3. Installation and Setup
3.5 Single UPS Installation
Installation and wiring must conform in accordance 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.
