The battery cable specifications are selected based on 40 batteries by default and
compatible with application scenarios with 30–44 batteries.
When the mains input and bypass input share a power source, configure both types of
input power cables as mains input power cables. The cables listed in
only when the following requirements are met:
−
Routing mode: Routing the cables over the cable ladder or bracket in a single layer
(IEC60364-5-52 middle E). The distances between cables must be greater than
twice the cable diameter.
−
The ambient temperature is 30°C.
−
The AC voltage loss is less than 3%, and the DC voltage loss is less than 1%.
−
90°C copper flexible cable.
−
The length of the AC power cables of a UPS is no longer than 30 m and DC power
cables no longer than 50 m.
When you connect power cables, comply with the tightening torque listed in
ensure secure connections and prevent safety risks.
