Receiving, Handling & Storage
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 connec-
tions.
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.
3.
Protect equipment and external items from damage during
movement. Be sure to have smooth, unobstructed sur-
faces 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. Interunit bus
supports and bus joint boots should be removed using
side, rear and front access options as required. Note the
mounting position and orientation and save hardware for
use in reinstallation.
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, shipping pallets 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
switchgear bottom with support timbers and move with
jacks and rollers just to the side of its final position.
Remove rollers, shipping pallets and other packaging
materials and remove jacking facilities. Clear any obstruc-
tions. The equipment may be slid sideways up to 6 inches
(152mm) 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 distrib-
ute the force across the full depth of side. See Figure 4.

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 resis-
tant nor drip resistant. Therefore, it should be stored indoors. If
it is to be kept in a humid or unheated area, provide an adequate
covering and place a heat source of approximately 500 watts
output within each vertical section to prevent condensation.
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. When batteries
are supplied, connect them to a charger.
Storage: Shelter-Clad Outdoor Switchgear
When it is necessary to store Shelter-Clad outdoor equipment
in a location exposing it to the weather, or in a humid location,
energize the space heaters provided within the sections and
make certain that louvers and vents are uncovered to allow air
to circulate. If at all possible, erect the aisle section and install
the switchgear at the permanent location even though it may
be some time before the equipment is used. If the equipment
cannot be erected at the permanent location immediately,
cover shipping splits to protect from the elements.
Regardless of what method of storage is used, remove the
aisle wall from in front of instrument panels to gain access to
the space heater circuit so that heaters can be energized.
Refer to wiring diagram drawing for space heater circuit con-
nections. Replace the aisle wall and seal from the elements, or
cover for protection from the weather. Connect batteries (if
provided) to a charger. Lubricate hinges, shutters, and other
moving parts.
Storage: Non-Walk-In Outdoor Switchgear
When it is necessary to store non-walk-in outdoor switchgear
in an area exposed to the weather or under humid conditions,
energize the space heaters provided and make certain that lou-
vers and vents are uncovered to allow air to circulate. If at all
possible, erect the switchgear at the permanent location even
though it may be some time before the equipment is used. If
the equipment cannot be erected at the permanent location
immediately, cover shipping splits to protect from the elements.
Access to the heater circuit is gained by opening the door to
the instrument panel compartment. Refer to wiring diagram
drawing for space heater circuit connections. Connect batteries
(if provided) to a charger. Lubricate hinges, shutters, and other
moving parts.
Storage: Type GMI Vacuum Circuit Breakers and Lift Truck
Vacuum circuit breakers, if not installed in their respective
switchgear compartments, must be stored indoors. Outdoor
storage of circuit breakers (other than inside their respective
switchgear compartments) is NOT RECOMMENDED.
If furnished, the lift truck for handling circuit breakers should
be stored indoors. The lifting mechanism can be damaged by
extended outdoor storage. For short term (30 days or less)
storage, the lift truck may be stored outdoors, provided that it
is adequately covered to protect it from the weather.
