I Electricity Supply Connections - Zodiac Heat Select ZS500 Series Instructions For Installation And Use Manual

1.3 I Electricity supply connections

• Before performing any work inside the device, you must disconnect the electrical power
supply to the appliance 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 in the equipment
or to replace the supply cable.
• Improperly tightened wiring terminals can cause overheating of wiring at the terminals, which
can lead to a fire hazard. Be sure to ensure that terminal screws are properly tightened.
Improperly tightened terminal screws will invalidate the warranty.
• Do not disconnect the electricity supply when the device is running. If the electric power
supply is interrupted, wait a minute before restoring the power.
• Means for disconnection from the supply mains having a contact separation in all poles that
provide full disconnection under overvoltage category III, must be incorporated in the fixed
wiring in accordance with the wiring rules.

Access to the technical compartment
• 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 § "5.2 I Technical specifications"), with a 30 mA
dedicated differential circuit breaker (circuit breaker or switch).
• Additional protection may be required during installation to guarantee the II overvoltage category.
• The electricity supply must correspond to the voltage indicated on the device's information plate.
• The electricity supply cable must be insulated against any cutting or hot elements that may damage or crush it.
• The equipment must be securely connected to a reliable earthing/grounding circuit.
• The electrical connection lines must be fixed.
• Use the gland provided to pass the supply cable into the device.
• Used the supply cable (H07RN-F type) adapted for outdoor or buried use (or run the cable into a protection duct) with
an external diameter of between 9 and 18mm.
• 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.
• Connect the supply cable to the connection terminal unit inside the device. On three phase models, there is no live
order to be respected.
