Safety Instructions
ACS 600 MultiDrive 5
ACA 635 (ISU) Supply
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
dedicated to drives and motors. Resonances might occur if there 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.
Supply Connections
The supply section is equipped with a disconnecting device. The
electric parts of the whole drive system can be separated by the
disconnecting device from the mains network for installation and
maintenance work. The supply disconnecting device must be locked to
the open position during installation and maintenance work. Both
disconnecting devices of 12-pulse units must be be locked to the open
position during installation and maintenance work.
