3.3 Making the electrical
connections
B For BUS connection use AWG 18 (0.75 mm
cable and do not exceed 492 ft. (150 m) total
length.
B Route all low-voltage cables separately from
cables carrying line voltage to avoid inductive
interference (minimum separation 4"
(100 mm)).
B In case of inductive external influences, use
shielded cables.
This way, the cables are shielded against
external influences (e.g. high-voltage cables,
contact wires, transformer stations, radio and
TV devices, amateur radio stations, microwave
devices, etc.).
