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.

Figure 2. Typical Generator Grounding Application
PAGE 16 — DCA-10SPX4— OPERATION AND PARTS MANUAL — REV. #0 (02/17/09)
DCA-10SPX4 — INSTALLATION
Outdoor Installation
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.
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.
Indoor Installation
Generator Grounding
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.
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 mm
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.
2
) or larger.
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.
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.
NOTE
When connecting the generator
to any buildings electrical
system ALWAYS consult with
a licensed electrician.

DCA-10SPX4 — GENERAL INFORMATION
DCA-10SPX4 Whisperwatt™ Series Familiarization
Generator
The MQ Power Model DCA-10SPX4 is a 10 kW
generator
(Figure 3) that is 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.
Generator Control Panel
The “Engine Operating Panel” is provided with the following:
Open Delta Excitation System
The generator is equipped with the state of the art "
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.

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 "
according the demands of the required load.
Engine
The DCA-10SPX4 is powered by a 3 cylinder, water cooled,
Kubota Model D1503-M diesel engine
designed to meet every performance requirement for the
generator. Reference Table 2 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.

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.

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 33). 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.
