PANEL AS 7V5929 - Caterpillar

Ensure that the electrical connections are properly located. Also ensure that the phase rotation is maintained. See illustration 2.Access can be obtained from either the top or from the bottom. Use care when you pull the cable from the top in order to avoid damage to the system components. Large cables require the optional cabinet for the termination of the wires. This makes the connections easier.Interface Connections
To install the customer interfaces, refer to Operation and Maintenance Manual, SEBU7311, "Interfaces".National Electric Code
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.
Table 1
System Specifications    
Nominal Input Current     307 A    
Rating for the Input Current (1)     385 A    
Nominal Operating Voltage     480 ACV    
Nominal Output Current     300 A    
Maximum Ambient Temperature    
40 °C (104 °F)    
Maximum Size of Conduit     4 inches    
( 1 ) The rating takes into account the noncontinuous charging current (5 minute maximum).The system is designed for the cable to enter the top or the bottom. The removable access plates should be punched in order to accommodate the size of the conduit. The cables for input and cables for output must be run in separate conduits. The connection terminals will accept a cable from number 2 AWG up to 600 MCM (2 per phase). The terminals can be oriented for top entry or for bottom entry. This is done in order to minimize the requirements for bends. The use of 600 MCM is not recommended. Space limitations require the use of smaller parallel cables. This will reduce the risk of damage to the unit while the cable is pulled. If the size of the cable is greater than 350 MCM and the top entry method is used, the optional termination cabinet should be used. This will make the wires easier to connect.Refer to "National Electric Code Article 210-19" and "National Electric Code Table 310-16" for the correct cable size.Refer to "National Electric Code Article 250-95" for the correct ground size.Refer to "National Electric Code Article 310-15" for the correct neutral size.The torque for the wire connections is 57 N m (42 lb ft).Note: A service disconnect device must be installed. This device must be properly rated for the output power.Mechanical
The system must be anchored to a foundation. The foundation should be a concrete slab that is fully cured. The slab should be poured with a minimum of 2000 psi concrete. The floor must be capable of supporting a load of 325 pounds per square foot. Refer to Operation and Maintenance Manual, SEBU7311, "Anchoring" for more information.Existing slabs should be free from cracks and seams in the vicinity of the installation. Refer to Operation and Maintenance Manual, SEBU7311, "Anchoring" in order to determine the requirements for the positioning of the slab.Bearing Retainers
Before the system is placed in operation, the shipping retainers must be removed and
