Electrical connection

DANGER due to electric shock.

Switch off the mains fuse before working on the electrical equipment. Observe safety instruction supplementary sheet.

DANGER due to short circuit/fire if moisture penetrates into the terminal compartment. Electronics cover not flat/tight if installed incorrectly.

Lead the cable sheathing into the terminal compartment as little as possible and sealed. Observe the permissible length of individual cable cores.

  1. Switch off mains fuse, secure against being accidentally switched back on and position a warning sign.
  2. Only lay single cable cores in the fan. To do this, remove power cable sheathing over a length of 100 mm. Strip single cable cores to 9 to 10 mm.

Circuit diagram

  1. Connect power cable to spring terminal → ECA 100 ipro circuit diagrams.

The standard model of ECA 100 ipro can be operated in two levels with double switches. Without a double switch, the fan can be operated either at power level 1 or at power level 2 → Associated switching variants Appendix.

  1. Check fit/tightness of the cable grommet.
  2. If necessary, connect a speed controller (STX 1,5).

The technology used in the phase angle controller may cause humming noises.
