Step 6: Connect signal and power cables

The signal cable enables communication
between the indoor and outdoor units. You must
first choose the right cable size before preparing
it for connection.
Cable Types
• Indoor Power Cable (if applicable):
H05VV-F or H05V2V2-F
• Outdoor Power Cable: H07RN-F
• Signal Cable: H07RN-F
Minimum Cross-Sectional Area of Power and
Signal Cables
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 cur-
rent 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.
TAKE NOTE OF FUSE SPECIFICATIONS
The air conditioner's circuit board (PCB) is
designed with a fuse to provide overcurrent
protection. The specifications of the fuse are
printed on the circuit board, such as:
T3.15A/250VAC, T5A/250VAC, etc.
1. Prepare the cable for connection:
a. Using wire strippers, strip the rubber
jacket from both ends of signal cable to
reveal about 1.57 in of the wires inside.
b. Strip the insulation from the ends of the
wires.
c. Using wire crimper, crimp u-type lugs on
the ends of the wires.
PAY ATTENTION TO LIVE WIRE
While crimping wires, make sure you clearly dis-
tinguish the Live ("L") Wire from other wires.
2. Open front panel of the indoor unit.
3. Using a screwdriver, open the wire box cover
on the right side of the unit. This will reveal the
terminal block.
WARNING
ALL WIRING MUST PERFORMED STRICTLY IN
ACCORDANCE WITH THE WIRING DIAGRAM
LOCATED ON THE INSIDE OF THE INDOOR
UNIT'S WIRE COVER.
4. Unscrew the cable clamp below the terminal
block and place it to the side.
5. Facing the back of the unit, remove the plastic
panel on the bottom left-hand side.
