REPORTING SAFETY DEFECTS
If you believe that your vehicle has a defect that could cause a crash or could
cause injury or death, you should immediately inform the National Highway
Traffic Safety Administration (NHTSA) in addition to notifying Multiquip at
1-800-421-1244.
If NHTSA receives similar complaints, it may open an investigation, and if it
finds that a safety defect exists in a group of vehicles, it may order a recall and
remedy campaign. However, NHTSA cannot become involved in individual
problems between you, your dealer, or Multiquip.
To contact NHTSA, you may either call the Vehicle Safety Hotline toll-free at
1-888-327-4236 (TTY: 1-800-424-9153), go to http://www.nhtsa.dot.gov; or

Figure 2. Typical Generator Grounding Application
PAGE 14 — DCA180SSI/DCA180SSIU 60 HZ GEN. • OPERATION AND PARTS MANUAL — REV. #1 (08/02/10)
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
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.
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 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.
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.
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.
3. NEC article 250-52(c) specifies that the earth ground rod
should be buried a minimum of 8 ft. into the ground.
NOTICE
When connecting the generator to any buildings
electrical system ALWAYS consult with a licensed
electrician.

• Voltage Change-over Board
OUTPUT TERMINAL PANEL
The “Output Terminal Panel” is provided with the following:
Three 120/240V output receptacles (CS-6369), 50A
Three auxiliary circuit breakers, 50A
Two 120V output receptacles (GFCI), 20A
Two GFCI circuit breakers, 20A
Five output terminal lugs (3Ø power)
Battery Charger (Optional)
Water Heater (Optional)
OPEN DELTA EXCITATION SYSTEM
Each 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
These generators are powered by a 6 cylinder, water
cooled, direct injection, turbocharged ISUZU 6JK1X diesel
engine. This engine is 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.

of status LED's (inse t), tha t
when lit, indicate that an engine
ma lfun ction (fault ) has been
detected. When a fault has been
detected the engine controller will
evaluate the fault and all major
faults will shutdown the generator. During cranking
cycle, the ECU will attempt to crank the engine for 10
seconds before disengaging.
If the engine does not engage (start) by the third
attempt, the engine will be shutdown by the engine
controller’s Over Crank Protection mode. If the engine
engages at a speed (RPM's) that is not safe, the
controller will shutdown the engine by initializing the
Over Speed Protection mode.
Also the engine controller will shut down the engine in
the event of low oil pressure, high coolant temperature,
low coolant level, and loss of magnetic pickup. These
conditions can be observed by monitoring the LED status
indicators on the front of the controller module.

sending unit. This is considered a major fault.
C. High Coolant Temperature — Indicates the engine
temperature has exceeded 230°F (110°C). The engine
temperature is detected using variable resistive values
from the temperature sending unit. This is considered
a major fault.
D. Overcrank Shutdown — Indicates the unit has
attempted to start a pre- programmed number of
times, and has failed to start. The number of cycles
and duration are programmable. It is pre-set at 3
cycles with a 10 second duration. This is considered
a major fault.
E. Overspeed Shutdown — Indicates the engine is
running at an unsafe speed. This is considered a
major fault.
F. Engine Running — Indicates that engine is running
at a safe operating speed.
