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.
Cable Types
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

NOTE: The fuse is made of ceramic.
Prepare the cable for connection:
1.
Using wire strippers, strip the rubber jacket

from both ends of signal cable to reveal
about 40mm (1.57in) of the wires inside.
Strip the insulation from the ends of the
b.
wires.
Using wire crimper, crimp u-type lugs on
c.
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.
