DCA-300SSK SERIES — INSTALLATION
Generator Grounding
Outdoor Installation
To guard against electrical shock and possible damage to
the equipment, it is important to provide a good EARTH
ground.
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.
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:
Foreign materials such as dust, sand, lint and abrasive
materials have a tendency to cause excessive wear to
engine and alternator parts.
1. Use one of the following wire types to connect the
generator to earth ground.
a. Copper - 10 AWG (5.3 mm2) or larger.
b. Aluminum - 8 AWG (8.4 mm2) or larger.
CAUTION - EXHAUST HAZARD
2. When grounding the generator (Figure 3) 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.
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.
3. NEC article 250-52(c) specifies that the earth ground
rod should be buried aminimum 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.
When connecting the generator to
any buildings electrical system
ALWAYS consult with a licensed
NOTE
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.

DCA-300SSK SERIES — GENERAL INFORMATION
Open Delta Excitation System
DCA-300SSK FAMILIARIZATION
Generator
The DCA-300SSK series 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.
The MQ Power DCA-300SSK series generators are 240 kW
generators 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.
There are four leads: A, B, C and D. During light loads, the
power to the AutomaticVoltage Regulator (AVR) is supplied
from the leads parallel connections of B&C. When loads
increase, the AVR switches and accepts power from leads
A&D. The output of leads A&D increase proportionally with
load. This of adding the voltages to each phase provides
better voltage response during heavy loads.

DCA-300SSK SERIES — LOAD APPLICATION
Single Phase Load
Three Phase Load
When calculating the power requirements for 3-phase power
use the following equation:
Always be sure to check the nameplate on the generator
and equipment to insure the wattage, amperage and
frequency requirements are satisfactorily supplied by the
generator for operating the equipment.
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.
Motors and motor-driven
equipment draw much greater
current for starting than during
operation.
NOTE
If wattage is not given on the equipment's
name plate, approximate wattage may be
determined by multiplying nameplate
voltage by the nameplate 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. See Table 6.
WATTS = VOLTAGE x AMPERAGE

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.
The power factor of this generator is 0.8. See Table 5 below
when connecting loads.
When connecting a fluorescent or mercury lamp, a
capacity of up to the generating set’s rated output (kW)
multiplied by 0.6 can be used.

DANGER - EXPLOSION/FIRE HAZARDS
Fuel spillage on a hot engine can cause a fire or explosion.
If fuel spillage occurs, wipe up the spilled fuel completely
to prevent fire hazards. NEVER smoke around or near the
generator.
Lubrication Oil
Fill the engine crankcase with lubricating oil through the filler
hole, but DO NOT overfill. Make sure the generator is level.
Also verify that the oil level is maintained between the two
notches (Figure 29) on the dipstick. See Table 11 for proper
selection of engine oil.
REFILLING THE FUEL SYSTEM
The DCA300SSK series generators may (if equipped with a
trailer or skid) have a double fuel tank system (Figure 30),
which consists of an internal generator fuel tank, and a
trailer mounted fuel tank. It is also possible the generator
can be equipped with a skid mounted fuel tank (Figure 31).
The skid type fuel system does not use the internal generator
fuel tank.
Use the instructions in this section that applies to your type
of fuel tank system.
Figure 29. Engine Oil Dipstick
When checking the engine oil, be sure to check if the oil is
clean. If the oil is not clean, drain the oil by removing the oil
drain plug, and refill with the specified amount of oil as outlined
in the Komatsu Engine Owner's Manual. Oil should be
warm before draining.
ALWAYS fill the fuel tank with clean and fresh #2 diesel
fuel. DO NOT fill the fuel tanks beyond their capacities.
Pay attention to the fuel tank capacity when replenishing
fuel. The fuel tank cap must be closed tightly after filling.
Handle fuel in a safety container. If the container does not
have a spout, use a funnel. Wipe up any spilled fuel
immediately.

Coolant (Ethylane Glycol [Green] / Water — 50/50 mix)
Use only drinkable tap water. If hard water or water with
many impurities is used, the inside of the engine and radiator
may become coated with deposits and cooling efficiency
will be reduced.
When the antifreeze is mixed with
water, the antifreeze mixing ratio
must be less than 50%.
NOTE
Cleaning the Radiator
An anticorrosion additive added to the water will help prevent
deposits and corrosion in the cooling system. See the engine
manual for further details.
The engine may overheat if the radiator fins become
overloaded with dust or debris. Periodically clean the radiator
fins with compressed air. Cleaning inside the machine is
dangerous, so clean only with the engine turned off and the
negative battery terminal disconnected.
WARNING - BURN HAZARDS
If adding coolant/antifreeze mix to the
radiator, DO NOT remove the radiator cap
until the unit has completely cooled.The
possibility of hot! coolant exists which
can cause severe burns.
Air Cleaner
Periodic cleaning/replacement is necessary. Inspect it in
accordance with the Komatsu Engine Owner's Manual.
Fan Belt Tension
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
Komatsu 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 11 for engine and radiator, coolant capacities. Make
sure the coolant level in the recovery tank is always between
the "H" and the "L" markings.

