Power Factor Correction
Power factor correction capacitors should be selected based on the motor data and
the required final power factor.
If power factor correction capacitors are being used, select a contactor according to
the required kVAr. The contactor must be connected on the supply side of the soft
starter. The power factor correction capacitor contactor coil is associated with
output terminals 33, 34 of the soft starter's power interface PCB.
To ensure that the potentially dangerous medium voltage area is isolated from the
low voltage control area, power is supplied to the power factor correction capacitor
contactor coil from the control voltage terminal block (refer to
Diagram 4: Internal
Wiring
on page 21).
NOTE
The capacitor bank must be fed from the supply side of the soft starter.
5.7 Line
Inductors
Line inductors are required if the cable run between the soft starter and the motor
is greater than 200 m. Line inductors should be installed outside the panel,
between the soft starter output (terminals T1, T2, T3) and the motor. Contact your
local supplier for selection details.
5.8
Transient/ Overvoltage Protection
Overvoltage protection should be installed if there is a risk of high transients at the
installation. If required, use the optional Overvoltage Protection Kit. Contact your
local supplier for details.
