Physical Inspection
•
Check for any visual/physical evidence of damage or
degradation of components in the low voltage
compartments.
–
This includes relays, contractors, timers, terminal
connectors, circuit breakers, ribbon cables, control
wires, optional UPS, AC/DC power supplies, and so
on. Causes could be corrosion, excessive
temperature, or contamination.
•
Check for any visual/physical evidence of damage or
degradation of components in the medium voltage
compartments (cables, contractors, circuit breakers,
isolation disconnecting blades, power units, and so
on).
–
This includes main cooling fan, power devices,
heatsinks, circuit boards, insulators, cables,
capacitors, current transformers, potential
transformers, fuses, wiring, and so on; Causes
could be corrosion, excessive temperature, or
contamination.
•
Clean all contaminated components using a vacuum
cleaner (DO NOT use a blower), and wipe clean
components where appropriate.
•
Conduct the physical inspection and verification for the
proper operation of the contractor/isolator interlocks,
and door interlocks.
•
Conduct the physical inspection and verification for the
proper operation of the key interlocks.
•
Conduct the cleaning of the fans and verify that the
ventilation passages are not blocked and the impellers
are freely rotating without any obstruction.
•
Conduct the insulation resistance (IR) test on the
transformer, motor, and associated cabling.
•
Check all bolts for fastening and adjust them as
necessary.
•
Check all labels for readability. If any labels are
unreadable, damaged, or missing, contact Rockwell
Automation for replacements.
