SAFETY INFORMATION
ENGINE SAFETY
DANGER
NOTICE
NEVER run engine without an air filter or with a dirty air
filter.Severe engine damage may occur.Service air filter
frequently to prevent engine malfunction.
The engine fuel exhaust gases contain poisonous carbon
monoxide. This gas is colorless and odorless, and can
cause death if inhaled.
NEVER tamper with the factory settings
of the engine or engine governor. Damage
to the engine or equipment can result
if operating in speed ranges above the
maximum allowable.
The engine of this equipment
requires an adequate free
flow of cooling air. NEVER
operate this equipment in
any enclosed or narrow area
where free flow of the air is
restricted. If the air flow is
restricted it will cause injury to people and property and
serious damage to the equipment or engine.
Wet stacking is a common problem with diesel engines
which are operated for extended periods with light or
no load applied.When a diesel engine operates without
sufficient load (less than 40% of the rated output), it will
not operate at its optimum temperature. This will allow
unburned fuel to accumulate in the exhaust system,
which can foul the fuel injectors, engine valves and
exhaust system, including turbochargers, and reduce
the operating performance.
WARNING
DO NOT place hands or fingers inside engine
compartment when engine is running.
In order for a diesel engine to operate at peak efficiency,
it must be able to provide fuel and air in the proper ratio
and at a high enough engine temperature for the engine
to completely burn all of the fuel.
NEVER operate the engine with heat shields or
guards removed.
Keep fingers, hands hair and clothing away
from all moving parts to prevent injury.
Wet stacking does not usually cause any permanent
damage and can be alleviated if additional load is
applied to relieve the condition.It can reduce the system
performance and increase maintenance. Applying an
increasing load over a period of time until the excess
fuel is burned off and the system capacity is reached
usually can repair the condition. This can take several
hours to burn off the accumulated unburned fuel.
DO NOT remove the radiator cap while the
engine is hot. High pressure boiling water
will gush out of the radiator and severely
scald any persons in the general area of
the generator.
DO NOT remove the coolant drain plug while the engine
is hot. Hot coolant will gush out of the coolant tank and
severely scald any persons in the general area of the
generator.
State Health Safety Codes and Public Resources
Codes specify that in certain locations, spark arresters
must be used on internal combustion engines that use
hydrocarbon fuels.A spark arrester is a device designed
to prevent accidental discharge of sparks or flames
from the engine exhaust. Spark arresters are qualified
and rated by the United States Forest Service for this
purpose. In order to comply with local laws regarding
spark arresters, consult the engine distributor or the
local Health and Safety Administrator.
DO NOT remove the engine oil drain plug while the
engine is hot. Hot oil will gush out of the oil tank and
severely scald any persons in the general area of the
generator.
CAUTION
NEVER touch the hot exhaust manifold,
muffler or cylinder.Allow these parts to cool
before servicing equipment.

