Storage
Switchgear
If it is necessary to store the switchgear equipment for any
length of time, the following precautions should be taken to
prevent corrosion or deterioration.
1.
Remove protective covering. Check thoroughly for
damage.
2.
Store in a clean, dry, rodent-free location with
moderate temperature and provide coverings to
prevent dirt, water, or other foreign substances from
entering the switchgear.
3.
If dampness or condensation may be encountered in
the storage location, heaters must be placed inside
the switchgear sections to prevent moisture damage.
Approximately 250 watts of heat in each section is
required. On outdoor switchgear equipment, this
may be accomplished by making a temporary power
supply connection to the heaters already installed in
the equipment. On indoor switchgear, factory
installed heaters are available as an option.
4.
If the switchgear is to be used with an external
exhaust plenum system, be sure that the factory
installed temporary covers are in place for storage.
Equipment shipped from the factory without the
external exhaust plenum will have covers located on
each vertical section on the top of the plenum flange
assembly (Figure 2.8).
CAUTION: Remove all cartons, containers and any
other miscellaneous packaging and packing material from
inside the switchgear sections before energizing any
internal heaters. To prevent fire, remove any plastic or
polyethylene shrouding from the switchgear sections
before energizing any internal heaters.
CAUTION: If the space heaters are to be temporarily
energized from an external source, it is important to
remove the fuses on the secondary side of the control
power transformer. This precaution is to prevent a
feedback of higher voltage to other portions of the
equipment through the control power transformer primary
circuit.
Circuit Breakers
If circuit breakers are not to be placed into service at once,
remove them from their shipping cartons and thoroughly
inspect them for damage. If the breakers are in satisfactory
condition, replace the breakers in their shipping cartons for
storage. Do not remove the circuit breaker shipping members
at this time.
Store the circuit breakers in a clean, dry location in an upright
position. They must be properly supported to prevent
bending of the studs or damage to any of the breaker parts.
Do not remove any protective grease until the circuit breakers
are ready to be installed. A plastic or canvas-type cover
should be provided to reduce the possibility of damage to the
breakers due to dust and water.
Exhaust Plenum Components
If it is necessary to store the exhaust plenum system for any
length of time, the following precautions should be taken to
prevent corrosion or deterioration.
1.
Remove protective covering. Check thoroughly for
damage.
2.
Store in a clean, dry, rodent-free location with
moderate temperature and provide coverings to
prevent dirt, water, or other foreign substances from
entering the individual components.
