Outdoor Unit Wiring
WARNING
Before performing any electrical or
wiring work, turn off the main
power to the system.
1. Prepare the cable for connection
a. You must first choose the right
cable size. Be sure to use H07RN-
F cables.
NOTE: In North America, choose the
cable type according to the local
electrical codes and regulations.
Minimum Cross-Sectional Area of Power
and Signal Cables (For reference)
Rated Current of
Appliance (A)
> 3 and ≤ 6
> 6 and ≤ 10
> 10 and ≤ 16
> 16 and ≤ 25
> 25 and ≤ 32
> 32 and ≤ 40
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 jacket from both ends of the
signal cable to reveal approxima-
tely 15cm (5.9") of wire.
c.
Strip the insulation from the ends.
d.
Using a wire crimper, crimp u-
lugs on the ends.

Indoor Unit Wiring
1. Prepare the cable for connection.
a.
Using wire strippers, strip the rubber ja-
cket from both ends of the signal cable
to reveal about 15cm (5.9") of the wire.
Strip the insulation from the ends of the
b.
wires.
c. Using a wire crimper, crimp the u-lugs
to the ends of the wires.
2. Remove the cover of the electric
control box on your indoor unit.
3. Connect the u-lugs to the terminals.
Match the wire colors/labels with the
labels on the terminal block. Firmly
screw the lug of each wire to its
corresponding terminal. Refer to the
Serial Number and Wiring Diagram
located on the cover of the electric
control box.
