Electrical connection

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

  1. Insulate any unnecessary cable cores.
  2. Do not touch electric components.
  1. Only lay single cable cores in the unit. To do this, remove power cable sheathing over a length of 40 mm. Strip single cable cores to 5 to 6 mm.
  2. Electrically connect the fan supply lines, sensor connection cable and power cable according to the circuit diagram, see also the circuit diagram in the chapter Wiring diagrams and in the cover of the unit.

The power supply for connected fans is switched simultaneously at the "Supply air" and "Exhaust air" terminals. This means that both terminals can be used for both supply air and exhaust air fans.

  1. Check the fit of the electrical connections.
  2. Fasten the cover with 4 screws.
