Temporary storage
If the switchgear will not be immediately installed upon
receipt, it should be stored under the following conditions
to avoid damage:
-
Unpack immediately upon delivery and inspect for
damage. See Receiving.
-
Open all section doors and allow the equipment to
adjust to room temperature and humidity for several
hours.
-
Store the equipment in an area where the ambient
temperature remains above 16°C (60°F) but will not
exceed 65°C (149°F). The air must be dry (50% moisture
maximum).
-
Before energizing the space heaters remove all packing
materials from the SG.
-
Connect external power to space heaters (and
temporarily disconnect from internal circuitry, if so
connected) adjusting the thermostat between 35°C
(95°F) and 40°C (104°F) to help drive off condensation.
-
Do not omit the use of appropriate personal protective
equipment (PPE) necessary to do the connections of the
power supply of the heaters.
-
If the switchgear will not be installed soon after arrival,
cover the sections to protect them.
-
During the operation of the heaters, these must be
monitored to avoid any damage that may cause a fire.
-
Check once per week for condensation on the
components. If condensation is detected, dry the
equipment and move it to a different storage area.
TIP:
You can use heaters or hang a 100 watt incandescent
light bulb inside the section to reduce condensation.
If your delivery includes spare parts:
-
Store the components indoors in a condensation- free
environment, with no more than 50% humidity, with
ambient temperature above freezing but not exceeding
104°F (40°C).
-
Store them with the boxes top-side up.
-
Store circuit breakers upright in their original shipping
carton. Do not stack.
