully sliding out by the
wires connecting the ammeter , LED and fan)
3. The fuses will now be accessible. See Specications in Section 7 for fuse
ratings.
