Fig. F + G: Connecting the fan

NOTICE: Risk of short circuits, damage to the unit due to water penetration if the power cable is inserted incorrectly into the terminal box. Guide the cables into the terminal box such that the cable grommet fits around the cable sheathing completely. If necessary, seal the cable grommet on site.

NOTICE: Risk of injury in case of incorrect mounting, if the fan falls down due to its inherent weight. The fan vibrates slightly. Only install in windows with a thickness of 3 to 30 mm and using enclosed mounting material.

EVN 22 R: Guiding the connection cable to the shutter

  1. Punch the cable grommet [T1] with a grommet puncher and insert it into the side of the terminal box.
  2. Guide the connection cable through the cable grommet [T1] and provide tension relief.

EVN 22, EVN 22 R: Routing the power cable

  1. Route the power cable to the installation site.
  2. Punch the cable grommet [T2] with a grommet puncher and insert it into the terminal box.
  3. Guide the power cable from above through the cable grommet [T2] and provide tension relief.

Connecting the fan electrically

  1. Connect the power cable to the terminal block and wire according to the circuit diagram (→ sticker in the terminal box or chapter Circuit diagrams). For EVN 22 R, also connect the connection cable for the shutter.
  2. Connect optional accessories.
  3. Fit terminal box cover and secure it with the two screws. Tighten the screws hand-tight.

NOTICE: Damage to the unit, due to moisture, if the terminal box cover is not properly fitted. Ensure that the seal is in the correct position and correctly seated.

Fitting the inner cover
