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.
• 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.
• Means for disconnecting from the mains supply for all poles guaranteeing full disconnection
in the over-voltage category III must be compliant and incorporated into the wiring.
• To access the electrical connection terminal boards:
x2 screws
Unscrew the 2 screws
• 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 (C or D curve) (for rating, see § "5.2 I Technical data"), with a 30 mA dedicated
residual-current protection system (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 correctly connected to a suitable earth/ground circuit.
• The electrical connection lines must be fixed.
• Use the gland to pass the power cord into the appliance.
• Use the power cord (H07RN-F type) adapted for outdoor or buried use (or run the cable into a protection duct) with
an external diameter of between 13 and 18mm.
• 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 supply cord to the spring-cage terminal block inside the appliance (see § "1.3.1 I Wiring on a
spring-cage terminal block").
Information: three-phase model terminal boards
• On three phase models, there is no live order to be respected.
