DANGER Danger to life from electric shock.

DANGER Danger from electric shock/The unit will be damaged if installed incorrectly with too long a power cable.

If the cable feed is too long inside the housing, the fan insert cannot be installed correctly. The power cable may be damaged when inserting the fan unit.

NOTICE Risk of damage if ESD sensitive components on the board are touched.

Avoid direct touching of the components or contact surfaces.

NOTICE Damage to the unit if connected incorrectly.

For example, if an electric load is connected to terminal 4 or if connected to 2 phases.

NOTICE Risk of damage to unit in the event of short-circuits.

Always note the relevant specifications for electrical installations and when fitting equipment. In Germany, observe DIN VDE 0100 and the corresponding parts in particular. In rooms with baths or shower units, for example, this would be Part 701.

  1. Switch off mains fuse, secure and fit warning sign.
  2. Remove power cable’s sheathing and cut to length as described.
  3. Cut off and insulate PE conductor and individual cable cores that are not required!
  4. Make electrical connection according to wiring diagram on terminal box: Wiring diagrams.
