Publication 2100-IN012B-EN-P - April 2005
3-2 Final Checklist 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.”
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. If no structural damage is
visible, the electrical spacings should be intact. Refer to Table 3.A and
Table 3.B for the required minimum electrical spacings (See page 3-6).
3. Check and verify that the MCC is properly installed, as described in
Chapter 2. Inspect and verify that it is level, supported and anchored (if
necessary or required).
ATTENTION
To ensure the safety of personnel performing the
pre-energizing check, make sure the motor control center
remote power source(s) is disconnected and locked in the
“OFF” / “O” position.
Using a voltmeter, verify that the motor control center
remote power source(s) is disconnected.
ATTENTION
Power factor correction capacitors (PFCCs) should be
applied correctly. For application instructions please see,
publication 2100-AT001x-EN-P. 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.
If problems arise, please contact Rockwell Automation
technical support.
ATTENTION
Verify that motor acceleration times are within specific
application specifications.
NOTE: 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.
