Fix the cable with cable ties to the cable tie mountings to ensure
strain relief and to make sure that it does NOT come in contact
with the piping and sharp edges.
3.5.3 To connect the main power supply
1
Connect the main power supply.
In case of normal kWh rate power supply
Legend: see illustration below.
In case of preferential kWh rate power supply
2
Fix the cable with cable ties to the cable tie mountings.
3.5.4 To connect the backup heater power supply
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.
1
Connect the backup heater power supply.
For *3V models, use a single pole fuse for F1B. For *9W models,
use a double pole fuse for F1B.
CAUTION
Do NOT push or place redundant cable length in the unit.
a
Interconnection cable (=main power supply)
b
Normal kWh rate power supply
c
Preferential power supply contact
INFORMATION
In case of preferential kWh rate power supply, 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.

CAUTION
If the indoor unit has a tank with a built-in electrical booster
heater, use a dedicated power circuit for the backup heater
and booster heater. NEVER use a power circuit shared by
another appliance. This power circuit must be protected with
the required safety devices according to the applicable
legislation.

(a)
Equipment complying with EN/IEC 61000-3-12
(European/International Technical Standard setting the limits for
harmonic currents produced by equipment connected to public low-
voltage systems with input current >16 A and
≤
75 A per phase.).
(b)
This equipment complies with EN/IEC 61000-3-11
(European/International Technical Standard setting the limits for
voltage changes, voltage fluctuations and flicker in public low-voltage
supply systems for equipment with rated current
≤
75 A) provided
that the system impedance Z
sys
is less than or equal to Z
max
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
max
.
