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

2. Remove the electric cover of the outdoor unit.
If there is no cover on the outdoor unit, take
o the bolts from the maintenance board
and remove the protection board.
3. Connect the u-lugs to the terminals
Match the wire colors/labels with the labels
on the terminal block. Firmly screw the u-lug
of each wire to its corresponding terminal.
