Stranded Wire
Stranded Wiring Connections
1. Cut the wire end with a wire cutter or wire cutting pliers, then strip the insulation about 3/8"
(10mm).
2. Using a screwdriver, remove the terminal screw(s) on the terminal board.
3. Using crimp or solder connections, securely attach a round terminal to each stripped wire end.
4. Position the round terminal wire, and replace and tighten the terminal screw with a screwdriver.
5. Fix the communication cable and power cable by a cable clamp.
6. After passing the connection cord and power cord through the insulation tube, fasten it with the
cord clamp.
Note:
Match the terminal block numbers and communication wire colors with those of the indoor unit.
WARNING
1. Before starting work, check that power is not being supplied to the indoor unit and outdoor
unit and follow lock-out-tag-out practices.
2. Improperly installed field wiring poses fire and electrocution hazards. Pay special attention to
the wiring of the units.
3. Connect the communication cables firmly to the terminal block. Improper installation may
cause a fire.
4. Always fasten the outside covering of the communication cables with cable clamps. (If the
wire or cable is not clamped, electrical leakage may occur.)
5. Always connect the ground wire.
