1.4 I  Power supply connections

•  Before any work inside the appliance, you must cut the appliance’s electricity supply as there 

is a risk of electric shock which may cause material damage, serious injury or even death. 

•   Incorrectly tightened terminals may cause the terminal box to heat up, which can invalidate 

the warranty.

•  Only a qualified and experienced technician is authorised to carry out cabling work within the 

appliance or to replace the power cord.

•  The installer must consult the electricity provider if necessary and ensure that the equipment 

is connected correctly to an electricity network with impedance under 0.095 ohm.

• 

The heat pump's electrical supply must be provided through a protection and circuit breaking device (not supplied) 

complying with the standards and regulations in force in the country where it is installed.

• 

The appliance is provided for connection to a general power supply with a TT or TN-S neutral regime.

• 

Electrical protection: by circuit breaker (D curve, rating to be defined according to the table in § “5.2 I  Technical 

specifications”), with a suitable dedicated residual-current device (circuit breaker or switch).

• 

Additional protection may be required during installation to guarantee the overvoltage category II.

• 

The power supply must correspond to the voltage indicated on the appliance's information plate.

• 

The power cord must be insulated against any cutting or hot elements that may damage or crush it.

•  The appliance must be connected to an earth socket.

• 

The electrical connection lines must be fixed.

•  Use the gland to pass the power cord into the appliance.

• 

Use the power cord (RO2V type) adapted for outdoor or buried use (or run the cable into a protection duct) with an 

external diameter of between 9 and 18 mm. 

• 

We recommend burying the cable at a depth of 50 cm (85 cm under a road or path) in an electrical duct (red ribbed). 

• 

If this buried cable meets another cable or pipe (gas, water, etc.), there must be more than 20 cm between them.

•  Connect the power cord to the terminal block inside the appliance.
