A certain amount of vibration is inherent in theoperation of any generator set. If vibration istransmitted to surrounding areas, the noise levelincreases. The engine generator is mounted directly tothe skid; therefore, twelve vibration isolators arerecommended to be installed between the skid andfoundation. Figure 17-4 illustrates the recommendedtype of isolator.17-25. When the generator set is installed within abuilding, all fuel, coolant, exhaust, and electricalconnections must have flexible sections so that vibrationis not transmitted along these lines. See Figure 17-5.Section V. AIR REQUIREMENTS FOR UNHOUSED 500 KW GENERATOR SETS INSTALLED WITHIN A BUILDING17-26. A ventilation system must be installed to provideadequate air at the generator set to remove heatradiated by the engine generator and supply combustionair for the engine.17-27. When installing the ventilation system thefollowing factors should be considered:a.Location of inlet and outlet air ports.b.Method of actuation of inlet and outlet louvers.c.Ambient temperature.d.Routing of exhaust air duct.e.Placement of discharge louver.f.Whether radiator and fan assembly will beseparated from the generator set.17-28. The air inlet and outlet must be in the sameroom position to allow convection air flow from the inlet,across the unit, and exhausted through17-7
