Checking the Power
Modules with Input Power
Off
Use the following procedure to check the Power Module circuitry of the drive
with power off.
1. Turn off and lock out input power. Wait 5 minutes.
2. Verify that there is no voltage at the input power terminals of the drive.
3. Check the DC bus potential with a voltmeter to make sure that the DC
bus capacitors are discharged.
ATTENTION: The parameters in the Device Items menu must be set by a
qualified person who understands the significance of setting them accurately.
Failure to observe this precaution could result in bodily injury.

ATTENTION: DC bus capacitors retain hazardous voltages after input power has
been disconnected. After disconnecting input power, wait 5 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.
