2-3 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 protective coverings to prevent
dirt, water, or other foreign substances from entering the
switchgear.
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.
ATTENTION: Enlever tous les cartons, contenants et tout autre
objet varié servant à l’emballage et au matériel d’emballage de
l’intérieur des sections du dispositif de commutation avant de
procéder à la mise sous tension de tout radiateur interne. Pour
éviter un incendie, enlever tout résidu de plastique ou de
polyéthylène des sections du dispositif de commutation avant de
procéder à la mise sous tension de tous les radiateurs internes.
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.
CAUTION: If the space heaters are to be temporarily energized
from external source, it is important to remove the fuses on the
secondary side of the control power transformer. This
precaution is to prevent a feed back of higher voltage to other
portions of the equipment through the CPT primary.
ATTENTION: Il est important de retirer les fusibles du côté
secondaire du contrôle du pouvoir du transformateur si les
espaces des radiateurs doivent être temporairement mis sous
tension par une source externe. Cette précaution prévient une
rétroaction d’un voltage supérieur à d’autres portions de
l’équipement par le contrôle de pouvoir du transformateur
primaire.
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.
