Table 3-1. Recommended Sizes for Input

Conductors and Line Fuses

*Sized per National Code for 80 °C rated copper conductors @ 30 °C ambient. Not

more than three conductors in raceway or cable. Local codes should be followed if they

specify sizes other than those listed above.

3.0. INSTALLATION

A. LOCATION

A proper installation site is necessary for the power source to provide depend-

able service. A proper installation site permits freedom of air movement through

the unit while minimizing exposure to dust, dirt, moisture, and corrosive vapors.

A minimum of 18 inches (46 cm) is required between the side and rear panels

of the power source and the nearest obstruction.

The selected site should also allow easy removal of the power source outer

enclosure for maintenance. See Table 2-1 for overall dimensions of the unit.

B. RECEIVING, UNPACKING AND PLACEMENT

When requesting information concerning this equipment, it is essential that

Item number, Serial number and Model number of the equipment be supplied.

1. Upon receipt, remove all packing material and carefully inspect for any

damage that may have occurred during shipment. Any claims for loss

or damage that may have occurred in transit must be filed by the

purchaser with the carrier. A copy of the bill of lading and freight bill will

be furnished by the carrier on request.

2. Remove the power source from the container. Remove all packing

materials. Check the container for any loose parts.

3. Check air passages at front and rear of cabinet, making sure that

packing material has not obstructed air flow through the power source.

4. Install the lifting bolt furnished with the power sources into the top of the

unit.

5. After selecting an installation site, place the power source in the desired

location. The unit may be lifted either by using the lifting bolt or by forklift

truck. If a forklift is used for lifting the unit, be sure that the lift forks are

long enough to extend completely under the base.

C. PRIMARY (INPUT) ELECTRICAL CONNECTION

This power source is a three-phase unit and must be connected to a three-

phase power supply. It is recommended that the unit be operated on a dedicated

circuit to prevent impairment of performance due to an overloaded circuit.

For lifting purposes and for keeping

dust, moisture, and other foreign ma-

terial from entering the power source,

the lifting eyebolt must be fully tight-

ened with a tool.

Do not use filters on this unit as they

would restrict the volume of intake air

required for proper cooling. Output

ratings on this unit are based on an

unobstructed supply of cooling air

drawn over its internal components.

Warranty is void if any type of filtering

device is used.
