1. Important Safety Information

WARNING!

Before using the inverter, read and save the safety instructions.

1-1. General Safety Precautions

1-1-1. Do not expose the Inverter to rain, snow, spray, bilge or dust.

To reduce risk of hazard, do not cover or obstruct the ventilation openings. Do

not install the inverter in a zero-clearance compartment. Overheating may

take place.

1-1-2. To avoid a risk of fire and electric shock, please make sure that existing wiring

is in good electrical condition; and that wire size is not undersized. Do not

operate the Inverter with damaged or substandard wiring.

1-1-3. This equipment contains components which can produce arcs or sparks.

To prevent fire or explosion do not install in compartments containing batteries

or flammable materials or in locations which require ignition protected

equipment. This includes any space containing gasoline-powered machinery,

fuel tanks, joints, fittings, or other connection between components of the fuel

system.

1-1-4. An over current protection at the time of installation shall be provided by

others for the AC output circuit.

1-1-5. Additional breakers suitable for 20 A branch circuit protection shall be

provided for the GFCI receptacles.

1-2. Precautions When Working with Batteries

1-2-1. If battery acid contacts skin or clothing, wash immediately with soap and water.

If acid enters eye, immediately wash eyes with running cold water for at least

20 minutes and get medical attention immediately.

1-2-2. Never smoke or allow a spark or flame in vicinity of battery or engine.

1-2-3. Do not drop a metal tool on the battery. The resulting spark or short-circuit on

the battery or other electrical part may cause an explosion.

1-2-4. Remove personal metal items such as rings, bracelets, necklaces, and

watches when working with a lead-acid battery.

A lead-acid battery produces a short-circuit current high enough to weld a ring

or similar item to metal causing a severe burn.

EN

1-3. Installation

The power inverter should be installed in a location that meets the following

requirements：

Dry – Do not allow water to drip or splash on the inverter.

Cool – Ambient air temperature should be between -20℃ and 50℃, but he cooler

the better.

Safety – Do not install batteries in the compartment or other areas here flammable

fumes existence such as fuel storage areas or engine compartments.

Ventilated – Allow at least one feet of clearance around the Inverter for air flow.

Ensure the ventilation shafts on the rear and bottom of the unit are not

obstructed.

Dust-free – Do not install the Inverter in dusty environments here dust, wood

particles or other filings/shavings are present. The dust can be pulled

into the unit when the cooling fan is in operation.

Close to batteries – Avoid excessive cable lengths but do not install the inverter in

the same compartment as batteries.

Use the recommended wire lengths and sizes (refer to section 4.DC wiring

connections).

Do not mount the inverter where it is exposed to the gases produced by the battery.

These gases are very corrosive and prolonged exposure will damage the inverter.

WARNING!

Shock Hazard. Before proceeding further, carefully check that the inverter is

NOT connected to any batteries, and that all wiring is disconnected from any

electrical sources . Do not connect the output terminals of the inverter to an

incoming AC source.

 User-friendly remote control

 Automatic master mechanism to eliminate single point failure and optimize

reliability

 Built-in ATS and AC circuit breaker

 Optional STS module, transfer time is less than 4ms.

 RS-232 communication

 Input & output fully isolation

 Output voltage / power saving mode is selectable by DIP switch and remote

control (CR-10)

 Input Protection：Reverse Polarity (Fuse) / Under Voltage / Over Voltage

Protection

 Output Protection：Short Circuit / Overload / Over Temperature / Over Voltage

Protection

To get the most out of the power inverter, it must be installed and used properly.

Please read the instructions in this manual before installation and operation of this

model.

3-1. Power ON / OFF / REMOTE (Main) switch

A. Before installing the inverter, please ensure the main switch is in the OFF position.

B. Before using the remote unit, please ensure the main switch is in the REMOTE

position.

C. Main switch ON / OFF will not control AC Grid input, therefore for any

maintenances please remove the AC Grid connection to prevent damage of SD

series, then turn off the Main switch to OFF position for maintenance service.

3-3-2. Power Saving Mode

Power Saving Mode is adjustable and set by the Dip Switches,S4, S5 and S6 on the

front panel. Example SD2500：Saving set 2%, the load is below 50W 10 sec. will into

saving mode, more than 150W or more leave saving mode.

A. Power device enter the saving mode

The rate power x setting % = the threshold enter the power saving model

In case the load less than threshold value 10 seconds, the power device will enter

the saving mode.

1=ON/0=OFF

15

B. Power device leaving saving mode(re-start)

Restart threshold = rate power x setting % x 2~3

In case the power over the restart threshold, the power device will re-start and

provide the AC power.

WARNING!

Operating the inverter without a proper ground connection may cause electrical

safety hazard.

3-8. By-pass AC input (please refer to hard wiring installation on P.22)

3-9. AC input circuit breaker

The AC input circuit breaker protects the model from overload. When an overload

condition exists, the circuit breaker stops supplying output AC grid power. To reset it,

push the circuit breaker switch then the model will be back in normal operation. The

source fault should be corrected before you reset it.

Figure 9. CAN1 and CAN2 port

1. Before using parallel mode, you need to ensure the green terminal’s parallel jump

status is set to ON.

2. Use the RJ-45 line (RJ-45 network cable：parallel connection) to link one of the

SD Series CAN1 (CAN2) port to the other CAN1 (CAN2) port.
