Chapter 4 Installing and Removing Plug-in Units
For the CENTERLINE 2100 MCC units with arc-resistant door
latches, you may need to tilt the top of the unit slightly to the
rear to avoid interference with the top arc latch bracket before
removing the unit. If you do not have enough clearance, you
will need to loosen the latch bracket screw (approximately two
turns) to remove the unit.
10. Remove the unit from the MCC.
11. Carefully install protective caps or close manual shutters after
the unit is removed.
Automatic shutters will close as units are removed.
TIP
For dual-mounted, fusible-feeder disconnect switch units,
you will need to remove the bottom arc latch bracket. You
can do this by first removing the unit located below the
dual disconnect unit.
ATTENTION
All covers and doors must be in place before applying
power to the MCC. If units are removed, they must be
replaced with the appropriate items such as units,
doors, and unit support pans.
