Installation Review
Prior to commencing the commissioning of the drive line-up it is
recommended that the installation of the equipment be re-inspected.
Identifying errors in the drive installation prior to commencing the
commissioning as opposed to mid way through the commissioning
process will greatly reduce the amount of time required to
commission the drive line-up.
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. Any damage
claim should be made back to the Medium Voltage Business as soon
is it is identified so the damaged components can be replaced as
quickly as possible.
Inspect Cabinets for Debris
Once the safety checks have been completed and the drive line-up
has been successfully isolated, inspect all cabinets in the drive line-
up for foreign material left behind during the installation. Ensure that
no tools, hardware or wiring debris have been left in the drive. Note
that some electric components used within the drive create magnetic
fields that may attract metal shavings left behind if drilling or metal
cutting was required during the installation process. Ensure that all
metal shavings have been removed from the cabinet and take care
not to get shavings into the cabinets if drilling or cutting is required
during drive installation.
Protective Barriers
In confined spaces, it is common for the electricians responsible for
the installation to remove protective barriers to allow for more space
within the cabinets. Ensure that all protective barriers removed during
the installation have been re-installed. 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. Power cable shield grounds are to be terminated at both
ends. Ensure that all grounding hardware is sufficiently torqued (See
Appendix B "Torque Requirements"). All drive line-up components
(Drives, Switcher, Motors, Transformers and Reactors) must be
grounded to the installations ground grid.
In drive line-ups supplied with Isolation Transformers, it is important
to 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.
