1. Safety Instructions

1-1. Warnings and symbols

Safety instructions and warnings are marked in this manual by the following pictograms：

Supplementary information on operating the device.

CAUTION

Safety instruction: Failure to observe this instruction can cause material damage and

impair the function of the device.

CAUTION

Safety instruction relating to a danger from an electrical current or voltage. Failure to

observe this instruction can cause material damage and personal injury and impair the

function of the device.

WARNING!

SAVE THESE INSTRUCTIONS – This manual contains important instructions that should

be followed during installation and maintenance of the unit.

1-2. Use for intended purpose general safety precautions

The unit is constructed as per the applicable safety-technical guidelines.

 For the charging of lead acid batteries and the supply of user attached to these batteries, in

permanent systems.

 For the conversion of a DC voltage from a battery to and AC voltage.

 Do not expose the unit to rain, snow, spray or dust. To reduce the risk of fire hazard, do not cover or

obstruct the ventilation openings and. do not install the unit in a zero-clearance compartment.

 To avoid the risk of fire and electric shock, make sure that the existing wiring is in good electrical

condition; and that the wire size is not undersized.

Do not operate the unit with damaged or substandard wiring.

 Depending on the use, the AC output of the unit may require user installed breaker or fusing. The

unit incorporates standard AC short circuit protection.

 The following precautions should be taken when working on the Inverter Charger：

 Remove watches, rings, or other metal objects.

 Use tools with insulated handles.

 Wear rubber gloves and boots.

1-3. Other safety notes and installation precautions

 Upon receipt, examine the shipment box for damage. Notify the carrier immediately, before opening,

if damage is evident.

 Do not operate near water or in excessive humidity.

 Do not open or disassemble the unit, warranty may be voided.

2

EN

 The DC and AC side connections should be firm and tight.

 Grounding：Reliable grounding of rack-mounted equipment should be maintained.

 Do not drop a metal tool on the battery. The resulting sparks or short-circuit on the battery or on the

other electrical part may cause an explosion.

 Wiring：Adequate input power must be supplied to the unit for proper use; correct wiring sizes must

be ensured.

 Do not operate the unit close to combustible gas or open fire.

 Temperature：The unit should be operated in an ambient temperature range of -20 to 40°C or else

the output efficiency may be affected. Air flow to the unit must not be restricted.

 In case of fire, you must use the fire extinguisher which is appropriate for electrical equipment.

 Short circuiting or reversing polarity will lead to serious damage to batteries, unit and the wiring.

Fuses between the batteries and the unit cannot prevent damage caused by reversed polarity and

the warranty will be void.

 Do not work on unit or system if it is still connected to a power source. Only allow changes in your

electrical system to be carried out by qualified electricians.

 Check the wiring and connections at least once a year. Defects such as loose connections, burned

cables etc. must be corrected immediately.

 Do not touch the equipment when wet or if your hands are clammy.

CAUTION

The cabinet of the unit must not be opened. There are no serviceable parts inside the

cabinet. Only qualified, authorized and trained electrician installers are authorized to open

the connection compartment.

1-4. Warning regarding the use of batteries

Excessive battery discharge and / or high charging voltage can cause serious damage to batteries. Do

not exceed the recommended limits of discharge level of your batteries. Avoid short circuiting batteries,

as this may result in explosion and fire hazard. Installation of the batteries and adjustments of the unit

should only be undertaken by authorized personnel!

This connection is used to tie the exposed chassis of the inverter to the DC grounding

system. This terminal accepts CU/AL conductors from #14 to #2 AWG (2.1 to 33.6 mm2).

WARNING!

The ground wire offers protection only if the cabinet of the unit is

connected to the safety ground. Connect the chassis ground.

Terminal to the hull or the chassis.

Refer to local regulations on these issues!

For safety purposes the neutral conductor (N) of the AC output must be connected to the

earth (PE / GND) when the unit is in inverter operation. When utility power is available on

the AC input, and the unit is in charger mode, this connection must be disabled again.

In some applications automatic connection between the neutral conductor (N) and earth

(PE / GND) is not required or acceptable. Therefore the automatic connection between the

neutral conductor (N) and earth (PE / GND) is enabled by default.

connector

Follow the instructions to connect the battery cables to the DC input terminals of the unit.

The cables should be as short as possible (less than 6 feet / 1.8 meters ideally) so that they

can handle the required current in accordance with the Electrical Codes and Regulations.

The size of the cable should be thick enough to limit the voltage drop to less than 2% when

carrying the maximum input current to prevent frequent low-input voltage warnings, and

shutdown. UVP (Under Voltage Protection) warning may result if there is excessive voltage

drop across the DC cables between the batteries and the unit. Increasing your DC cable size

will help improve the situation.

Batteries are capable of providing very large currents in case of short circuit. In case there is

a short circuit in the cable run between the batteries and the input terminals of the unit, it will

result in overheating / melting of the cables and consequent risk of fire and injury, to prevent

possibility of this hazard, use Very Fast Acting DC Fuse in line with the positive cable. The

fuse should be as close to the positive battery terminal as possible.

The following sizes of cables and fuses are recommended for up to 6 ft. distance between

the batteries and the unit.
