General Information
FIELD WIRING CONNECTIONS TO BUSS BARS
ENGINE COOLANT HEATERS
500Kw Volvo and 500/600Kw Doosan powered units supplied
with Series C - R Frame Breakers rated 1400, 1600, 2000 and
2500A have Buss Bars supplied in the connection Module for the
connection of the Field Conductors. The following information
should be followed in order to obtain a suitable electrical connec-
tion to the Buss Bars.
• Conductor Lugs - The Buss Bars have been configured to
accept Aluminum Compression Lugs suitable for copper or
aluminum stranded wire .
• Suggested Manufacturer - PENN UNION CORP
• Manufacturers Part No. - BLUA060D2
• Type - Dual Rated (Al/CU), Two
Studs spaced 1 3/4" Apart
• Wire Size - 600 kcmil
Required Hardware
Below is the recommended hardware required to attach the Lugs
to the Buss Bars,
• M12 x 65mm Grade 8,8 Hex Head Cap Screw, M12 Flat
Washers, Lock Washer and Nut
or
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.

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.
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.
TYPES
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's oil 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.
