Outdoor Equipment
The recommended procedure for installing a switchgear equipment
supplied in an outdoor enclosure is as follows:
1. POSITION THE EQUIPMENT-Position the equipment or sections
of equipment in their final location. If the equipment line-up
was split into two or more shipping sections, it is necessary to
first match, line up, and reassemble the multiple sections into
one integrated equipment.
2. APPLY GASKET MATERIAL-After removal of the lifting plates
(see Fig. 4-6), it is necessary to apply the self adhesive gasket
material (6), Fig. 4-17, to the mounting surface of the roof
flange (5). The gasket material is supplied with the equipment.
3. ALIGN SECTIONS-Align the two sections with the mating
surfaces butted together.
4. FASTEN SECTIONS TOGETHER-Referring to Fig. 4-17, the
mating sections of the outdoor enclosure should be
immediately bolted together including the front (3) and rear (4)
vertical posts and the roof flange (5). Each vertical post will
require ten 3/8-16 x 1-inch bolt assemblies; the roof flange
will require either eleven or twelve 3/8-16 x 1/2-inch bolt
assemblies. The bolts should be tightened with a torque of
25-30 ft-lbs. Figure 4-18 is a cross-sectional view of the
assembled roof joint.
