2-3. Single UPS Installation
Installation and wiring must be carried out in accordance with the local electric laws and regulations by trained
professionals.
1)
Make sure that the mains wire 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 the wall receptacle as the input power source for the UPS, as its rated current is less than the
UPS’s maximum input current. The receptacle 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 wires based on the following table:

NOTE:
The cable for each Model (i.e. 30K) should be able to withstand given current (i.e. 60A). It is
recommended to use corresponding cable thickness (here, i.e. AWG 8) or thicker wire for Phase and
corresponding (here, i.e. AWG 4) or thicker wire for Neutral for safety and efficiency. The selections for
color of wires should be followed by the local electrical laws and regulations.
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 wire first when making wire connections. Disconnect the earth
wire after you disconnect the power wire.)
