Connection requirements
1. The AC in cables are wired from the distribution switch, and connected to the output terminal when the power is to
be switched on. The AC input is fitted with overcurrent, short circuit and lightning protection devices. The capacity of
the distribution switch should be no less than 1.5 ~ 2 times of the load capacity.
2. The yellow, green, red, and light blue AC cables correspond respectively to the AC phase A, B, C and neutral lines.
If the cables are the same color, they should be numbered or identified with insulating tape of different colors at both
cable ends.
3. The AC cables should be run separate from the DC cables, with separation exceeding 150mm.
4. No splice, damage, or scratch on the cables is permitted.
