When selecting, connecting, and routing power cables, follow local safety regulations
and rules (NFPA 70: National Electrical Code 2017).
If external conditions such as cable layout or ambient temperatures change, perform
verification in accordance with the National Electrical Code (NEC).
The nominal battery discharge current refers to the current of forty 12 V batteries at 480
V in standard configuration.
The maximum battery discharge current refers to the current when forty 12 V batteries in
standard configuration, that is, two hundred and forty 2 V battery cells (1.67 V/cell), stop
discharging.
The battery cable specifications are selected based on 40 batteries by default and
compatible with application scenarios with 30–50 batteries.
When the mains input and bypass input share a power source, configure mains input
power cables as input power cables. In addition, cables listed in
apply only to the following conditions:
− There are not more than three current-carrying conductors in each cable trough or
pipe.
− The ambient temperature is 30° C.
− The AC voltage loss is less than 3%, and the DC voltage loss is less than 1%.
− The cable is of the 90° C copper conductor type in the NEC (2017) Table 310.15 (B)
(16).
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.