INSTALLATION
OUTDOOR INSTALLATION
GENERATOR GROUNDING
Install the generator in a area that is free of debris,
bystanders, and overhead obstructions. Make sure the
generator is on secure level ground so that it cannot slide
or shift around. Also install the generator in a manner so
that the exhaust will not be discharged in the direction of
nearby homes.
To guard against electrical shock and possible damage to
the equipment, it is important to provide a good EARTH
ground.
Article 250 (Grounding) of the National Electrical Code
(NEC) provides guide lines for proper grounding and
specifies that the cable ground shall be connected to the
grounding system of the building as close to the point of
cable entry as practical.
The installation site must be relatively free from moisture
and dust.All electrical equipment should be protected from
excessive moisture. Failure to do will result in deterioration
of the insulation and will result in short circuits and
grounding.
NEC articles 250-64(b) and 250-66 set the following
grounding requirements:
1. Use one of the following wire types to connect the
generator to earth ground.
Foreign materials such as dust, sand, lint and abrasive
materials have a tendency to cause excessive wear to
engine and alternator parts.
a. Copper - 8 AWG (5.3 mm2)
b. Aluminum - 6 AWG (8.4 mm2)
CAUTION
Pay close attention to ventilation when operating the
generator inside tunnels and caves.The engine exhaust
contains noxious elements. Engine exhaust must be
routed to a ventilated area.
2. When grounding the generator (Figure 2) connect the
ground cable between the lock washer and the nut on
the generator and tighten the nut fully. Connect the
other end of the ground cable to earth ground.
3. NEC article 250-52(c) specifies that the earth ground rod
should be buried a minimum of 8 ft. into the ground.
INDOOR INSTALLATION
Exhaust gases from diesel engines are extremely
poisonous. Whenever an engine is installed indoors the
exhaust fumes must be vented to the outside. The engine
should be installed at least two feet from any outside wall.
Using an exhaust pipe which is too long or too small can
cause excessive back pressure which will cause the engine
to heat excessively and possibly burn the valves.
NOTICE
When connecting the generator to any buildings
electrical system ALWAYS consult with a licensed
electrician.
MOUNTING
The generator must be mounted on a solid foundation (such
as concrete) and set firmly on the foundation to isolate
vibration of the generator when it is running.The generator
must set at least 6 inches above the floor or grade level (in
accordance to NFPA 110, Chapter 5-4.1).DO NOT remove
the metal skids on the bottom of the generator. They are
to resist damage to the bottom of the generator and to
maintain alignment.

GENERAL INFORMATION
GENERATOR
OPEN DELTA EXCITATION SYSTEM
The MQ Power Model DCA250SSI/DCA250SSIU are 220
kW generators (Figure 3) that are designed as a high quality
portable (requires a trailer for transport) power source for
telecom sites, lighting facilities, power tools, submersible
pumps and other industrial and construction machinery.
These generators are equipped with the state of the art
“Open-Delta” excitation system. The open delta system
consist of an electrically independent winding wound
among stationary windings of the AC output section.
There are four connections of the open delta A, B, C and
D. During steady state loads, the power from the voltage
regulator is supplied from the parallel connections of A to
B, A to D, and C to D. These three phases of the voltage
input to the voltage regulator are then rectified and are the
excitation current for the exciter section.
ENGINE OPERATING PANEL
The “Engine Operating Panel” is provided with the following:
Tachometer
Emergency Stop Switch
Water Temperature Gauge
Oil Pressure Gauge
Charging Ammeter Gauge
Fuel Level Gauge
Battery Switch
When a heavy load, such as a motor starting or a short
circuit occurs, the automatic voltage regulator (AVR)
switches the configuration of the open delta to the series
connection of B to C. This has the effect of adding the
voltages of each phase to provide higher excitation to the
exciter section and thus better voltage response during the
application of heavy loads.
Pre-Heat Lamp
Engine Alarm Lamps (DCA-250SSI 5 Alarm Lamps)
Engine Alarm Lamps (DCA-250SSIU 4 Alarm Lamps)
Engine Speed Switch
GENERATOR CONTROL PANEL
The “Generator Control Panel” is provided with the following:
Frequency Meter (Hz)
The connections of the AVR to the AC output windings are
for sensing only. No power is required from these windings.
The open-delta design provides virtually unlimited excitation
current, offering maximum motor starting capabilities.The
excitation does not have a “fixed ceiling” and responds
according the demands of the required load.

LOAD APPLICATION
SINGLE PHASE LOAD
THREE PHASE LOAD
Always be sure to check the nameplate on the generator
and equipment to insure the wattage, amperage, frequency,
and voltage requirements are satisfactorily supplied by the
generator for operating the equipment.
When calculating the power requirements for 3-phase
power use the following equation:
Generally, the wattage listed on the nameplate of the
equipment is its rated output. Equipment may require
130—150% more wattage than the rating on the nameplate,
as the wattage is influenced by the efficiency, power factor
and starting system of the equipment.
NOTICE
If 3Ø load (kVA) is not given on the equipment
nameplate, approximate 3Ø load may be determined
by multiplying voltage by amperage by 1.732.
NOTICE
If wattage is not given on the equipment’s name plate,
approximate wattage may be determined by multiplying
nameplate voltage by the nameplate amperage.
NOTICE
Motors and motor-driven equipment draw much greater
current for starting than during operation.
WATTS = VOLTAGE x AMPERAGE
An inadequate size connecting cable which cannot carry the
required load can cause a voltage drop which can burn out
the appliance or tool and overheat the cable. SeeTable 6.
The power factor of this generator is 0.8.SeeTable 5 below
when connecting loads.
When connecting a resistance load such as an
incandescent lamp or electric heater, a capacity of up to
the generating set’s rated output (kW) can be used.

