CENTERLINE 2100 Motor Control Center (MCC) Units with Vertical Operating Handles
Before You Begin
Follow this procedure before you begin installing your unit.
1. Remove all packaging material from the unit.
2. Read the unit installation instructions.
3. Familiarize yourself with the unit.
4. Inspect unit for shipping damage.
5. For SecureConnect™ units, verify that power stabs fully extend and retract.
ATTENTION: When installing units for CENTERLINE 2100 Motor Control Centers 
with ArcShield™ baffles, you must make sure you are installing a unit that has 
the same arc resistance rating as the MCC in which it is being installed. Units 
that are not rated for 100 ms arc duration must not be installed in a section that 
is rated for 100 ms arc duration. The arc resistant rating will not apply if that is 
done.
ATTENTION: SecureConnect units must be installed in Series P or later 
CENTERLINE 2100 Motor Control Centers. If installing a SecureConnect unit in a 
Series N or earlier MCC, you must have compatible bus covers installed. For more 
information, contact your local Allen-Bradley® distributor or Rockwell 
Automation sales representative.
