Energizing the Equipment
Energize the Equipment
1.
Review any additional instructions supplied for the proper operation of
special units such as variable frequency drives and soft starters with
appropriate and qualified personnel.
2.
Check that there is no load on the MCC when it is energized.
3.
De-energize all main and unit disconnect devices.
4.
Check to see if any associated remote devices are de-energized.
5.
Energize the MCC remote power source.
6.
Energize the main devices followed by the feeder devices and the branch
circuit devices.
Always energize from the source of the system, working towards the loads.
7.
After all of the disconnects have been closed, loads such as lighting circuits,
motor starters, and contactors may be energized.
ATTENTION:
This procedure is provided as general guidance for
energizing a newly installed CENTERLINE MCC and should be used after
the Final Check procedure has been completed. See
for more information.
ATTENTION:
Energizing a MCC for the first time is potentially dangerous.
Serious damage and or personal injury can result when power is applied.
Therefore, only qualified personnel should energize the equipment.
ATTENTION:
When working on or near energized electrical equipment,
follow established electrical safety-related work practices. Refer to NFPA
70E Standard for Electrical Safety in the Workplace.
ATTENTION:
The disconnect-device handles should be operated
with a firm, direct motion. Handles should not be ‘teased’ into the
closed (ON/I) position.
