Storage
Place the equipment on the shipping base. Store all equipment indoors in a well-ventilated 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).
The sections ship wrapped in plastic for protection during shipment only. Remove the plastic wrap just before
placing into storage. Cover with heavy wrapping paper or other moisture barrier. Use materials that will not
trap moisture inside the unit. Do not cover louvered openings.
For long-term storage, or in high-humidity, use space heaters to keep the interior dry. Bring power for the
space heaters to the load terminals of the device that controls the heater circuits.
Note: The heater can be energized with an external source of power.
• Store contactors upright in their original shipping base
• Do not stack
• Do not store contactors in the compartments
Overview
Before installing, consult all drawings supplied for the particular order. Drawings show top and front views of
the lineup, primary and secondary connection diagrams and Bills of Materials. Study these drawings and the
following recommendations before preparing the site plan drawings.
Location
Locate the lineup in accordance with local regulations. Clearances at the front should allow installation and
removal of the draw-out equipment and lift devices. Allow enough clearance to service draw-out equipment in
back to back installations (when it is applicable).
Foundation
The factory supplies floor plan drawings for each installation. The floor must be straight and level within 0.25
inches over the full length and depth of the lineup. The finished floor under and in front of the line-up should
be smooth.
Install power and secondary (control) conduits before moving the unit to the site. Available space for the
conduits appears on the floor plans supplied with the units. Conduits should not extend more than one inch
above the station floor level. Cover the conduit openings in the floor.
Location site preparation
* Maintain approximately 4 feet or more clearance from the top of the equipment to any obstruction.
