Maintenance
Establish a Maintenance
Program A periodic preventative maintenance program must be established for MCCs to
help avoid unnecessary downtime. At a minimum, checks must be made once a
year. If equipment within the MCC is subject to heavy duty or highly repetitive
operation, more frequent maintenance can be necessary. Use the following
suggested maintenance guidelines to establish a maintenance program.
Keep a log of service and maintenance work performed on your MCC. Record
the following information.
• Date test and maintenance work is performed
• List of checks and tests performed
• Condition of the equipment
• Any repairs and/or adjustments made to equipment
For maintenance regarding specific components, such as circuit breakers,
contactors, AC drives, relays, and meters, reference the specific component
instruction manual for each device.
ATTENTION: Only skilled personnel should oversee the maintenance
and servicing of motor control centers.
De-energize all power sources before performing maintenance or service
work on columns or units.
Follow local codes and guidelines in addition to the requirements of
EN 50110 when working on energized equipment.
Replace and secure all barriers, covers, shields and doors, and perform the
Pre-commissioning Checklist on page 67 before re-energizing the
equipment.
