If the motor control center cannot be placed into
service reasonably soon after its receipt, it should
be stored in a clean, dry and ventilated building
free from temperature extremes. Acceptable
storage temperature are from 0°C (32°F) to 40°C
If the storage area is cool and/or damp, enough
heat should be provided to prevent condensation
which may be harmful to the motor control center.
Contact your local Square D field office.
NOTE: Outdoor storage is inadequate, even with
the protection of a tarpaulin.
Adequate equipment for handling the motor control
centers such as fork truck, crane, or rods and pipe
rollers must be available. The table below gives
the approximate weight of a single section for
determining what type of equipment to use for
handling. A single skid could contain from one to
three vertical sections.
Weight per Section
15 381 mm D Front of Board
20 581 mm D Front of Board
20 581 mm D Back to Back
The following instructions are provided to avoid
injury and equipment damage while moving the
motor control centers.
Verify the capabilities of the moving equipment
to handle the weight.
Fork trucks, when available, provide a quick
and convenient method of moving motor
Lifting angles are provided on each shipping
block for handling the motor control center by
overhead cranes. The following precautions
should be taken when using a crane
a. Handle in the upright position only.
b. Select rigging lengths to compensate for
any unequal weight distribution.
c. Do not exceed the 45° maximum between
the vertical and lifting cables.
d. Use only slings with safety hooks or
shackles. Do not pass ropes or cables
through the holes in the lifting angle.
5. USE EXTREME CAUTION WHEN MOVING
SECTIONS WITH RODS OR PIPE ROLLERS.
THERE IS A TENDENCY FOR THE CONTROL
CENTER TO TILT DUE TO ITS HIGH CENTER
After the shipping section is in place, its lifting
angle may be removed and discarded. To prevent
entrance of foreign matter, replace all hardware
which was used to secure the lifting angle.
