2-3. Single UPS Installation
Installation and wiring must be carried out in accordance with the local installation regulations by trained
professionals.
1) Make sure that the mains cable and breakers of the building are rated for the capacity of the UPS to
prevent electric shock or risk of fire.
NOTE: Do not use a standard wall mains socket as the input power source for the UPS, as its rated current
is less than the UPS’s maximum input current. The socket may be damaged and destroyed.
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 cables based on the following table:
Wiring spec (mm² & Max A Per Phase)
NOTE 1: The selection for cable sizing should be based on the cable specification used and the type
of cable installation. Local electrical laws and regulations should be followed.
NOTE 2: The selections for color of cables should be followed by the local electrical laws and
regulations.
NOTE 3: Maximum current is based on Input Voltage of 209V, 130% load with 12A Charger fully
operating.
5) Remove the terminal block cover at the rear panel of UPS. Then connect the wires according to the
following terminal block diagrams: (Connect the grounding/earthing wire first when making wire
connections. Disconnect the earth wire after you disconnect the power wire.)
