1/2"	Dry 85 Ft-Lbs	Lubed	65 Ft-Lbs

GENERATOR AND LOAD

COMPATIBILITY

The generator must be fully compatible with the rated voltage, phase and frequency of the connected electrical loads. The gen- erator, connected electrical devices, or both, can be damaged if voltage, phase and frequency are not compatible.

NOTE:

This manual assumes that the stationary emergency generator has been properly selected, installed and interconnected by a competent, qualified electrician or installation contractor. Once the installation is complete, do nothing that may result in non- compatibility between the generator and connected electrical loads.

STARTING AIDS

The stationary emergency generator may be equipped with one or more starting aids that serve to provide quicker, easier starts under varying climactic conditions.

This generator may have been mounted with (a) an engine coolant heater, (b) an engine oil heater, (c) a battery warmer or (d) a bat- tery charger. These aids are powered by a normal (utility) power source during nonoperating periods.

General Information

ENGINE COOLANT HEATERS

If the unit is equipped with an engine coolant (block) heater (Figure 1.11), it is powered by a circuit normally fed by the utility power supply. This heats the engine coolant when the unit is not operat- ing. This action keeps the engine warm even in cold weather, helping to ensure quicker starts. Heated coolant in the engine rises continuously drawing cold coolant into the heater, creating a constant flow of warm coolant through the engine.

ENGINE OIL HEATER (OPTIONALl

The engine oil heater is designed for installations where the engine oil must be kept near operating temperature at all times. If included with this unit, alow-watt density heater and thermostat are mount- ed in the engine'soil sump or on the sump pan (Figure 1.12). The heater and thermostat do not require maintenance.

1.Disconnect battery cables to prevent accidental start-up. Disconnect the negative battery cable first from the battery post indicated by (-) or NEG.

2.Make sure power is off from the appropriate power source.

3.To connect the wires, hold the bare metal leads together and place awire nut over them, then twist clockwise until tight. For all these connections, use the wire nuts provided.

4.Connect the ground wire from 120V power source to the ground wire from oil heater.

5.Using wire nuts provided connect the white wire and black wire from the oil heater as follows:

•The white (common) power wire from 120V power source to 1st wire from the oil heater.

•The wire from load side of thermostat to 2nd wire from the oil heater.
