breaker is less than 50 kA.
Issue 05 (2019-12-24)
In single mains scenario, the input cable should use the larger specifications between the
mains input and bypass input.
The recommended cables are used only when the following requirements are met:
90° C flexible copper power cable. Multi-core cables are recommended for mains
−
and bypass input and output power cables, and single-core cables are recommended
for battery cables.
− Routing mode: Mains and bypass input and output power cables are routed over a
ladder or bracket (E in IEC60364-5-52), and battery cables are routed over a ladder
or bracket in a single layer (F in IEC60364-5-52).
− The ambient temperature is 30° C.
The AC voltage loss is less than 3%, and the DC voltage loss is less than 1%.
−
Recommended cable lengths: AC power cable ≤ 30 m, DC power cable ≤ 50 m.
