Electrical connection
The fans are delivered ready for installation and are equipped with an easily accessible motor terminal box. The electrical installation must be done in accordance with the valid provisions and observing the local regulations. A wiring diagram is included each engine, from which the correct connection of the motor can be seen. The motor connection is only carried out with shielded cable and may not exceed a total length of 10 m. The operating instructions of the electronic commutating unit must be observed.
Speed control
The infinitely variable speed input of the motor is done by connecting an external potentiometer (accessory) or an external 0-10 V / PWM signal.
