the mounting bracket that keep the polyester
phase barriers in their proper positions.
Step 7: Turn the load lug assembly 180° with the lugs
at the bottom and remount the assembly by
reversing the procedures described in Steps 5
and 6. The mounting bracket will now be bolted
to the bottom of the power panel. Make certain
that all glass polyester phase barriers are in
place and positioned properly in the grooves
provided. When making any bolted connection
to the bus, comply with the torque require-
ments as outlined in Table 4.1.

Step 8: Remount the operating mechanism to the front
of the power panel with the six bolts removed
previously in Step 4.
Step 9: Position the power panel in the enclosure such
that the two upper elongated holes, one on
either side of the power panel, fit over the two
positioning bolts located in the rear of the
enclosure. This will line up the four correct
mounting holes in the power panel with the pre-
tapped inserts in the rear of the enclosure.
Step 10:With the power panel held securely against the
back of the enclosure, replace and tighten the
four mounting bolts removed previously in Step 3.
Step 11:Attach the neutral strap to the back of the
enclosure through the upper bonding hole,
which may or may not have been previously
removed in Step 2.
Step 12:Reconnect the connector plugs and the trans-
fer switch equipment is now configured for bot-
tom entry.
