SECTION 2

2.1 GENERAL

Proper installation can contribute materially to the satisfactory and trouble-free
operation of the power source. It is suggested that each step in this section
be studied carefully and followed as closely as possible.

2.1.1 Unpacking and Placement

1. Immediately upon receipt of the power source, it should be inspected
for damage which may have occurred in transit. Notify the carrier of
any defects or damage at once.
2. After removing the power source from the shipping container, check
the container for any loose parts. Remove all packing materials.
3. Check air passages at front, bottom, and rear of cabinet for any pack-
ing materials that may obstruct air flow through the power source.
4. If the machine is not to be installed immediately, store it in a clean,
dry, well-ventilated area.
5. The location of the power source should be carefully selected to ensure
satisfactory and dependable service. Using the lifting eyebolt, or a
fork-lift truck, place the power source in the desired location. Choose
a location relatively close to a properly fused supply of electrical
power.
6. The power source's components are maintained at proper operating
temperature by forced air which is drawn through the cabinet by the
fan unit on the rear panel. The power source is designed to operate
up to a 40 °C (104 °F) ambient temperature. For this reason, locate
the machine in an open area where air can circulate freely at front,
bottom, and rear openings. Leave at least 2 feet of clearance between
the rear of the power source and wall or other obstruction.
IMPORTANT: Do not use filters on this unit. Output ratings are designed
and based on an unobstructed supply of "clean" cooling
air drawn over its internal components. If cooling air is
dirty (e.g., laden with conductive dust), the interior should
be cleaned using low pressure air (see Maintenance).
