Removal 1. Turn off all power supplying this equipment before working on or inside
the equipment, and follow lockout/tagout procedures. Always use a
properly rated voltage sensing device to confirm the power is off.
2. A captive rivet at the bottom of each bus barrier panel secures the
panels to mounting brackets on the MCC (see Figure 132 below, and
Figures Figure 133 and Figure 134 on 116).
3. Firmly grasp the head of the left side rivet and pull until the rivet releases
from the mounting bracket.
4. Pull out on the bottom of the left side panel until the tab at the top of the
panel is clear of the top track (see Figure 133 on page 116).
5. Remove the panel from the MCC.
