Before any work inside the device, you must cut the 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 unit to heat up and invalidate the
warranty.
•
Only a qualified and experienced technician is authorised to carry out cabling in the equipment
or to replace the supply cable.
•
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 device is provided for connection to a general power supply with a TT and TN.S neutral regime.
•
Electrical protection: by circuit breaker (D curve) (for calibre, see § “1.2 I Technical specifications”), with a 30 mA
dedicated differential circuit breaker (circuit breaker or switch) at the head of the line.
•
The electricity supply must correspond to the voltage indicated on the device's information plate.

Used the supply cable (RO2V type) adapted for outdoor or buried use (or run the cable into a protection duct).
•
We recommend burying the cable at a depth of 50 cl (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.
Depending on the model, there are 2 ways to connect:
Device not equipped with a cable (Z200 and PI20)
