If external conditions such as cable layout or ambient temperatures change, perform verification in
accordance with the IEC-60364-5-52 or local regulations.
You must abide by the local rules and regulations when bridging and wiring AC cables.
The currents listed in
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 wires 1.5–1.7 times.
When you connect power cables, comply with the tightening torque listed in
ensure secure connections and prevent safety risks.

Routing mode: Routing the cables over the cable ladder or bracket in a single layer (the routing
mode for DC cables is F in IEC60364-5-52 and the routing mode for AC cables is E in IEC60364-5-
52).
Ambient temperature: 30° C
The drop amplitude of AC voltage is less than 3% and DC voltage less than 1%. The length of the
AC power cables of a 400 kVA or 500 kVA UPS is no longer than 30 m and DC power cables no
longer than 50 m.
