1. Prepare the cable for connection:
USE THE RIGHT CABLE
● Indoor Power Cable (if applicable):
H05VV-F or H05V2V2-F
● Outdoor Power Cable: H07RN-F
● Signal 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.
a. Using wire strippers, strip the rubber
jacket from both ends of cable to reveal
about 40mm (1.57in) of the wires inside.
b. Strip the insulation from the ends of the
wires.
c. Using a wire crimper, crimp u-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.

3. Unscrew the cable clamp below the
terminal block and place it to the side.
4. Connect the wire according to the wiring
diagram, and rmly screw the u-lug of
each wire to its corresponding terminal.
5. After checking to make sure every
connection is secure, loop the wires