A slack fan belt may contribute to overheating, or to
insufficient charging of the battery. Inspect the fan belt for
damage and wear and adjust it in accordance with the
ISUZU Engine Owner’s Manual.
Day-to-day addition of coolant is done from the recovery
tank.When adding coolant to the radiator, DO NOT remove
the radiator cap until the unit has completely cooled. See
Table 10 for engine, radiator, and recovery tank coolant
capacities.Make sure the coolant level in the recovery tank
is always between the “H” and the “L” markings.

1. NEVER connect the battery cables to the battery
terminals when the MPEC Control Switch is in either
the MANUAL position. ALWAYS make sure that the
MPEC Control Switch is in the OFF/RESET position
when connecting the battery.
This unit is of negative ground DO NOT connect in reverse.
Always maintain battery fluid level between the specified
marks. Battery life will be shortened, if the fluid level are
not properly maintained. Add only distilled water when
replenishment is necessary.
2. Place a small amount of battery terminal treatment
compound around both battery terminals. This will
ensure a good connection and will help prevent
corrosion around the battery terminals.
DO NOT over fill. Check to see whether the battery
cables are loose. Poor contact may result in poor starting
or malfunctions. Always keep the terminals firmly
tightened. Coating the terminals with an approved battery
terminal treatment compound. Replace battery with only
recommended type battery. The battery type used in this
generator is BCI Group 27.
NOTICE
If the battery cable is connected incorrectly, electrical
damage to the generator will occur.Pay close attention to
the polarity of the battery when connecting the battery.
The battery is sufficiently charged if the specific gravity
of the battery fluid is 1.28 (at 68° F). If the specific gravity
should fall to 1.245 or lower, it indicates that the battery is
dead and needs to be recharged or replaced.
CAUTION
Inadequate battery connections may cause poor
starting of the generator, and create other malfunctions.
Before charging the battery with an external electric source,
be sure to disconnect the battery cables.
Battery Cable Installation
ALTERNATOR
ALWAYS be sure the battery cables (Figure 34) are properly
connected to the battery terminals as shown below. The
red cable is connected to the positive terminal of the

MAINTENANCE
If the engine is operating in very dusty or dry grass
conditions, a clogged air cleaner will result.This can lead to
a loss of power, excessive carbon buildup in the combustion
chamber and high fuel consumption. Change air cleaner
more frequently if these conditions exists.
FUEL TANK INSPECTION
In addition to cleaning the fuel tank, the following
components should be inspected for wear:
Rubber Suspension — look for signs of wear or
deformity due to contact with oil. Replace the rubber
suspension if necessary.
FUEL ADDITION
Add diesel fuel (the grade may vary according to season
and locations).
Fuel Hoses — inspect nylon and rubber hoses for signs
of wear, deterioration and hardening.
Removing Water from the Fuel Tank
FuelTank Lining — inspect the fuel tank lining for signs
of excessive amounts of oil or other foreign matter.
After prolonged use, water and other impurities accumulate
in the bottom of the tank. Occasionally inspect the fuel
tank for water contamination and drain the contents if
required.
Replacing Fuel Filter
Replace the fuel filter cartridge with new one every 500
hours or so.
During cold weather, the more empty volume inside the
tank, the easier it is for water to condense. This can be
reduced by keeping the tank full with diesel fuel.
Loosen the drain plug at the lower top of the fuel filter.
Drain the fuel in the fuel body together with the mixed
water. DO NOT spill the fuel during disassembly.
Cleaning Inside the Fuel Tank
Vent any air
Drain the fuel inside the fuel tank completely.Using a spray
washer (Figure 59) wash out any deposits or debris that
have accumulated inside the fuel tank.
AIR REMOVAL
If air enters the fuel injection system of a diesel engine,
starting becomes impossible. After running out of fuel,
or after disassembling the fuel system, bleed the system
according to the following procedure. See the ISUZU
Engine Manual for details.

