Installation standards in force
Important
The installation must be fitted with a main switch.
Caution
Power the appliance via circuits that include omni-polar switches
with contact opening distance of 3 mm or more.
Single phase models: 230 V (+6%/-10%) 50 Hz
The installer must provide the power supply cables and connect them.
Caution
Secure the cables with the cable ties supplied. Be careful that you
do not invert any of the wires.
5.11.2 Recommended cable cross section
The electrical characteristics of the mains power supply available must
correspond to the values given on the data plate.
The cable will be carefully chosen according to the following information :
Maximum intensity of the outdoor unit. See table below.
Distance of the appliance from the original power supply
Upstream protection.
Neutral operating conditions.
Important
The maximum permissible current on the power supply cable of
the indoor unit must not exceed 6 A.

Important
For the "inverter" outdoor unit power supply, use a residual-
current device (RCD) compatible with high harmonics:
a type A residual-current device may be sufficient for single-
phase applications,
if not, a type B or equivalent residual-current device may be
sufficient for three-phase and single-phase applications.
