Caution
Do not connect any capacitors to the output terminals of the soft
starter. If you do, the soft starter will be damaged.
Active filters, e.g. for reactive power compensation, must not be
operated in parallel while the motor control device is operational.
If capacitors for reactive power compensation are used, they must be connected
on the line side of the device. If a contactor disconnector or a main contactor is
used in combination with the electronic soft starter, the capacitors must be
disconnected from the soft starter when the contactor is open.
The SIRIUS 3RW44 soft starter is supplied with two different connection types:
• Screw-type connection
• Spring-loaded terminals
Two control voltage versions are available:
• 115 V AC
• 230 V AC
