1 Electrical wires
2 Insulation
When you connect the electrical wires to a connector on the
electronic board:
∙ Keep a distance of a maximum of 20 mm between
connector and the start of the insulation.
∙ Fix the electrical cables with the clamps installed inside
the heat pump.
4.4.1 Connecting the power input (mains
connection)
The external wiring must be earthed, with correct polarity and
in accordance with current standards.
∙ Always check that the Live and Neutral are connected
correctly.
The cables connecting the switchboard and the heat pump
must be:
- Suitable for a fi xed installation.
- weather resistant.
- equipped with wires adapted to appliance’s power rating.
∙ Connect the heat pump to an electrical panel via an
independent protection system (diff erential breaker with at
least 3 mm between each contact).
Additional protection may be required during installation to
ensure surge category II.
The power supply cut-off devices must allow complete
disconnection of the power under the conditions required for
over-voltage category III.
4.4.1.1 230V heat pump
b Caution!
Risk of damage from too great voltage.
At mains voltages higher than 253 V, electronic
components may be destroyed.
•
Make sure that the rated voltage of the mains
is 230 V.
b Caution!
Risk of malfunction due to the electrical supply.
If the imbalance between the phases of the elec-
trical supply is too large, a malfunction may occur.
•
Install the appliance on a electrical supply with
a maximum imbalance of 2% between phases.
