Reactive power compensation
Capacitors for improving the power factor (reactive power compensation)
Capacitors may not be connected to the output terminals of the 3RW52 soft starter.
Connecting capacitors to the output terminals will damage the 3RW52 soft starter.
Active filters, e.g. for reactive power compensation, must not be operated parallel to the
motor control device.
If capacitors are to be used to correct the power factor (actively or passively), they must be
connected on the line side of the device. They must not actively control the power factor
during the starting and coasting down phases. If a contactor disconnector or main contactor
are used together with the electronic 3RW52 soft starter, the capacitors must be
disconnected from the 3RW52 soft starter when the contactor is open.

Electromagnetic compatibility (EMC) according to IEC 60947-4-1
This product is designed for Environment A. It may produce radio interference in domestic
environments, in which case the user may be required to take adequate mitigation
measures.
