6.3 Wall duct insertion, ventilation unit connection cable
7. Electrical connection
The electrical connection must be implemented according to VDE 0100. For installation
and maintenance work, all poles must be disconnected from the mains with a contact opening width of
at least 3 mm. The mains disconnection must be secured against reconnection!
Insert the connecting cable (min. J-Y(ST)Y 2x2x0.6 mm²)
above (right / room-side view) into the wall duct.
Allow the connection cable protruding in the
length of the
wall duct.
Close the wall duct on the interior and exterior side using the
supplied wall covers, in order to prevent contamination of the
wall duct.
The AIRUNIT control unit must be connected as a stationary device with permanently installed lines.
The supply voltage of the AIRUNIT control unit is 230 V/50 Hz , a sheathed cable 3 x 1.5 mm²
(e.g. NYM-J 3 x 1.5 mm²) is recommended as a supply line.
The ventilation units are controlled by 12 V direct voltage (DC) , the ventilation units may therefore never
be connected to the 230 V mains voltage of the control electronics. As connecting cable for the AIRUNIT GEMINI
ventilation units we recommend a cable min. J-Y(ST)Y 2x2x0.6 mm² up to a connection length of 30 metres. Infor-
mation on installation and electrical connection can be found in the installation and operating instructions.
