Electrical Connection - Opera Nivel Pro Installationshandbuch

3.9 CONTACT WITH WINDOW SWITCH
The control of your OPERA blower is equipped with a window contact circuit. If the contact
loop of the controller is interrupted, the power supply to the blower is interrupted. The OPERA
induction hob keeps working, but the extractor hood operation is deactivated and the hood
touch control blinks.
The window contact is mandatory in Germany
Only window contact switches approved by DIBt (Deutsches Institut für Bautechnik) may be
connected potential-free to the contact loop.
The contact must be closed when the window is open!
(pressure switch not actuated = closed) (reed switch ope in magnetic field)
The connection cable is fixed to the unit surface with a label.
WARNING
Please have the execution confirmed by the specialist company after the installation
has been completed!
