Moving MCC equipment
Move the equipment to the installation site using a
forklift or pallet jack, or via rod/pipe rolling. MCC
vertical sections are usually top- and front-heavy
when units are installed, but top- and back-heavy
when empty (withdrawable units removed). Be sure
to balance your loads carefully when moving them,
and use safety straps when handling with a forklift.
For added stability and safety, leave the sections
attached to their shipping skids during
transportation to the installation site.
At the installation site, you may tilt empty vertical
sections back to the horizontal position if
necessary to fit through doors or other low
openings. When transporting sections horizontally,
they must be supported over a wide area to avoid
distortion or damage.
Temporary storage
If the MCC won’t be installed directly after arrival, it
should be stored under the following conditions in
order to avoid damage:
• Unpack the components immediately upon
delivery so that they can be inspected for
damage.
• See 2.2. Receiving section of this manual.

permissible rope loading
• Open section doors for several hours to
acclimatize the equipment.
• Store the components indoors in a condensation-
free environment.
• The storage building should have a well-drained
paved floor. The temperature should be between
23°F (-5°C) and 104°F (40°C). The air should be dry
(50% maximum humidity).”
• Before energizing the space heaters remove all
packing materials from the MCC.
• Using a separate power supply turn on the space
heaters by the thermostat adjusting them
between 35°C (95°F) and 40°C (104°F) during the
storage to prevent condensation.
• Do not omit the use of appropriate personal
protective equipment (PPE) necessary to do the
connections of the power supply of the heaters.
• Cover the sections with plastic sheeting to
protect them from dripping water.
• During the operation of the heaters, these must
be monitored to avoid any damage that may
cause a fire.
• Check once per week for condensation on the
components. If condensation is detected, dry the
equipment and move it to a different storage
area.
• The storage building should have a well-drained,
paved floor. The temperature should be between
23°F (-5°C) and 104°F (40°C). The air should be dry
(50% maximum humidity).”
TIP: If the MCC does not have space heaters
installed, you may be able to hang a 100 watt
incandescent light bulb inside the MCC enclosure
to act as a space heater and reduce condensation.
If your delivery includes spare units, store them
following these instructions:
• Store in an area with temperatures above -10°C
(14°F) but not exceeding 40°C (104°F) at 85%
non-condensing humidity.
• Store the boxes top-side up.
• Do not stack units larger than 450 mm (18 in) on
top of each other.
