When selecting, connecting, and routing power cables, follow local safety
regulations and rules.
When the external conditions change, for example, the cable layout or
ambient temperatures, perform verification in accordance with the
IEC-60364-5-52 or the 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.
When the primary loads are non-linear loads, increase the cross-sectional
areas of the neutral wires 1.5–1.7 times.
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.
When the mains input and bypass input share a power source, configure input
power cables as mains input power cables. In addition, cables listed in
3-2
apply only to the following conditions:
–
The cables are installed along the wall or on the floor (IEC-60364-5-52 C
standards).
–
The ambient temperature is 30°C.
–
The AC voltage loss is less than 3%, and the DC voltage loss is less than
1%. The recommended cable diameters in
through-current requirements. Users should evaluate the line voltage loss
based on the actual cable length. If the voltage loss exceeds the
requirements, increase the cable diameter properly.
–
Single- or multi-core 90°C-resistant copper flexible cables are used.
