Heavy equipment.
Can cause death or serious
personal injury.
Exercise extreme care when
handling the motor control cen-
ter. Handle upright only. Do not
tilt. A crane or hoist should be
used if at all possible. Exercise
all safety precautions outlined
in the following discussion.
2.3 Skid Removal
Skid removal should be performed just prior to final placement
of the motor control center and is achieved by first removing
the
bottom horizontal wireway covers which allows access to the
skid lag bolts. Attach crane rigging to lifting angle on top of
MCC structure. Apply sufficient tension on the rigging to
remove all slack without lifting the equipment. This is a recom-
mended safety measure to reduce the possibility of tipping.
The lag bolts may now be removed, the MCC lifted, the skids
removed, the MCC lowered into place, and the anchor bolts
secured. The last operation should be performed with ade-
quate rigging tension to prevent tipping. After all additional
shipping sections are secured in a similar manner, sections and
bus bars should be joined in accordance with the instructions
in the Installation section of this manual. Close doors and rein-
stall covers as soon as possible to eliminate intrusion of dirt
and foreign materials into the MCC enclosure.

2.4 Storage
A motor control center or separate unit, which is not installed
and energized immediately, should be stored in a clean dry
space where a uniform temperature prevents condensation.
Preferably, it should be stored in a heated building, with ade-
quate air circulation and protected from dirt and water. Motor
control centers and units should be stored where they are not
subject to mechanical damage.
If the motor control center is to be stored for any length of
time, prior to installation, restore the packing for protection
during that period. Where conditions permit, leave the pack-
ing intact until the motor control center or sections are at
their final installation position. If the packing is removed,
cover the top and openings of the equipment during the con-
struction period to protect them against dust and debris.
If the equipment is to be stored in a cool or damp area, do not
completely cover the equipment, but provide heat to prevent
condensation of moisture in the equipment. If the control
center has been ordered with space heaters, connect to a tem-
porary feed for heat. A simple method of heating the motor
control center when space heaters are not ordered is to place
a standard 120V/15W lamp inside the bottom of each vertical
section.
An unenergized outdoor motor control center should be kept
dry internally by installing temporary heating (see previous
paragraphs), or by energizing optional self-contained space
heaters.
Any scratches or gouges suffered from shipping or handling
should be touched up to prevent rusting.
