Chapter 7 Final Check List Before Energizing
1.4.2 Is trained in the proper care and usage of protective
equipment such as rubber gloves, hard hat, safety glasses or face
shields, flash clothing, etc., in accordance with established safety
practices.
Perform the Pre-energizing
Check Procedure
1. Remove all blocks or temporary holding means used for
shipping all component devices in the MCC.
2. Inspect the enclosure and units for damage.
If structural damage is present, contact MCC technical support at
1.440.646.5800 and follow the prompts to Allen-Bradley>Low
Voltage Motor Control Centers>Post Shipment Support. If no
ATTENTION
To ensure the safety of personnel performing the pre-energizing
check, make sure the MCC remote power sources are
disconnected and locked in the OFF/O position.
Using a voltmeter, verify that the MCC remote power sources
are disconnected.
ATTENTION
Power factor correction capacitors (PFCCs) should be applied
correctly. For application instructions refer to
Power Factor
Correction Capacitors for Bulletin 2100 MCC Starter Units Application
Techniques,
publication 2100-AT001. When PFCCs are connected
to the motor circuit and the start-up procedure requires the
respective motors to be jogged, inched, or bumped (rotation
direction check), temporarily disconnect PFCCs. For more
information contact, Rockwell Automation LV MCC Technical
Support at 1.440.646.5800 and follow the prompts to
Allen-Bradley>Low Voltage Motor Control Centers>Post
Shipment Support.
ATTENTION
Verify that motor acceleration times are within specific
application specifications.
Excessive starting currents and/or acceleration times may
cause inverse time circuit breakers, power fuses, overload
relays, and other components to overheat and/or shutdown
equipment.
