4.1 Connecting external battery

1. 

It is recommended to install a DC Breaker in a positive battery line. 

The rating of the DC Breaker must be at least 75Ah to guarantee safe 

operation without interruption. Keep the DC Breaker off.

NOTE!

For the user operation safety we strongly recommend that you should use 

tapes to isolate the battery terminals before you start to operate the UPS.

A. Single battery connection

When using a single battery its voltage must be equal to the Nominal DC 

Voltage of the unit.

B. Multiple batteries in series connection

All batteries must be equal in voltage and amp hour capacity. The sum of 

their voltages must be equal to the nominal DC Voltage of the unit.

C. Multiple batteries in parallel connection

Each battery’s voltage must be equal to the Nominal DC Voltage of the unit.

It’s very important for system safety and efficient operation to use 

appropriate external battery cable. To reduce risk of injury, external 

battery cables should be rated for 75° C or higher. Do 

NOT

 use 

copper cables with less than 10mm in cross sectional area!

CAUTION

2. 

Make sure to connect the polarity of battery side and the unit correctly. 

Positive pole (Red) of battery to the positive terminal (+) of the unit. 

Negative pole (Black) of battery to the negative terminal (-) of the unit.

3. 

After connecting the battery to the UPS use tape to isolate the external 

battery terminals.

4.2 Connecting to utility and charge

Plug in the AC input cord to the wall outlet. The unit will automatically 

charge the connected external battery even though the unit is off.

The unit may have output power when is connected to the utility, 

even though it is powered off. To completely cut off the output 

power, please switch off the unit and disconnect.

CAUTION

4.3 Starting the UPS

Please make sure that the battery is connected before you turn ON the 

UPS. If your battery is connected you can turn ON the ON/OFF switch 

and charge the battery or batteries at least 8 hours for a full load.

NOTE!

The battery or batteries connected to the UPS must be at least 38Ah each to 

guarantee safe operation without interruption.
