9.1 Electrical connection accessories
The following wiring diagrams show the electrical connections between accessories and
fans (with EC motor) or frequency converters (e.g. FRQ, FRQS, FXDM) which can be
controlled with a 0–10V signal. If you are not sure if your fan is equipped with an EC- motor
please see chapter 6 Name plate and type key, page 8.
