1. The nominal DC voltage of external battery pack is 192/240VDC. Each battery pack
consists of 16/ 20 pieces of 12V maintenance free batteries in series. To achieve
longer back time, it is possible to connect multi-battery packs, but the principle of
“same voltage, same type” should be strictly followed.2. The connector of the
external battery cable is used to plug into the external battery socket of the UPS, the
other end of the external battery cable is made of three open wires with ring terminals
to connect with the external battery pack(s). The procedure of installing battery bank
should be complied with strictly. Otherwise you may encounter the hazardous of
electric shock.
1)
A DC breaker must be connected between the battery pack and the UPS. The
capacity of breaker must be not less than the data specified in the general
specification.
2)
Set the battery pack breaker in ”OFF” position and connect the16/20 pieces of
batteries in series.
3)
You must connect the external battery cable to the battery first, if you connect the
cable to the UPS first, you may encounter the hazardous of electric shock.
2. To complete the connection by plugging the connector of the external battery cable
into the external battery socket of the UPS. Do not attempt to connect any loads to
the UPS now. You should connect the input power wire to the right position first. And
then set the breaker of the battery pack in the ON position. After that set the bypass
breaker in the ON position. The UPS begins to charge the battery packs at the time.

1)
After you make sure that the power supply connection is correct, set the bypass
breaker and the input breaker in the “ON/OFF” position first.
At this time the fan
rotates and the UPS supplies power to the load via the bypass. The UPS operates
in Bypass mode.
2)
To power on the UPS by simply pressing the “ON/OFF” button continuously for
more than 1 second.
3)
When being powered on, the UPS will perform self-diagnosis, with the load/battery
level LEDs turned on and then off one after another in ascending order. A few
seconds later, the INV LED is turned on, the UPS is already running in Utility Power
