CHOOSE THE RIGHT CABLE SIZE
The size of the power supply cable, signal cable,
fuse, and switch needed is determined by the
maximum current of the unit. The maximum
current is indicated on the nameplate located on
the side panel of the unit. Refer to this nameplate
to choose the right cable, fuse, or switch.
NOTE: In North America, please choose the
right cable size according to the Minimum Circuit
Ampacity indicated on the nameplate of the unit.
b. Using wire strippers, strip the rubber
jacketfrom both ends of the signal cable to
reveal approximately 15cm (5.9") of wire.
c. Strip the insulation from the ends.
d. Using a wire crimper, crimp u-lugs on the
ends.
NOTE: When connecting the wires, strictly follow
the wiring diagram found inside the electrical box
