NOTE
This Owner's Manual has been
developed to provide complete
instructions for the safe and
efficient operation of the
MQ Power Model DCA-15SPX4
Whisperwatt™ Generator.
Before using this generator, ensure that the operating
individual has read and understands all instructions in
this manual.
HAZARD SYMBOLS
Potential hazards associated with the operation of this
equipment will be referenced with "Hazard Symbols" which
appear throughout this manual, and will be referenced in
conjunction with Safety "Message Alert Symbols".
WARNING - LETHAL EXHAUST GASES
Gasoline engine exhaust gases contain
poisonous carbon monoxide. This gas is
colorless and odorless, and can cause
DEATH if inhaled. NEVER operate this
equipment in a confined area or enclosed structure that
does not provide ample free flow air.
WARNING - EXPLOSIVE FUEL
SAFETY MESSAGE ALERT SYMBOLS
The three (3) Safety Messages shown below will inform you
about potential hazards that could injure you or others. The
Safety Messages specifically address the level of exposure
to the operator, and are preceded by one of three words:
DANGER, WARNING, or CAUTION.
DANGER
You WILL be KILLED or SERIOUSLY injured if you
do not follow directions.
WARNING
Diesel fuel is extremely flammable, and
its vapors can cause an explosion if
ignited. DO NOT start the engine near
spilled fuel or combustible fluids.
DO NOT fill the fuel tank while the engine
is running or hot.
DO NOT overfill tank, since spilled fuel could ignite if it
comes into contact with hot engine parts or sparks from
the ignition system. Store fuel in approved containers, in
well-ventilated areas and away from sparks and flames.
NEVER use fuel as a cleaning agent.
WARNING - BURN HAZARDS
You COULD be KILLED or SERIOUSLY injured if
you do not follow directions.
CAUTION
Engine components can generate extreme
heat. To prevent burns, DO NOT touch these
areas while the engine is running or
immediately after operations. NEVER
operate the engine with heat shields or heat
guards removed.
You CAN be injured if you do not follow directions
DANGER - ELECTROCUTION HAZARDS
During operation of this generator, there
exists the possibility of electrocution,
electrical shock or burn, which can cause
severe bodily harm or even DEATH!
PAGE 8 — DCA-15SPX4— OPERATION MANUAL — REV. #0 (02/17/09)
DCA-15SPX4 — SAFETY MESSAGE ALERT SYMBOLS
WARNING - ROTATING PARTS
NEVER operate equipment with covers,
or guards removed. Keep fingers, hands,
hair and clothing away from all moving
parts to prevent injury.
CAUTION - ACCIDENTAL STARTING
ALWAYS place the engine ON/OFF
switch (MPEC) in the OFF/RESET
position when the generator is not in use.
CAUTION - OVER-SPEED CONDITIONS
NEVER tamper with the factory settings
of the engine governor or settings.
Personal injury and damage to the engine
or equipment can result if operating in
speed ranges above maximum allowable.
CAUTION - RESPIRATORY HAZARDS
ALWAYS wear approved respiratory
protection.
CAUTION - SIGHT AND HEARING HAZARDS
ALWAYS wear approved eye and
hearing protection.
CAUTION - EQUIPMENT DAMAGE MESSAGES
Other important messages are provided throughout this
manual to help prevent damage to your generator, other
property, or the surrounding environment.
CAUTION - ENGINE LOAD (WET-STACKING)
NOTE
This generator, other property, or
the surrounding environment
could be damaged if you do not
follow instructions.
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 turbocharges, and reduce the operating
performance.
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.
Wet stacking does 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.

