Do not perform any procedure that is outlined in this Special Instruction until the entire instruction has been read and understood.This Special Instruction describes the proper grounding procedure for the 161-0797 Governor Control As .Grounding Practices
Failure to connect the unit to a suitable grounding electrode can result in electrical shock and may cause injury or death.
Proper grounding is necessary for optimum engine performance and reliability. Improper grounding will result in electrical current paths that are uncontrolled and unreliable.Uncontrolled electrical circuit paths can result in damage to main bearings, to crankshaft bearing journal surfaces, and to aluminum components. Uncontrolled electrical circuit paths can also cause electrical activity that may degrade the engine electronics and communications.Ensure that all grounds are secure and free of corrosion.Grounding Procedure
Illustration 1 g00015449
Ground symbolThe ground screw for the chassis is identified with the ground symbol. Refer to Illustration 1. This point must always be connected to the system ground at a central point. The housing for the Load Sharing Module (LSM) is painted. This painted housing will not provide a good ground connection. Use the designated ground screw for this purpose.Resistance from the ground screw of the module's chassis to the engine ground must be minimal. A resistance that is not greater than 0.1 ohms is optimal. Test the resistance in order to ensure compliance. The engine ground refers to the engine ground that is associated with this LSM. A greater resistance increases the risk of a potential hazard and of equipment damage.Avoid ground loops. Do not paint ground points.The following publications may provide additional information:
IEEE Standard 142" Recommended Practice for Grounding of Industrial and Commercial Power Systems"
IEEE Standard 1100" Recommended Practice for Powering and Grounding Sensitive Electronic Equipment"Electrical codes and service publications may provide additional requirements.Shielded Wiring
The following considerations are the primary purposes for grounding equipment:
Safety of personnel
Improved equipment operation
Continuity of serviceThere are four main reasons for having grounded systems:
Safety
Protection against a lightning strike
Reduction in the
