I Electrical Connections - Zodiac Red Line 3 Installation And User Manual

2.3 I Electrical connections

2.3.1 Voltage and protection
• The power supply to the heater 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 electrical connection lines must be fixed,
• Use the gland to pass the power cord into the appliance.
Electrical protection: via a dedicated 30 mA residual-current circuit breaker (circuit breaker or switch)
Acceptable variation in voltage: ± 10% (during operation)
2.3.2 Connections
• Incorrectly tightened terminals may cause the terminal unit to heat up and invalidate the
warranty.
• The appliance must be connected to an earth socket.
• Risk of electrical shock inside the appliance.
• Only a qualified and experienced technician is authorised to carry out cabling in the appliance.
• If the power cord is damaged, it must be replaced by a qualified technician.
• The power cord must be insulated against any cutting or hot elements that may damage or crush it,
• Check that the power cord is firmly attached to the connection terminal board.
12 kW Red Line units are wired via three-phase systems only.
3, 6 and 9 kW Red Line units are pre-wired for supply via a single-phase system when leaving the
factory.
To switch to a three-phase supply:
- Detach the label from the terminal block,
- Remove the 2 bridging straps (
- Reattach the label after pivoting it by 180° from its original position.
Single-phase
2.3.3 Cable sizes
• Power cord size: for cables of a maximum length of 20 metres (calculation basis: 5A/mm²), this must be
checked and adapted depending on the installation conditions.
