1) Make sure the mains wire and breakers in the building are enough 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
