INSTALLATION INSTRUCTIONS
Step 4: Connect the signal and power cables
The outdoor unit's terminal block is protected by an electrical wiring cover on the side of the unit. A
comprehensive wiring diagram is printed on the inside of the wiring cover.
Cable Types:
• Indoor Power Cable (if applicable): H05V-F or H05V2-F
• Outdoor Power Cable: H07RN-F
• Signal Cable: H07RN-F
All wiring must be performed in accordance with the
wiring diagram located on the inside of the outdoor unit's
wire cover. Do not mix up live and null wires. This is
dangerous and can cause the appliance to malfunction.
1. Prepare the cable for connection:
a. Using wire strippers, strip the rubber jacket from both ends of the signal cable to reveal
about 40 mm (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.
2. Unscrew the electrical wiring cover and remove it.
3. Unscrew the cable clamp below the terminal block and place it to the side.
4. Match the wire colours and labels with the labels on the terminal block and fi 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 around to prevent rain water from
fl owing into the terminal.
6. Using the cable clamp, fasten the cable to the unit. Screw the cable clamp down tightly.
7. Insulate unused wires with PVC electrical tape. Arrange them so that they do not touch any electrical or
metal parts.
8. Replace the wire cover on the side of the unit and screw it into place.
