2-3. Single UPS Installation
Installation and wiring must be performed in accordance with the local electric laws/regulations and the
following instructions must be executed by professional personnel.
1)
Make sure the mains wire and breakers in the building are enough for the rated capacity of UPS to avoid
the hazards of electric shock or fire.
NOTE:
Do not use the wall receptacle as the input power source for the UPS when its rated current is less
than the UPS’s maximum input current. Otherwise, the receptacle may be burned 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 wires based on the following table:

NOTE 1:
The cable for 30K/30KL should be able to withstand over 63A current. It is recommended to
use AWG 8 or thicker wire for Phase and AWG 4 or thicker wire for Neutral for safety and efficiency.
NOTE 2:
The cable for 40K/40KL should be able to withstand over 80A current. It is recommended to
use AWG 7 or thicker wire for Phase and AWG 4 or thicker wire for Neutral for safety and efficiency.
NOTE 3:
The selections for color of wires should be followed by the local electrical laws and
regulations.
5)
Remove the cover of the terminal block on the rear panel of UPS. Then 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!)
