Step 6: Connect signal cable

The signal cable enables communication between 
the indoor and outdoor units. You must first 
choose the right cable size before preparing it for 
connection.

Indoor Power Cable

 (if applicable): 

H05VV-F or H05V2V2-F

• 

Outdoor Power Cable:

 H07RN-F

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.

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 15cm (6in) 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 
distinguish 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.

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.
