Inspect or Replace HECS
Two current sensors are located at the top inside the Power Module Cabinet.
Verify that the current sensor wire connector is properly seated. Check for
obvious signs of damage.
1.
Unplug the Current Sensor Connector from the HECS.
2.
Disconnect one end of the power cable that goes through the HECS from
the Power Module.
3.
Remove the Mounting Bracket with the HECS still attached.
ATTENTION: To prevent electrical shock, disconnect the main power before
working on the drive. Verify that all circuits are voltage-free, using a hot stick or
appropriate high voltage-measuring device. Failure to do so may result in injury
or death.