Towing and Transporting Safety
To reduce the possibility of an accident while transporting
the generator on public roads, always make sure the trailer
that supports the generator and the towing vehicle are in
good operating condition and both units are mechanically
sound.
The following list of safety precautions should be followed
when towing your generator:
CAUTION - FOLLOW TOWING REGULATIONS
Check with your local county or state safety towing
regulations, in addition to meeting Department of
Transportation (DOT) Safety Towing Regulations, before
towing your generator.
■ ALWAYS shutdown engine before transporting.
■ Drain fuel from generator fuel tank before towing.
■ If generator is mounted on a trailer, make sure trailer
complies with all local and state safety transportation
laws. Follow the listed Towing & Transporting Safety
guidelines for basic towing techniques.
■ Make sure the hitch and coupling of the towing vehicle
are rated equal to, or greater than the trailer "gross vehicle
weight rating.”
■ DOT Requirements include the following:
 Connect and test electric brake operation.
 Secure portable power cables in cable tray with tie
wraps.
■ The maximum speed for highway towing is 55 MPH
unless posted otherwise. Recommended off-road towing
is not to exceed 15 MPH or less depending on type of
terrain.
■ Place chock blocks underneath wheel to prevent rolling,
while parked.
■ Use the trailer’s swivel jack to adjust the trailer height to
a level position while parked.
■ Avoid sudden stops and starts. This can cause skidding,
or jack-knifing. Smooth, gradual starts and stops will
improve towing.
■ Avoid sharp turns.
■ Trailer should be adjusted to a level position at all times
when towing.
■ Raise and lock trailer wheel stand in up position when
transporting.
■ The maximum speed for highway towing is 55 MPH
unless posted otherwise. Recommended off-road towing
is not to exceed 15 MPH or less depending on type of
terrain.
■ Place support blocks underneath the trailer’s bumper to
prevent tipping, while parked.
■ Avoid sharp turns to prevent rolling.
■ DO NOT transport generator with fuel in tank.
■ ALWAYS inspect the hitch and coupling for wear. NEVER
tow a trailer with defective hitches, couplings, chains etc.
■ Check the tire air pressure on both towing vehicle and
trailer. Trailer tires should be inflated to 50 psi cold.
Also check the tire tread wear on both vehicles.
NOTE
For more saftey tips, see the trailer saftey
guidelines section in this manual.
■ ALWAYS make sure the trailer is equipped with a "Safety

PAGE 16 — DCA-15SPX4— OPERATION MANUAL — REV. #0 (02/17/09)
DCA-15SPX4 — 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.
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.
Foreign materials such as dust, sand, lint and abrasive
materials have a tendency to cause excessive wear to
engine and alternator parts.
CAUTION - EXHAUST HAZARD
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.
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.
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.
a. Copper - 10 AWG (5.3 mm2) or larger.
b. Aluminum - 8 AWG (8.4 mm2) or larger.
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 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.
NOTE
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.

Open Delta Excitation System
The generator is equipped with the state of the art "OpenDelta" 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.
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.
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.
Engine
The DCA-15SPX4 is powered by a 4 cylinder, water cooled,
Kubota Model V2203-M diesel engine. This engine is
designed to meet every performance requirement for the
generator. Reference Table 1 for engine specifications.
In keeping with MQ Power's policy of constantly improving
its products, the specifications quoted herein are subject to
change without prior notice.
Electric Governor System
The electric governor system controls the RPMs of the engine. When the engine demand increases or decreases, the
governor system regulates the frequency variation to ±.25%.
Extension Cables
When electric power is to be provided to various tools or
loads at some distance from the generator, extension cords
are normally used. Cables should be sized to allow for
distance in length and amperage so that the voltage drop
between the generator and point of use (load) is held to a
minimum. Use the cable selection chart (Table 6) as a guide
for selecting proper extension cable size.

