Final Installation Checks
Chapter 6 provides a guide to help you run a final check of the 1302
Drive installation.
!
ATTENTION: Only qualified personnel familiar with
the 1302 Drive and associated machinery should
perform troubleshooting or maintenance functions on
the Drive. Failure to comply may result in personal
injury and/or equipment damage.
Perform the following checks of the Drive installation with the
power off:
!
ATTENTION: DC bus capacitors retain hazardous
voltage after input power has been disconnected.
Disconnect and lock out power to the Drive and wait
five (5) minutes for the DC bus capacitors to discharge.
Failure to disconnect power could result in death or
serious injury. Verify bus voltages using the procedure
in Chapter 9 before beginning any checks.
Step 1. Turn off, lock out, and tag the input power to the Drive.
Wait 5 minutes.
Step 2. Check the DC bus potential with a voltmeter as described in
Chapter 9 to ensure that the DC bus capacitors are
discharged.
Step 3. If an input disconnect is installed, make sure it is in the OFF
position.
Step 4. Make certain that all Drive interlocks installed around the
driven machine are operational.
!
ATTENTION: You must provide an external
emergency stop circuit outside the Drive circuitry to
remove AC line power to the Drive. This circuit must
disable the system in case of improper operation.
Failure to observe this precaution could result in
equipment damage, bodily injury or death. When AC
input power is removed, there will be a loss of inherent
regenerative braking effect and the motor will coast to
a stop. An auxiliary braking method may be required.
