Note: Multi-rack feeders may have lugs
installed for bottom access which cannot
be repositioned due to insulator installed
in upper hole. Insulator can be moved to
bottom hole, and lug reinstalled in top hole
for top access. If for any reason lugs must
be moved they must be reinstalled with
the cup-shaped Belleville spring washers
supplied. Refer to Figure 1.
