•
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 protecti on and circuit breaking device (not supplied)
complying with the standards and regulati ons in force in the country where it is installed.
•
Electrical protecti on: via 30 mA residual-current circuit breaker.
•
The electricity supply must correspond to the voltage indicated on the device's informati on plate.
•
Use the power supply cable delivered with the appliance.
•
All extension cables or multi socket connects are prohibited. Request the installati on of a protected power socket near

2.3.1 Connecti ng an external command to supply the primary circuit
•
Use a 3G1 cable (secti on 1 mm²),
•
This functi 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 additi onal discharge “grommet” (supplied) to be installed
on the base of the box.
