Commissioning the Drive Chapter 5
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
). 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.
Information on Splice Kits
If the drive line-up was shipped in sections, verify that the bus splice kits provided
in this circumstance are properly installed and torqued at shipping split locations.
Power Cabling
Ensure that all customer power and control wiring required for drive line-up
installation are identified on the electrical drawings by a dashed line (see your
electrical drawing’s General Notes for additional information).
ATTENTION: Power cabling should be installed in accordance with local codes
and guidelines. The information in this section is to be used as reference only
and is not intended to replace practices outlined in the electrical code.
