Electrical connection

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

  1. Insulate PE conductor and individual cable cores that are not required.
  2. Do not touch electric components.

Master-slave operation of RC units is only possible with similar types of ECA 150 ipro RC/RCH/KRC/KRCH units.

  1. Only lay single cable cores in the fan. To do this, remove the power cable’s sheathing in the terminal compartment. Strip single cable cores to 9 to 10 mm.
  2. Connect power cable to the spring terminal → .

The standard model of ECA 150 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 → switching variants in chapter .

  1. Check the position of the cable grommets. These must provide a good seal.
  2. If necessary, connect a speed controller (STX 1,5).

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