NOTICE
To guarantee electromagnetic compatibility:
▪ Make sure both power supply and communication
cables run parallel to one another. Use tie straps to
hold the cables together.
▪ Make sure the cables are located as far away from the
compressor as possible.
▪ The communication cable MUST pass through the
ferrite core.
5 Make sure that the cable does NOT come in contact with sharp
edges or hot gas piping.
6 Install the switch box cover.
INFORMATION
When installing field supply or option cables, foresee
sufficient cable length. This will make it possible to remove/
reposition the switch box and gain access to other
components during service.
