Installation & Operation
2. Equipment designed for outdoor exposure
may be stored either in indoor or outdoor
storage locations. The equipment must
be protected from airborne external
contaminates if stored outdoors. Outdoor
storage will also require additional care
to maintain temporary covers over
the openings and shipping splits. The
equipment must be provided with control
power to facilitate the energization of
space heaters, as well as other temperature
and humidity controlling equipment. The
temperature should be kept above freezing
(>33°F/1°C) and below (<140°F/60°C). The
relative humidity should be kept below
60% or a dew point of 15°C/59°F. The
equipment should be stored in such a
manner as to leave all doors and panels
accessible for inspection. The equipment
must be inspected on a routine basis to
assure its integrity.
3. The auxiliary control devices, ship loose
material and protective relays must also
be protected. This includes items such as
battery chargers, UPS systems, lighting,
installation hardware and air conditioning.
If prolonged storage is anticipated,
humidity controlling desiccant materials
should be utilized. Desiccant packets
should be installed in all compartments and
packing containers.
