4.4.2 - DETAIL OF THE CONNECTION
• Remove the cover of the electrical box.
• Cable clamps are provided to maintain the cable at their
entry point into the box.
• Connect the cables to the terminals provided.
• Make sure that the wires are correctly connected to the
terminals. Incorrect connection can cause operating
problems as well as overheating which can cause
fi res.
• When replacing the box's cover, be sure not to pinch
the cables.
4.4.3 - POWER SUPPLY
• 230V / 1+Earth / 50Hz power supply from a power supply and protection device (not included) in accordance with with
the rules in force. The protection must be ensured by a two-pole circuit breaker (not supplied).
Note: The unit is designed to be connected to a power supply having a TT neutral regime (neutral to ground) or TN.S
regime (to neutral) as per NF C 15-100.
For a IT neutral point connection (isolated
neutral), provide ground fault protection.
• The acceptable voltage variation is ± 10% during
operation.
• Wire sizes are given for informational purposes only.
Wire sizes must be checked and adapted, as required,
according to the installation conditions and with regard
to current standards.
• The power supply is connected to terminal strip X1
(terminals U, N, and PE) of the printed circuit board
located in the electric box (see drawing opposite).

Note:
• The electric heating power supply can be supplied
separately. In this case, remove the power jumper
between terminal strip X1 of the printed circuit
board and the heating power supply terminal
strip.
• The heating power supply cable is thus connected
