– Routing mode: The cables are routed over a tray or bracket in a single
layer (E in IEC 60364-5-52). The distance between cables should be
greater than twice the cable diameter. Routing mode: The cables are
routed over a tray or bracket in a single layer (E multi-core and G single-
core in IEC 60364-5-52).
– Ambient temperature: 30°C
– The AC voltage loss is less than 3%, and the DC voltage loss is less than
1%.
– Conductor insulation: PVC insulation
– The 90°C flexible cables with copper conductors are used.
– It is recommended that AC power cables be no longer than 30 meters
and DC power cables be no longer than 50 meters.

● The input circuit breakers recommended are for reference only.
● If multiple loads are connected, use recommended specifications for branch circuit
breakers.
● The circuit breaker selection principle is to protect loads and cables, and the cascading
principle is to achieve specific protection.
