● 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
verication 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
conguration.
● The maximum battery discharge current refers to the current when forty 12 V
batteries in standard conguration, 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,
congure input
power cables as mains input power cables. In addition, cables listed in Table
3-2 apply only to the following conditions:
– The cables are installed along the wall or on the
oor (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 Table 3-2 meet the basic
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
exible cables are used.
