  • Page 11: Engine Exhaust Gas

    2.4.5 ENGINE EXHAUST GAS Before starting the generator engine, you should be sure there is no way for exhaust gases to enter the vehicle interior and endanger people or animals. Close windows, doors and other openings in the vehi- cle that, if open, might permit exhaust gases to enter the vehicle.

  • Page 12: Do Not Overload The Generator

    Section 2 – Operation PRIMEPACT 66G and 66LP Recreational Vehicle Generators 2.7.2 DO NOT OVERLOAD THE GENERATOR You can read the rated wattage/amperage capacity of your generator on the generator data decal (see Section 1.1 on Page 4). Applying electrical loads in excess of the unit’s rated capacity will cause the engine/generator to automati- cally shut down.

  • Page 13: Overvoltage Protection

    2.8.4 OVERVOLTAGE PROTECTION A solid-state voltage regulator (Figure 2.5) controls the generator’s AC output voltage. This regulator sup- plies an excitation current to the rotor. By regulating the rotor’s excitation current, the strength of its mag- netic field is regulated and, in turn, the voltage deliv- ered to connected electrical loads is controlled.

    Section 3 – Maintenance PRIMEPACT 66G and 66LP Recreational Vehicle Generators CHANGING THE ENGINE OIL AND/OR OIL FILTER • Change the engine oil after the first 25 hours of operation (after the 25-hour break-in period, see Section 2.8.5, Page 10). Thereafter, change the oil every 100 operating hours.

    Section 3 – Maintenance PRIMEPACT 66G and 66LP Recreational Vehicle Generators Be sure to reinstall the muffler plug tightly. Engine vibration could cause a loose plug to fall out. Without the plug in place, hot engine exhaust is directed out the opening. This hot exhaust, depending on the installation, could be directed to areas not able to withstand the extreme heat such as wooden floor boards or...

    Section 6 – Installation PRIMEPACT 66G and 66LP Recreational Vehicle Generators • If constructing a compartment, line the exterior (underside) of the compartment floor with 26-gauge galvanized steel. • All seams, splices and joints of the compartment walls (unless vapor tight by design) should be caulked to prevent poisonous, flammable or explo- sive vapors from entering the vehicle interior.

  • Page 27: Compartment Floor Cutouts

    • Vapor seal all compartment seams and joints. • Over the galvanized steel lining, install a combination of acoustical materials as mentioned in Section 6.2.3. To prevent fire or explosion, do not install any insulation or other absorbent materials on the interior or underside of the compartment floor.

    Section 6 – Installation PRIMEPACT 66G and 66LP Recreational Vehicle Generators • From the junction box, route power supply wires through approved conduit to either (a) double-pole, double-throw transfer switch, or (b) approved isola- tion receptacle. Connecting to a transfer switch or isolation receptacle must prevent vehicle electrical circuits from being connected to two different power supplies at the same time (such as generator and...

  • Page 35: Battery Cables

    6.8.2 BATTERY CABLES Using battery cables that are too long or too small in diameter may cause a drop in voltage, which causes starting problems. For the best cold weather starting, the voltage drop between battery terminals and the gen- erator connection point should not exceed 0.12 volts per 100 amperes of cranking current.
