3. Installation and Setup
3.4 Single UPS Installation
Installation and wiring must be performed in accordance with local electrical codes/regulations and should only be performed by qualified
personnel.
1) Make sure the mains wire and breakers in the building can sustain the rated capacity of the UPS to avoid electric shock or fire hazard.
Note: Using a wall receptacle as the input power source for the UPS may result in the receptacle burning or being destroyed.
2) Switch off the mains switch in the building prior to installation.
3) Turn off all the connected devices before connecting to the UPS.
4) Prepare the power cables according to Table 3.2. Refer to Table 3.3 for UPS Input Breaker sizes and Table 3.4 for Battery Cabinet
Batteries and Breaker sizes.
WARNING:
• Before connecting any wires, make sure the AC input and battery power are completely shut off.
