Installation and wiring must be performed by qualified personnel, and in accordance with the local electrical regulations

and codes. Also, you must observe the following instructions:

1) Make sure the mains wire and breakers in the building are enough for the rated capacity of the UPS to avoid the hazards

of electric shock or fire.

Note: Do not use a wall receptacle as the input power source for the UPS, as its rated current is less than the UPS

maximum input current. Failure to do so may result in a broken or burned out receptacle.

2) For safety considerations, turn off the mains switch in the building before installation.

3) Turn off all the devices before connecting them to the UPS.

4) Wiring sizes should be installed in accordance with the following table:
