INFORMATION
Some types of preferential kWh rate power supply require
a separate normal kWh rate power supply to the indoor
unit. This is required in the following cases:
▪ if the preferential kWh rate power supply is interrupted
when active, OR
▪ if no power consumption of the indoor unit is allowed at
the preferential kWh rate power supply when active.
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.

Maximum length: 50 m.
Preferential kWh rate power supply contact: 16 V DC
detection (voltage supplied by PCB). The voltage-free contact
shall ensure the minimum applicable load of 15 V DC, 10 mA.
Connect the preferential kWh rate power supply contact (S1S) as
follows.
