Troubleshooting the Drive 12-19
12.7 Common Symptoms and Corrective Actions
!
ATTENTION:Remove power from the drive. DC bus capacitors retain
hazardous voltages after input power has been removed. After
disconnecting input power, wait five minutes for the DC bus capacitors
to discharge and then check the voltage with a voltmeter to ensure the
DC bus capacitors are discharged before touching any internal
components. Failure to observe this precaution could result in severe
bodily injury or loss of life.
