1.3 I Electricity supply connections
• Before any work inside the appliance, you must cut the electricity supply as there is a risk of
electric shock which may cause material damage, serious injury or even death.
• Poorly tightened cabling terminals can cause the cables to overheat at the terminals and create
a fire risk. Make sure that the terminal screws are fully tightened. Incorrectly tightened terminal
screws will cancel the warranty.
• Only a qualified and experienced technician is authorised to carry out cabling work within the
appliance or to replace the power cord.
• Do not disconnect the electricity supply when the appliance is running. If the electric power
supply is interrupted, wait a minute before restoring the power.
• 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 and TN.S neutral regime.
• Electrical protection: by circuit breaker (D curve, rating to be defined according to the table, see § "5.2 I Technical
data"), with a 30 mA dedicated residual-current protection system (circuit breaker or switch).
• An electrical switch for disconection OVC III category must be installed in the fixing wiring, in accordance with
applicable national laws.
• 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 correctly connected to a suitable earth/ground circuit.
• The electrical connection lines must be fixed.
• Use the cable gland and cable clamp 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), see
§"1.3.1 Cable cross section" for more details.
• 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.
