5. Ensure the capacity of mains power supply. Do not use the wall receptacle as the input power source for
the UPS, as its rated current is less than the UPS's maximum input current. Otherwise the receptacle may be
burned and destroyed.
6. The protective earth ground wire should be installed first according to the following diagram. It is better to
use green wire or green wire with yellow ribbon wire.
7. Connect other input and output wires to the corresponding input and output terminals according to the
following diagram.
Note: Make sure that the input and output wires and the input and output terminals are connected tightly.

8. It is requested to use the accessorial terminal splices which can be compacted on the wires tightly, to
ensure the connection between the wires and the terminal block is reliable.
9. Install an output breaker between the output terminal of UPS and the load, and the breaker should be with
leakage current protective function if necessary.
10. Turn off all the loads first before connecting the load with the UPS, then perform the connection and
finally turn on the loads one by one.
11. After completing the installation, please check the wires to make sure all were connected correctly and
tightly.
12. Suggest charging the batteries for 8 hours before use. After Installation, turn on the mains power switch
and turn the input breaker in the "ON" position, the UPS will charge the batteries automatically. It can also
use the UPS immediately without charging the batteries, but the backup time may be less than the standard
value.
13. If it is necessary to connect the inductance load such as a monitor or a laser printer to the UPS, the start-
up power should be used for calculating the capacity of the UPS, as its start-up power consumption is too big
to make the UPS which capacity is small fail easily.
External Battery Pack Connecting Procedure:
The nominal DC voltage of external battery pack is 192Vdc. To achieve longer backup time, it is possible to
connect multi-battery packs, but the principle of "same voltage, same type" should be strictly followed.
1. Loosen the screws to remove the Battery Input Connector Cover of Power Module.
