Electrical installation
The interconnection cable connects the indoor and outdoor units. You must first choose the correct ca-
ble size before preparing it for connection.
Then choose the minimum cross-section of the power cable and the interconnecting cable.
The size of the interconnecting cable, power cord, fuse and circuit breaker required 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 select the appropriate cable, fuse or circuit breaker.
Note: The cable core number refers to the detailed wiring diagram attached to the unit you have pur-
chased.
Indoor unit and outdoor unit wiring
1. Some of the indoor and outdoor units have grounding terminals L, which can be powered separately
by the indoor and outdoor units.
2. The schematic diagram in the instruction manual is for information only, it is specific to the units.
