Short Term Storage

An installed control panel should have all openings sealed and the door properly latched in the
closed position. If power is left applied to the panel, internal devices will protect against normal
variations in outside temperature and humidity. If power is disconnected, the panel should be
stocked with desiccant material or an incandescent lamp to guard against condensation within the
panel.

If the control panel cannot be installed and powered without delay, proper precautions must be taken
to prevent damage due to corrosive atmospheres, water, humidity, dirt, dust, and physical damage.
The control panel should be stored in a climate controlled building. If a climate controlled building
is not available, desiccant bags or an incandescent lamp should be placed in the panel to guard
against condensation. Protect the panel by covering with a good canvas or heavy gauge plastic tarp
or similar covering material if stored outdoors.

Always disconnect and lockout all power sources to panel before working on or preparing for
storage.

WARNING

A warning tag must be attached to the face of the panel or secured to the locking

device

indicating power is supplied to the panel during storage.

Control panels are top-heavy. Once upright, control panels must be secured to

prevent

tipping (restated from warning label on inner door panel)

Long Term Storage

If the control panel is to be stored upon arrival at site, it should remain sealed within the crated box
or skid and stored in a climate controlled building that is maintained at or above ambient temperature
for the entire storage period. The control panel is shipped with corrosion inhibitors installed inside
and they have a life expectancy of 2 years provided temperatures do not exceed 104 degrees F (40
degrees C). Life expectancy is reduced by 25% above this temperature limit, which would still give
1 ½ years of protection. Corrosion inhibitors are installed for protection against salt and high
humidity. They eliminate pre-coatings, special wraps, and drying agents.

If the control panel has been installed outside and was operational and must be taken out of service,
it must contain some type of desiccant bags, drying agent, and/or corrosion inhibitors. The control
panel must also be covered with a good canvas or heavy gauge plastic tarp or similar covering
material to keep out dust, dirt, water, and foreign substances. If internal heaters are available inside
the panel, they are to be connected and energized for the complete storage period. If heaters are not
available, an incandescent lamp mounted inside the cabinet with an adequate power supply must be
installed. At all times during the storage period, the panel door must be kept closed, sealed securely,
and latched.
