Fix the cable with cable ties to the cable tie mountings.

INFORMATION

In case of preferential kWh rate power supply, connect
X6Y to X6YB. The necessity of separate normal kWh rate
power supply to indoor unit (b) X2M30/31 depends on the
type of preferential kWh rate power supply.

Separate connection to the indoor unit is required:

▪ if 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.
