Troubleshooting
Before troubleshooting
Perform the following steps before starting any procedure
in this section:
• Disconnect AC line voltage from the drive.
• Check the drive closely for damaged components.
• Check that no conductive or other foreign material has
become lodged on the printed circuit board.
• Verify that every connection is correct and in good
condition.
• Verify that there are no short circuits or grounded
connections.
• Check that the voltage selection switch settings match
the AC line and output voltages.
• Check that the drive’s rated armature and field outputs
are consistent with the motor ratings.
• Check that the line fuses are properly sized and not
blown.
ATTENTION: This equipment is at line voltage when
AC power is connected. Disconnect and lockout all
ungrounded conductors of the AC power line before
working on the unit. Failure to observe this precaution
could result in severe bodily injury or loss of life.
