• Incorrectly ghtened terminals may cause the terminal unit to heat up and invalidate the
warranty.
• Before any work inside the device, 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 qualifi ed and experienced technician is authorised to carry out cabling in the equipment
or to replace the supply cable.
• The exchanger's electrical supply must be provided through a protec on and circuit breaking device (not supplied)
complying with the standards and regula ons in force in the country where it is installed.
• Electrical protec on: via 30 mA residual-current circuit breaker.
• The electricity supply must correspond to the voltage indicated on the device's informa on plate.
• Use the power supply cable delivered with the appliance.
• All extension cables or mul socket connects are prohibited. Request the installa on of a protected power socket near
the appliance from an approved technician.
• If the supply cable is not long enough, it must be replaced by a qualifi ed technician.

• The equipment must be connected to an earth socket.
• The electrical connec on lines must be fi xed.
2.3.1 Connec ng an external command to supply the primary circuit
• Use a 3G1 cable (sec on 1 mm²),
• This func on is provided via the dry contact without polarity "normally open at rest" (maximum intensity 5A under
250Vac 50-60Hz) available on the terminal 19-20 regulator,
• The wire connected to terminals 19-20 must go through the addi onal discharge “grommet” (supplied) to be installed
on the base of the box.
