Installation and Start-Up Guidelines 4-7
Step 1. If the drive is powered up, disconnect and lock out all incoming AC line/DC
bus power and control power to the drive. Refer to section 4.7.1 for additional
information on measuring and discharging DC bus voltage.
If the drive is not under power, proceed to step 2.
Step 2. Visually check that the AC line supply or DC bus supply to the drive is of the
correct voltage, frequency, and polarity, and that the plant supply branch
from which the drive is to be operated is of sufficient ampacity to supply drive
input current requirements.
Step 3. Check that the AC line transformer (if used) is connected to provide the
correct phases and voltages to the inputs of the drive.
Step 4. Verify that all drive components have been properly installed and interwired
per the instructions provided in the wiring diagrams (W/Ds, W/Es, W/Ls,
W/Os, and W/Is).
Step 5. Open the drive’s cover or enclosure door. Inspect the interior of the drive for
cables that may have come loose during shipping. Re-secure the cover or
enclosure door.
Step 6. Check for grounds in the magnetic control circuits. Always use an ohmmeter
to check for grounds in resolver circuits.
Step 7. Check rotating equipment for grounds.
Step 8. Check for tight connections on all wiring.
Step 9. Check circuit breaker trip settings.
Step 10. Verify that all safety devices are in place. Test the mechanical door interlocks
on the power cubicles to ensure they are operational.
!
ATTENTION:After disconnecting input power, wait five (5) minutes for
the DC bus capacitors to discharge. Then check the voltage across the
DC bus to ensure the bus capacitors are discharged before touching any
internal components. Failure to observe this precaution could result in
severe bodily injury or loss of life.
