NOTE
When connecting, please make sure to connect input cables and output cables with terminals
firmly. When the input is three-phase, if the UPS is working on Bypass mode, the total current
goes through phase R, so the line widths of phase R must be the same as output. When the input
is single-phase, before doing input connection, users have to use two short wires to connect R&S
and S&T.
3.2 Output Connection
Output connection is configured with terminal blocks. 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, which rated current is less
than the UPS’s maximum input current. Otherwise the receptacle may be burned and destroyed.