MAINTENANCE
To restart after running out of fuel, turn the switch to the
“ON” position for 15-30 seconds.Try again, if needed.This
unit is equipped with an automatic air bleeding system.
RADIATOR CLEANING
The radiator (Figure 60) should be sprayed (cleaned) with
a high pressure washer when excessive amounts of dirt
and debris have accumulated on the cooling fins or tube.
When using a high pressure washer, stand at least 5 feet
(1.5 meters) away from the radiator to prevent damage to
the fins and tube.
CHECK OIL LEVEL
Check the crankcase oil level prior to each use, or when the
fuel tank is filled.Insufficient oil may cause severe damage
to the engine. Make sure the generator is level. The oil
level must be between the two notches on the dipstick as
shown in Figure 27.
Replacing Oil Filter
Remove the old oil filter.
Apply a film of oil to the gasket on the new oil filter.
Install the new oil filter.
After the oil cartridge has been replaced, the engine oil
will drop slightly.Run the engine for a while and check for
leaks before adding more oil if needed. Clean excessive
oil from engine.

MAINTENANCE
The purpose of these receptacles is to provide power via
commercial power to the jacket water heater and internal
battery charger.
If the generator will be used daily, the battery should
normally not require charging. If the generator will be idle
(not used) for long periods of time, apply power to the
battery charger receptacle via commercial power using a
power cord of adequate size.
These receptacles will ONLY function when commercial
power has been supplied to them (Figure 61). To apply
commercial power to these receptacles, a power cord of
adequate size will be required (Reference Table 6).
NOTICE
To ensure adequate starting capability, always have
power applied to the generator's internal battery
charger.
When using the generator in hot climates there is no reason
to apply power to jacket water heater. However, if the

TRAILER MAINTENANCE
BRAKES
Hydraulic Surge Brakes
Trailer brakes should be inspected the first 200 miles of
operation.This will allow the brake shoes and drums to seat
properly.After the first 200 mile interval, inspect the brakes
every 3,000 miles. If driving over rough terrain, inspect the
brakes more frequently.
Hydraulic surge brakes (Figure 62) should not require any
special attention with the exception of routine maintenance
such as shoe and lining replacement. Brake lines should
be periodically checked for cracks, kinks, or blockage.
Figure 60 displays the major hydraulic surge brake
components that will require inspection and maintenance.
Please inspect these components as required using steps
1 through 8 and Table 13 as listed below:
Brake Adjustment
1. Place the trailer on jack stands. Make sure the jack
stands are placed on secure level ground.
2. Check the wheel and drum for free rotation.
3. Remove the adjusting hole cover from the adjusting
slot at the bottom brake backing plate.
Figure 62. Hydraulic Brake Components
4. With a screwdriver or standard adjusting tool, rotate
the star wheel of the adjuster assembly to expand the
brake shoes.
Actuator
Hydraulic surge braking requires the installation of an
actuator at the tongue of the trailer. Remember the surge
or push of the trailer toward the tow vehicle automatically
synchronizes the trailer brakes with the tow vehicle brakes.
As the trailer pushes against the tow vehicle the actuator
telescopes together and applies force to the master cylinder,
supplying hydraulic pressure to the trailer brakes.
5. Adjust the brake shoes outward until the pressure of
the lining against the wheel drum makes the wheel
difficult to turn.
6. Adjust, rotate the star wheel in the opposite direction
until the wheel rotates freely with slight lining drag.
7. Replace the adjusting hole cover and lower the trailer
to the ground.
Periodicallycheckandtestthesurge“actuator”tomakesurethat
it is functioning correctly. Never use an undersize actuator.
