3. Installation and Setup
3.5 Single UPS Installation
Installation and wiring must conform with the local electric laws/regulations. The following procedures must be performed by a professional
electrician:
1) Make sure the mains wire and breakers in the building provide adequate power for the rated UPS capacity so as to avoid electrical
shock or fire hazards.
Note: Do not use the wall receptacle as the input power source for the UPS, as its rated current is less than the UPS system's maximum input current.
Otherwise, the receptacle may be shorted and destroyed.
2) Switch off the mains in the building before installation.
3) Turn off all 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.
