Connect signal and power cables
Before performing any electrical or wiring work, turn off the mains power to the system.
All wiring must be performed in accordance with the wiring diagram located on the
inside of the wiring cover.
The signal cable enables communication between the indoor and outdoor units. You must
choose the right cable size before preparing it for connection. The size of the power supply
cable, signal cable, fuse, and switch is determined by the maximum current of the unit. The
maximum current is indicated on the data plate located on the side panel of the unit.
The outside unit’s terminal block is protected by an electrical wiring cover on the side of the
unit.
1. Prepare the cable for connection. Using wire strippers, strip the rubber jacket from both
ends of the cable to reveal approximately 40 mm of the wires inside. Strip the insulation
from the ends of the wires. Using a crimper, crimp u-lugs on the ends of the wires. While
crimping make sure to clearly distinguish the live wire from the other wires.
2. Unscrew the electrical wiring cover and remove it.
3. Unscrew the cable clamp below the terminal block and
place it to one side.
4. Connect the wires according to the wiring diagram, and
firmly screw the u-lug of each wire to it’s corresponding
terminal.
5. After checking to make sure every connection is secure, loop the wires around to prevent
rain water from entering 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 in place.
