Final Movement of Assembly
Proper final movement and connection of the assembly requires
that several items be completed.
1. Preplan sequence of installation movements and connections.
2. Where equipment must be slid into final location, start
with the left end shipping group and continue in sequence.
Secondary conduits which stub-up above floor level may
block sliding in either direction. End trim must be removed
before attempting slide units into place.
3. Protect equipment and external items from damage during
movements. Be sure to have smooth, unobstructed surfaces
where the equipment is to be slid. Keep access openings clear.
4. Prepare for the connections across shipping splits before the
equipment is moved into final position. Note the mounting
position and orientation of any items removed during install-
ation, and save hardware for use in installation.
5. Thread coiled wires across shipping splits into interunit wire
trough prior to moving equipment into its final position.
6. Where top lift capability is available, the shipping skid and
other packaging materials may be removed before the last
move into the final position.
7. Where top lift capability is not available, protect the switch-
gear bottom with support timbers and move with jacks and
rollers just to the side of its final position. Remove rollers,
shipping skid, and other packaging materials and remove
jacking facilities. Clear any obstructions. The equipment
may be slid sideways to join the shipping split. Any sliding
force must be carefully applied across the bottom 4 inches
(100mm) of the switchgear side with proper cribbing to
fully distribute the force across the full depth of side. The
end trim covers must be removed from the last section to
keep them from being crushed when sliding the equipment.
Replace end trim when gear is in it's final position. Watch
for conduit stubbing as equipment is slid into place. See
Figure 6.

8. Be sure to install roof channels on outdoor switchgear to
make the equipment weather resistant. See Figure 13.
9. See "installation" section for additional important information.
Storage-Indoor Switchgear
When switchgear is not to be installed immediately, it should
be unpacked, inspected within 15 days of receipt and stored in
a clean dry location. Indoor switchgear is neither weather resist-
ant nor drip resistant. Therefore, it should be stored indoors. If it
is to be stored outdoors, or in a humid, unheated area, provide
an adequate covering, and place a heat source of approximately
400 watts output within each vertical section to prevent con-
densation. Space heaters are not standard equipment on indoor
switchgear. Lubricate any moving parts such as hinges, shutters,
etc., if storage is for an extensive period of time.
Hazardous voltages.
Will cause death, serious personal injury or
property damage.
Before using external source to energize space
heaters, disconnect space heater circuit from normal
supply to prevent back-energization of control power
transformer.
Storage-Outdoor Switchgear
When storing outdoor switchgear in an area exposed to the
weather or to humid conditions, energize the space heaters
provided within the sections and make certain that louvers
and vents are uncovered to allow air to circulate. The heater
circuit is typically accessible by opening the rear door of the
switchgear. Refer to the switchgear wiring diagram to
determine where space heater connections can be made.
Lubricate any moving parts such as hinges, shutters, etc., if
storage is for an extensive period of time. Be sure to install
roof channels during storage to make the equipment weather
resistant. See Figure 13.
If the outdoor switchgear lineup consists of multiple shipping
groups, it is neither weather resistant or drip resistant and it is
strongly recommended that the equipment be stored indoors.
If it must be stored outdoors, an adequate covering must be
provided to protect the equipment from the weather.
