Electrical connections
• Always check that the electric power supply is
switched off before works.
• Characteristics of the electrical power supply
The electrical installation must be conducted in
accordance with the regulations in effect:
For installations with no neutral, a galvanic insulation
transformer earthed to the secondary must be used.
The electrical connections will only be made when
all of the other assembly operations (attachment,
assembly, etc.) have been carried out.
Warning!
The contract taken out with the energy supplier
must be sufficient to cover the power of the heat
pump as well as the sum of the power requirements
of all of the appliances likely to be operated at the
same time. If the power supply is insufficient, check
with your energy supplier the value of the power
supply defined in your contract.
Never use a socket for the power supply.
The heat pump must be directly powered (without
external switch) by dedicated lines that are protected
from the electrical housing by bipolar circuit breakers
dedicated to the heat pump, curve D for the outdoor
unit, curve C for the electrical DHW back-ups
(see
“Specifications”, page 7
).
The electrical installation must be equipped with a
differential protection of 30 mA.
This appliance is designed to operate under a
nominal voltage of 230 V +/- 10%, 50 Hz.
• General remarks on electrical connections
It is essential to maintain the phase-neutral polarity
when making the electrical connections.
Rigid wire is always preferable for fixed installations,
especially in buildings.
Clamp the cables with stuffing glands to avoid any
accidental disconnection of the conductive wires.
Connection to earth and earth bonding continuity
are essential.
• Connecting to screw terminals
Use of ring terminals or tips is prohibited.
-
Always choose a wire that complies with current
standards.
-Strip the end of the wire over a length of around
25 mm.
-With round nosed pliers, make a loop with a
diameter that corresponds to the terminal's
tightening screws.
-
Tighten the terminal screw on the loop very firmly.
Insufficient tightening can cause overheating,
leading to breakdown or even a fire.

• Connecting to regulation boards
-Remove the corresponding connector and make
the connection.
Precabled wiring connector and/or screw connector
• Connecting to spring terminals
-Strip the end of the wire over a length of around
10 mm.
-Push the spring with a screwdriver so that the wire
enters the cage.
-Slide the wire into the opening provided for this
purpose.
-Remove the screwdriver and then check that the
wire is jammed in the cage by pulling on it.
