I Electricity Supply Connecti Ons - Zodiac Z900 TD20 Instructions For Installation And Use Manual

1.3 I Electricity supply connecti ons

• Incorrectly ti ghtened terminals may cause the terminal unit to heat up and invalidate the
warranty.
• Before any work inside the device, you must disconnect the electricity supply to avoid the risk
of electric shock which may cause material damage, serious injury or even death.
• Only a qualifi ed 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 properly selected and rated and circuit breaking device
(not supplied) complying with the standards and regulati ons in force in the country where it is installed.
• The device is provided for connecti on to a general power supply with a TT and TN.S neutral regime.
• Electrical protecti on: by circuit breaker (D curve) (for calibre, see § "5.2 I Technical specifi cati ons"), with a 30 mA
dedicated Ground Fault Circuit Interrupter (GFCI).
• Additi onal protecti on may be required during installati on to guarantee the II overvoltage category.
• The electricity supply must correspond to the voltage indicated on the device's informati on plate.
• The electricity supply cable must be protected from any damage such as sharp edges, abrasion, excessive heat that
may damage or crush it.
• The equipment must be reliably connected to an appropriate earthing (grounding) point.
• The electrical connecti on lines must be fi xed.
• Use the gland to pass the supply cable into the device.
• Use the supply cable (RO2V type) adapted for outdoor or buried use (or run the cable into a protecti on duct) with an
external diameter of between 16 and 22mm.
• We recommend burying the cable at a depth of 50 cm (85 cm under a road or path) in an electrical duct (ribbed).
• If this buried cable meets another cable or pipe (communicati on, gas, water, etc.), there must be more than 20 cm
between them.
• Connect the supply cable to the connecti on terminal unit inside the device.
• Check that the phases are in the right order: the LED on the phase order controller (RSF) must
be on fi xed.
