INFORMATION
In case of preferential kWh rate power supply, connect X11Y to X11YB. The necessity
of separate normal kWh rate power supply to indoor unit (b) X2M/5+6 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.

[9.3] Backup heater
WARNING
The backup heater MUST have a dedicated power supply and MUST be protected by
the safety devices required by the applicable legislation.
CAUTION
To guarantee the unit is completely earthed, always connect the backup heater
power supply and the earth cable.
The backup heater capacity can vary, depending on the indoor unit model. Make
sure that the power supply is in accordance with the backup heater capacity, as
listed in the table below.

at the interface point between the user's
supply and the public system. It is the responsibility of the installer or user of the
equipment to ensure, by consultation with the distribution network operator if necessary,
that the equipment is connected only to a supply with a system impedance Z
sys
less than or
equal to Z
