2-3 Single UPS Installation
Installation and wiring must be performed in accordance with the local electric laws/regulations and the
following instructions should be executed by professional personnel.
1) Make sure the mains wire and breakers in the building are in compliance with the standard of rated capacity
of UPS to avoid hazards of electric shock or fire.
Note: Do not use the wall receptacle as the input power source for the UPS, as its rated current is less than the
UPS maximum input current. This could lead to receptacles being burnt and damaged.
2) Switch off the mains switch in the building before installation.
3) Turn off all the connected devices before connecting to the UPS.
4) Prepare wires based on the following table:

5) Remove the terminal block cover on the rear panel of the UPS. Connect the wires according to the following
terminal block diagrams:
(Connect the earth wire first when making wire connection. Disconnect the earth wire last when making
wire disconnection.)
Terminal block wiring diagram for 6 kVA/10 kVA
Note 1: Make sure that the wires are connected tightly with the terminals.
Note 2: Please install the output breaker between the output terminal, the load and the breaker
should be qualified with leakage current protective function if necessary.
6) Put the terminal block cover back to the rear panel of the UPS.
Warning
Make sure a DC breaker or other protection device between UPS and external battery pack is installed.
If not, please install it carefully. Switch off the battery breaker before installation.
Warning
For standard battery pack, there is one DC breaker to disconnect the battery pack and the UPS. But
for other external battery pack, make sure a DC breaker or other protection device between UPS and
external battery pack is installed. If not, please install it carefully. Switch off the battery breaker before
installation.
Note: Set the battery pack breaker in ‘OFF’ position and then install the battery pack.
