Recommended cross-sectional areas for power cables
For future expansion purpose, it is economical to install power cable according to the full rating capacity initially.
The diameter of cable is shown below (Table 5-2):

Table 5-2 Cross-sectional areas for power cables
•
When selecting, connecting, and routing power cables, follow local safety regulations and rules.
•
If external conditions such as cable layout or ambient temperatures change, perform verification in
accordance with the IEC-60364-5-52 or local regulations.
•
If the rated voltage is 400 V, multiply the currents by 0,95. If the rated voltage is 415 V, multiply the
currents by 0,92.
•
If primary loads are non-linear loads, increase the cross-sectional areas of neutral wires1,5 1,7 times.
•
The nominal battery discharge current refers to the current of forty 12 V batteries at 480V 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.
WARNING
Upon starting, please ensure that you are aware of the location and operation of the external isolators which are
connected to the UPS input/bypass supply of the mains distribution panel. Check to see if these supplies are
electrically isolated. Post necessary warning signs to prevent any inadvertent operation.