DCA-15SPX4 — LOAD APPLICATION/MAXIMUM AMPERAGE
Single 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.
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.
If wattage is not given on the
equipment's name plate,
approximate wattage may be
determined by multiplying
nameplate voltage by the
nameplate amperage.
NOTE
Motors and motor-driven
equipment draw much greater
current for starting than during
operation.
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.
■ 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.
■ 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.
■ When connecting an electric drill or other power tools,
WATTS = VOLTAGE x AMPERAGE
The power factor of this generator is 0.8. See Table 5 below
when connecting loads.
Table 5. Power Factor By Load

General Inspection
Service Daily
Prior to each use, the generator should be cleaned and
inspected for deficiencies. Check for loose, missing or
damaged nuts, bolts or other fasteners. Also check for fuel,
oil, and coolant leaks. Use Table 11 as a general engine
maintenance guideline (Refer to the Engine Instruction
Manual).
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.
Air Cleaner
Add diesel fuel (the grade may vary according to season
and locations).
Every 250 hours: Remove air cleaner element and clean the
heavy duty paper element with light spray of compressed
air. Replace the air cleaner as needed.
Air Cleaner with Dust Indicator (If Equipped)
This indicator is attached to the air cleaner. When the air
cleaner element is clogged, air intake restriction becomes
greater and the dust indicator signal shows RED meaning
the element needs changing or service. After changing the
air element, press the dust indicator button to reset the
indicator.
Fuel Addition
Removing Water from the Fuel Tank
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.
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.

Jacket Water Heater and Internal Battery Charger
120 VAC Input Receptacles (OPTIONAL)
This generator can be optionally equipped with two 120 VAC,
20 amp input receptacles located on the output terminal
panel.
The purpose of these receptacles is to provide power via
commercial power to the jacket water heater and internal
battery charger.
These receptacles will ONLY function when commercial
power has been supplied to them (Figure 36). To apply
commercial power to these receptacles, a power cord of
adequate size will be required (See Table 6).
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 an power cord of
adequate size.
NOTE
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
generator will be used in cold climates it is always a good
idea to apply power to the jacket water heater at all times. To
apply power to the jacket water heater simply apply power to
the jacket water heater receptacle via commercial power
using an power cord of adequate size.

DCA-15SPX4 — TRAILER MAINTENANCE
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.
Figure 37 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 12 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.
8. Repeat steps 1 through 7 on the remaining brakes.
Hydraulic Surge Brakes
Hydraulic surge brakes (Figure 37) 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 37. 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.

DCA-15SPX4 — TRAILER MAINTENANCE
Tires/Wheels/Lug Nuts
Tires and wheels are a very important and critical
components of the trailer. When specifying or replacing the
trailer wheels it is important the wheels, tires, and axle are
properly matched.
CAUTION - EYESIGHT HAZARD
Suspension
The leaf suspension springs and associated components
(Figure 38) should be visually inspected every 6,000 miles
for signs of excessive wear, elongation of bolt holes, and
loosening of fasteners. Replace all damaged parts
(suspension) immediately. Torqued suspension components
as detailed in Table 14.
ALWAYS wear safety glasses when
removing or installing force fitted parts.
Failure to comply may result in serious
injury.
CAUTION - REPAIRING TRAILER WHEELS
DO NOT attempt to repair or modify a wheel. DO NOT
install in inner tube to correct a leak through the rim. If the
rim is cracked, the air pressure in the inner
tube may cause pieces of the rim to
explode (break off) with great force and
cause serious eye or bodily injury.
Tire Wear/Inflation
Tire inflation pressure is the most important factor in tire life.
Pressure should be checked cold before operation DO NOT
bleed air from tires when they are hot!. Check inflation
pressure weekly during use to insure the maximum tire life
and tread wear.
Table 13 (Tire Wear Troubleshooting) will help pinpoint the
causes and solutions of tire wear problems.

Lug Nut Torque Requirements
It is extremely important to apply and maintain proper wheel
mounting torque on the trailer. Be sure to use only the
fasteners matched to the cone angle of the wheel. Proper
procedure for attachment of the wheels is as follows:
1. Start all wheel lug nuts by hand.
2. Torque all lug nuts in sequence (see Figure 39). DO NOT
torque the wheel lug nuts all the way down. Tighten each
lug nut in 3 separate passes as defined by Table 15.
3. After first road use, retorque all lug nuts in sequence.
Check all wheel lug nuts periodically.
