SPRING-GOVERNOR 3830484 - 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
Unpack the equipment with care in order to avoid scratching painted surfaces.
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.
Move the unit to the mounting location. The unit can be moved by either of the following methods:
Attach an overhead crane to the eyebolts that are installed on the generator frame.
Use a lift truck in order to lift the generator. Refer to the Operation and Maintenance Manual, "Product Lifting" section.The hoist and the hoist cables should have a rating that is greater than the weight of the generator. When the unit is moved, ensure that the generator is completely supported by the lift truck's fork tines. Also ensure that the generator is balanced on the lift truck's fork tines. Slide the fork tines beneath the attached skid in order to lift the generator, if equipped. 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. Coolant flow must reach these openings. If the generator is exposed to harsh environmental conditions, the generator can be modified in the field in order to add filters and space heaters. In addition, a more rigid periodic maintenance schedule should be established.Electrical Measurements
Measure the insulation resistance of each winding if the generator was exposed to the following conditions:
Rapid changes in temperature
Freezing
Wet climate during shipment
Wet climate during storageNote: These tests should be conducted prior to any power connections that are being made. These tests should be conducted prior to any control connections that are being made.Refer to the Generator Maintenance section of this manual in order to measure the following items:
Exciter field (stator)
Exciter armature (rotor)
Generator field (rotor)
Generator armature (stator)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.
