CAP ASSEMBLY 0379497 - Caterpillar

Guidelines for Selection of a Site and the Preparation of a Site
Place the system in a reasonably clean environment that is free of dust. The air must be free to circulate around the unit. Cooling air enters the unit on the bottom section of the front of the enclosure. The cooling air exhausts through the top of the enclosure.
Avoid placing the unit in direct sunlight or near other heat sources.
Verify that the floor is a minimum of 2000 psi concrete that is capable of supporting 325 pounds per square foot.
Verify that the ambient temperature is within -20 °C to 40 °C (-4 °F to 104 °F). Refer to Specifications.
A clearance of 914 mm (36 inches) is required from the front of the unit for service. See the illustrations in Installation, "Anchoring". The sides of the system can be placed against walls. A minimum distance from the edge of the slab should be maintained. However, several feet of additional space is preferable for improved airflow and easier cable connections. There is a minimum clearance of 610 mm (24 inches) that is needed between the top of the system and the ceiling in order to have proper airflow. See the illustrations in Installation, "Anchoring". The cooling air exhausts at a rate of 2500 cfm. A clearance of 457 mm (18 inches) between the top of the system and the ceiling is acceptable if there is an adequate airflow on the sides of the unit.
The anchor bolts should be torqued to 41 N m (30 lb ft).
The system should not be operated in a sealed room or a sealed container. If the system must be operated in a sealed room adequate climate control must be provided. If HVAC is necessary, note that the heat that is generated from the system may exceed the specifications when the system is protecting loads with a low power factor or non-linear loads.
The floor must be 2 to 3 degrees of being level. The floor should be concrete or some other suitable substance that can meet the load requirements of the anchor bolts. Refer to Operation Section, "Anchoring".
A power outlet must be located within 9 m (30 ft) of the system. The outlet will be used in order to power the vacuum pump during maintenance and initial start-up.
An adequately sized neutral is required on the input and on the output of the system.
An optional cabinet for the termination of the wires adds approximately 425 mm (16.75 inch) to the width of the system. The following conditions will require a cabinet: The cables enter the top of the unit. and The cable size is greater than 2 by 350 MCM per phase.Electrical
The system should be installed per the National Electrical Code (NEC) and the local codes. The size of the cable and the conduit should be based on the following system specifications.
