Commissioning
Introduction This chapter provides guidance for the startup of a newly installed MCC.
We recommend that you make an itemized list that includes the following:
• Serial number
• Number of columns
• Number of units and their corresponding voltage
• Current ratings
• Kilowatt ratings
• Types of circuits
• Fuse sizes
• Circuit breaker ratings and trip settings
• Other important data
This itemized list should be saved in a file along with other data for the MCC
such as, component manuals, MCC manuals, overload relay instructions and
wiring diagrams.
Pre-commissioning Checklist
ATTENTION: Follow applicable company safety procedures.
ATTENTION: To protect the safety of personnel performing the pre-energizing
check, verify remote MCC power sources are disconnected and locked in the
OFF/O position. Follow local codes and guidelines in addition to the
requirements of EN 50110.
Use a voltmeter to verify that the remote MCC power sources are disconnected.
ATTENTION: Power factor correction capacitors (PFCCs) must be applied
correctly. 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 additional assistance, contact your Rockwell Automation representative.
