INSTALLATION: SETUP TOOLS

For V06 and V07 units:
Clip one end of the resistor assembly to the plated hole on the non-conduction
PCB. The non-conduction PCB is located on the side of the phase arm, at the
top of the long round grading resistor (on the right hand side when viewed from
the front). There is a small steel bracket just in front of the PCB. Pass the
other end of the resistor assembly through the phase arm, in front of the three
grading resistors, and clip it to the steel bracket in front of the grading resistor
on the other side of the phase arm (this bracket looks the same as the bracket
in front of the non-conduction PCB).

3. Connect T1, T2, T3 of the soft starter to a three phase motor with full load
current greater than 5 A. Connect L1, L2, L3 of the soft starter to three phase
mains supply with voltage less than 500 VAC (frequency 50 Hz or 60 Hz).
4. Set parameter 1-A Motor Full Load Current to the value shown on the motor
name plate. Set parameters 3-U Overvoltage Level and 3-W Undervoltage
Level to suit the low voltage mains supply.
5. Switch on control and mains supply, and use the MVS to start the motor. The
start command can be sent from the MVS Controller or via the remote input.
Monitor the soft starter's display and verify the line voltage readings.
6. Stop and restart the motor several times to confirm correct and consistent
operation.
7. When testing is complete, isolate the soft starter from the mains supply.
Disconnect the soft starter from the motor and mains voltage, then remove
control voltage. Remove the non-conduction resistor assembly from each
phase arm.
WARNING
After low voltage mode testing, ensure that the non-conduction resistor
assembly is removed from each phase arm before connecting the soft
starter to a medium voltage motor. If the non-conduction resistor
assemblies remain on the phase arms, the soft starter may suffer severe
damage.
