before
handling the controller(s).
FlexTrol™ are fabricated as rigid, floor-
mounted, self-supporting, steel unit
vertical section(s). They are shipped in an
upright position, and should be kept in an
upright position when received.
Note:
Any questions regarding equipment
handling should be referred to Powell.
When controllers are received, the purchaser
should check the material received with the
shipping list to ensure that all parts have been
included. If equipment damage is found or
suspected, file claims as soon as possible with
the transportation company and notify the
nearest representative of Powell.
Some equipment, devices, or components
may be shipped separately. Examples of items
that may be shipped separately are resistors or
power factor capacitors. These components
are identified by a number coinciding with the
number on the section on which they are to be
mounted.

Shipping and storage of electrical equipment
requires measures to prevent the deterioration
of the apparatus over a long unused period.
The mechanical and dielectric integrity must
be protected. Electrical equipment is designed
for use in a variety of environments. When
the equipment is in transit and storage, these
design considerations are not fully functional.
In general, the following measures must be
considered.
1. Equipment designed for indoor installation
must be stored indoors in a climate
controlled environment to prevent
condensation of moisture. Exposure to rain
and the elements, even for a short period,
can permanently damage the equipment.
Space heaters within the equipment should
be energized, if so equipped. Humidity
controlling desiccant materials should
be utilized when space heaters are not
provided or cannot be energized. The
temperature should be kept above 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
operational integrity.
