WARNING! ACA 635 must be supplied with a transformer dedicated to
drives and motors or equipment of equal or higher power, or with a
transformer equipped with two secondary windings, one of which is

capacitive load (e.g. lighting, PC, PLC, small power factor
compensation capacitors) in the same network with ACA 635. The
resonance current might damage some unit in the network.