DCA-300SSK SERIES — PRE-SETUP
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.
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.
NOTE
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.
CAUTION - BATTERY SERVICING SAFETY
Inadequate battery connections may cause poor starting
of the generator, and create other malfunctions.
Alternator
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.
The polarity of the alternator is negative grounding type. When
an inverted circuit connection takes place, the circuit will be
in short circuit instantaneously resulting the alternator failure.
Battery Cable Installation
DO NOT put water directly on the alternator. Entry of water
into the alternator leads an electrolyte corrosion causing an
alternator failure.
ALWAYS be sure the battery cables (Figure 39) are properly
connected to the battery terminals as shown below. The
RED cable is connected to the positive terminal of the battery,
and the BLACK cable is connected to the negative terminal
of the battery.
Before charging the battery with an external electric source,
be sure to disconnect the battery cables.
Wiring
Inspect the entire generator for bad or worn electrical wiring
or connections. If any wiring or connections are exposed
(insulation missing) replace wiring immediately.
CAUTION - BATTERY SERVICING SAFETY
ALWAYS disconnect the negative terminal FIRST and
reconnect negative terminal LAST.
Piping and Hose Connection
Inspect all piping, oil hose, and fuel hose connections for
wear and tightness.Tighten all hose clamps and check hoses
for leaks.
If any hose (fuel or oil) lines are defective replace them
immediately.
If applicable perform the following:
Figure 39. Battery Connections
■
Apply commercial power to the internal battery charger
receptacle (to ensure good starting) via commercial power.
An external power cord will be required.This capability is an
option.
When connecting battery do the following:
1. NEVER connect the battery cables to the battery
terminals when the ignition switch is in either the Pre-
Heat, RUN, or START position. ALWAYS make sure
that the ignition switch is in the STOP position when
connecting the battery.
■
Apply commercial power to the jacket water heater
receptacle (not necessary for warm climates) via commercial
power.An external power cord will be required.This capability
is an option.
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.

condense. This can be reduced by always keeping the tank
as full as possible.
1. Loosen wing bolt, remove dust cup, then remove wing
nut and take out element.
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.
To restart after running out of fuel, turn the key switch to the
“START” position for 15-30 seconds. Try again, if needed.
This unit is equipped with an automatic air bleeding system.
2. Clean the inside of the body and cover using a damp
cloth.
3. Blow dry with compressed air (0.69Mpa {7kgf.cm2,
99.4 PSI} maximum) against the side of the element
along the pleats. Then blow dry against outside along
the pleats, then against inside again.
4. Remove one seal each time the element is cleaned.
Service Daily
5. Replace the outer element after cleaning it 6 times or
after one year. Replace the outer element if indicator is
red even after cleaning it.
If engine is operating in very dusty and dry grass conditions,
a clogged air cleaner will result in high fuel consumption,
loss of power and excessive carbon buildup in the
combustion chamber.
6. Check the inner cylinder element clamping nut for
looseness, and retighten if necessary.
Cleaning the Fuel Strainer
7. If seal washer is damaged or the threads of wing nut are
damaged, replace.
Clean the fuel strainer if it contains dust or water. Remove
dust or water in the strainer cap and wash it in diesel. Securely
fasten the fuel strainer cap so that fuel will not leak. Check
the fuel strainer every 200 hours of operation or once a month.
8. Remove evacuator valve and clean it with compressed
air. Reinstall.
Check Oil Level
Inner element (if equipped)
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 29.
1. Remove the cover and outer element, then remove the
inner element.
2. Cover the air connector opening (outer side) with clean
cloth or cloth tape.
3. Clean the inside of the body. Remove air connector

4. After draining the coolant, close drain plugs and fill with
tap water.
5. When the water level is near the mouth of the water
filler, open drain plugs and start the engine, and run at
low idling. Keep the engine running at low idling and
flush the radiator for about 10 minutes.
5. Tighten drain plug. Clean the filter holder, fill the new
filter cartridge with clean engine oil, coat the packing
and thread of the new filter cartridge with engine oil,
then install it to the filter holder. Tighten until the gasket
surface contacts the seal surface of the filter holder,
then tighten it a further 3/4 to 1 turn.
6. Adjust the flow of the water flowing in and draining out to
ensure that the radiator is always full during the flushing
operation. While flushing water through the system,
watch carefully the water inlet hose does not come out
of the radiator filler port.

Brakes
Hydraulic Surge Brakes
Trailer brakes should be inspected the first 200 miles of Hydraulic surge brakes should not require any special
operation. This will allow the brake shoes and drums to seat attention with the exception of routine maintenance such as
properly. After the first 200 mile interval, inspect the brakes shoe and lining replacement. Brake lines should be
every 3,000 miles. If driving over rough terrain, inspect the periodically checked for cracks, kinks, or blockage.
brakes more frequently.
Figure 74 displays the major hydraulic surge brake
components that will require inspection and maintenance.
Use Table 14 as a basic trouble shooting guide when brake
problems occur. Please inspect these components as
required using steps 1 through 6 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.
4. With a screwdriver or standard adjusting tool, rotate the
star wheel of the adjuster assembly to expand the brake
shoes.
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.
Figure 74. Hydraulic Brake Components
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.
Periodically check and test the surge “actuator ” to make
sure that it is functioning correctly. Never use an undersize
actuator.
8. Repeat steps 1 through 7 on the remaining brakes.
