▪ demand that the equipment only consumes a limited amount of electricity during
certain periods of time.
The indoor unit is designed to receive an input signal by which the unit switches
into forced off mode. At that moment, the unit compressor will not operate.
The wiring to the unit is different depending on whether the power supply is
interrupted or not.
Detail C1: Factory-mounted power supply cable
Wires: 3N+GND, OR 1N+GND
Maximum running current: Refer to name plate on unit.
Connect the factory-mounted power supply cable to a 1N~ or 3N~ power supply.
