2-5. Single UPS Installation
Installation and wiring must conform in accordance with the local electric laws/regulations and execute the
following instructions by professional personnel.
1)
Make sure the mains wire and breakers in the building provide adequate power for the rated capacity
of UPS to avoid the hazards of electric shock or 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. Otherwise the receptacle may be shorted 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.
