SECTION 2

INSTALLATION

2.1 LOCATION

A proper installation site is necessary for the power source to provide dependable service. A proper instal- lation 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. Also, the underside of the power source must be kept completely free of obstructions.

The selected site should also allow easy removal of the power source outer enclosure for maintenance. See Table 1.1 for overall dimensions of the unit.

2.2RECEIVING, UNPACKING AND PLACEMENT

A.Immediately upon receipt of the power source, inspect for damage which may have occurred in transit. Notify the carrier of any defects or dam- age.

B.Remove the power source from the container. Remove all packing materials. Check the con- tainer for any loose parts.

C.Check air passages at front and rear of cabinet, making sure that no packing materials that may obstruct air flow through the power source.

D.Install the lifting eyebolt furnished with the power source into the top of the unit.

For lifting purposes and for keeping dust, mois- ture, and other foreign material from entering the power source, the lifting eyebolt must be fully tightened with a tool.

E.After selecting an installation site (see para- graph 2.1), place the power source in the desired location. The unit may be lifted either by using the lifting eyebolt 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.

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 unob- structed supply of cooling air drawn over its inter- nal components. Warranty is void if any type of filtering device is used.

2.3PRIMARY (INPUT) ELECTRICAL CONNEC- TION

This power source is a three-phase unit and must be connected to a three-phase power supply. It is recom- mended that the unit be operated on a dedicated circuit to prevent impairment of performance due to an over- loaded circuit.

ELECTRIC SHOCK CAN KILL! Before making elec- trical input connections to the power source, "Ma- chinery Lockout Procedures" should be employed. If the connections are to be made from a line disconnect switch, place the switch in the off posi- tion and padlock it to prevent inadvertent tripping. If the connection is made from a fusebox, remove the corresponding fuses and padlock the box cover. If it is not possible to use padlocks, attach a red tag to the line disconnect switch (or fuse box) warning others that the circuit is being worked on.

A.The primary power leads must be insulated copper conductors. Three power leads and one ground wire are required. Either rubber covered cable or conduit (flexible or solid) may be used. Table 2-1 provides recommended input conduc- tors and line fuse sizes.

B.Remove the top cover. Identify primary power input connections on the power switch, chassis ground lug on the "A" frame, and primary input terminal board. Refer to Figures 2-1 and 2-2.

C.When using the provided strain relief, refer to Figure 2.1 for proper cable strip lengths. It is important to follow the cable strip guide to en- sure that if the primary input cable is ever pulled from the strain relief, the input conductors will be pulled from the ON/OFF power switch before the ground lead is pulled from the ground lug. Once stripped, thread the input and ground conduc- tors through the large strain relief in the rear panel of the power source. Connect the ground wire to the terminal lug located on the right rear A-frame leg inside the power source. Connect the primary power leads to terminals L1, L2, and L3 on the input power switch. Secure the strain relief on the input cable.

The chassis must be connected to an approved electrical ground. Failure to do so may result in electrical shock, severe burns or death.
