level floor surface requirements.
1) Position the left side section on a level surface and secure the
section in place with ½ in. (M12) floor mounting bolts (Refer to
Anchoring, page 2-4).
2) When joining NEMA/EEMAC Type 12 sections, apply a
continuous 1/8-in.- (3-mm-) wide bead of silicon sealer around the
perimeter of one section.
3) Remove the side bus access covers if applicable.
4) Position the right section against the left section. Ensure that the
surface is level.
5) Secure the sections together using the 1/4-20 self-tapping screws.
Thread the screw through the 0.281 in. clearance hole to the
corresponding 0.219 in. pilot hole. To access the front clearance
holes of the left-side cabinet, open the medium voltage doors. To
