CAUTION
After low voltage mode testing, ensure that the LV motor test resistor assembly is removed from each
phase arm before connecting the soft starter to a medium voltage motor. If the LV motor test resistor
assemblies remain on the phase arms, the soft starter may suffer severe damage.
CAUTION
After low voltage mode testing, any fan control wiring must be reconnected and the fan assemblies must
be screwed to the front of each phase arm before connecting to the medium voltage mains supply.
Medium voltage commissioning test

Check motor datasheets and motor terminal boxes to ensure that no capacitors are installed internally or cabled to
the motor terminal box.
Also check that no capacitors are directly connected to the soft starter's output.
Review the parameter settings for MV motor operation.
1. WARNING
Check that any non-conduction resistors or linking wires are removed from each phase
arm.
2. Set parameters according to the motor data and application requirements.
3. Program inputs and outputs according to the site requirements.
4. Connect the soft starter to the medium voltage supply, and connect the motor to the soft
starter. Do not connect motor to the load (ie leave the motor uncoupled from the load).
5. Use the soft starter to operate the motor and verify that the rotation meets the site
requirements.
6. Stop the motor.
7. Connect the MV motor to the load and use the soft starter to operate the motor.
8. Monitor parameters such as voltage, current, power. Calibrate voltage and current
readouts as required.
9. Once the customer is satisfied that the soft starter operates correctly, record all
parameter settings in the user manual (Section 6 Parameter Record). Take one copy of
the Parameter Record for supplier records (or fill in the sheet overleaf), and leave the
manual with the customer.
10. Use the Parameter Archive function to save the programmed settings as "User set 1".
