Inspect for Shipping Damage
Prior to continuing verifying the installation of the equipment, open the cabinets
to all equipment supplied by Rockwell Automation and inspect each component
installed for signs of damage. Make any damage claims to the Medium Voltage
Business as soon as possible in order to replace the damaged components as
quickly as possible.
See Publication 7000-IN008_-EN-P for further information on transportation
and handling.
Inspect Cabinets for Debris
Once you complete the safety checks and successfully isolated the drive line-up,
inspect all cabinets in the drive line-up for foreign material left behind during the
installation. Ensure that no tools, hardware or wiring debris remain in the drive.
Note that some electric components used within the drive create magnetic fields
that may attract residual metal shavings if the customer required any drilling or
metal cutting during the installation process.
Clear all metal shavings from the cabinet and take care not to get shavings into
the cabinets if you do any further drilling or cutting.
Protective Barriers
In confined spaces, installation electricians often remove protective barriers to
create more space within the cabinets. Ensure that you re-install all protective
barriers removed during installation. Failure to re-install a protective barrier may
result in equipment damage or personal injury.
Component Grounding
Verify that the drive and all its associated equipment have system power ground
cabling installed and that the cables are terminated at both ends. Terminate power
cable shield grounds at both ends. Ensure that all grounding hardware is
sufficiently torqued (see
Torque Requirements for Threaded Fasteners on
page 123 ). Ground all drive line-up components (drives, switcher, motors,
transformers and reactors) to the installation’s ground grid.
In drive line-ups supplied with isolation transformers, leave the secondary of the
isolation transformer floating so the drive line-up can reference system ground
from the upstream distribution transformer. Failure to do so may result in
unreliable drive operation.
