Remark:
when the main load is a kind of linear load, the N line cable can be selected the same cross
sectional area as the mains live line cable; when the main load is a kind of non-linear load, the Null current is 1.5-
1.7 times as big as the Live current, and it needs to be selected according to the recommended N line cable current
in the above table. If it is multiconductor cable, it should be selected according to the cross sectional area of the N
line cable.
Terminal block
Note
：
Ensure that the input / output cables must be connected firmly to the input / output terminals, bad contacts
are not allowable. It is suggested that the earth wire is close to the input / output wire size.
3.2.3 Connect external battery (Long time model UPS)
The default configuration of Long time model UPS use 16pcs batteries, standard model UPS use 20pcs as default. If it was
customized to be 14/16/18/20pcs before factory delivery, connect proper batteries according to the customized battery
quantity. If need to change battery configuration, contact your local dealer for modification.
Strictly follow these steps:
Battery switch is OFF, connect batteries in series and ensure proper battery voltage.
Battery cables must be connected to the battery terminal first (Connecting to the UPS terminal first has hazard of
electric shock), red wire is connected to BAT+, black wire to BAT-.
Use proper battery cables to connect the UPS and batteries. The DC breaker between UPS and batteries is required.
Not to connect UPS to any loads first, close the battery breaker and provide mains power to the UPS (close the UPS input
breaker), UPS will charge the battery group.
