ROLLER ASSEM. 2H6490 - Caterpillar

Receiving Inspection
If the generator is received during cold weather, allow the unit to reach room temperature before you remove the protective packing material. Warming the generator to room temperature will prevent the following problems:
Water condensation on cold surfaces
Early failures due to wet windings
Early failures due to wet insulating materialsUnpacking
Moving the Generator
Improper lift rigging can allow unit to tumble causing injury and damage.
Do not use the engine lifting eyes to remove the engine and generator together.
Unpack the equipment with care to avoid scratching painted surfaces. Move the unit to the mounting location. Follow the instructions under the "Product Lifting" topic. The hoist and the hoist cables should have a rating that is greater than the weight of the generator.Location
The location of the generator must comply with all local regulations. The location of the generator must also comply with all special industrial regulations. Locate the generator in an area that meets the following requirements:
Clean
Dry
Well-ventilated
Easily accessible for inspection and maintenanceDo not obstruct air inlet openings. Do not obstruct discharge openings. Air flow must reach these openings. If the generator is exposed to harsh environmental conditions, the generator can be modified in the field to add filters and space heaters. In addition, a more rigid periodic maintenance schedule should be established.Note: For further information concerning the installation of this generator set, see the appropriate Application and Installation Guide.Protective Devices
The output to the load of the generator should always be protected with an overload protection device such as a circuit breaker or fuses. Fuses should be sized by using the lowest possible current rating. However, this rating must be above the current rating for full load. A common recommendation is 115 percent of rated current. Determine the size of fuses or determine the size of circuit breakers in accordance with NEMA, IEC, and Local Electrical Codes.Storage
If the generator is not installed immediately, refer to the "Product Storage" topic for the proper considerations for storing the unit.Load Connections – Generator Set Output
For units equipped with a circuit breaker: Installer shall connect and size conductors based on ampacities found in the 75° C (167° F) column within Table 310.15(B) of the "National Electrical Code®, ANSI/NFPA 70". An ampacity of no less than 115 percent (115%) of the maximum rated circuit current during normal operating conditions shall be used. All conductor insulation shall be rated 90° C (194° F) or greater.Installation Access:
This stationary engine generator assembly shall be installed so that access is restricted to only qualified service personnel who have been instructed of the reasons for the restrictions applied to the location, and about any precautions that must be taken. Access shall be by using a special tool, or lock and key, or other means of security and shall be controlled by the authority responsible for the location.Batteries and Servicing:
This stationary engine generator assembly utilizes multiple batteries to produce a nominal 24V DC power supply.Battery servicing is to be performed or supervised by qualified personnel knowledgeable of batteries and the required precautions. Keep unauthorized and
