NOTICE
The roof is heavy. At least two line crew
are needed to remove the roof.
Step 16
For each module, remove the
¹⁄₂
13 hex-head
stainless-steel cap screws, lockwashers, and
fl at washers that attach the roof section to
the module. See Figure 9. Each roof section
will have two capscrews, two lockwashers,
and two fl at washers. In order to remove the
roof, grasp with both hands and pull forward
until it is stopped by the two neoprene rollers.
Then, push down on the roof so that the side
channels clear the rollers. Next, continue to
pull the roof forward—with the help of the
second person—until the roof section is clear
of the switchgear. See Figure 10.
