DCA-180SSV— GENERATOR DECALS
The DCA-180SSVgenerator is equipped with a number of safety decals (Figures 2 & 3). These decals are provided for
operator safety and maintenance information. The illustration below and on the preceding page show the decals as they
appear on the machine. Should any of these decals become unreadable, replacements can be obtained from your dealer.

DCA-180SSV— INSTALLATION
Figure 4. Typical Generator Grounding Application
PAGE 16 — DCA-180SSV— OPERATION AND PARTS MANUAL — REV. #1 (04/14/10)
DCA-180SSV— 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 mm2) or larger.
b. Aluminum - 8 AWG (8.4 mm2) or larger.
2. When grounding the generator (Figure 4) 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.
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.

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 "

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-180SSV— ENGINE OPERATING PANEL
The definitions below describe the controls and functions of
the DCA-220SSVU
1. Panel Light – Normally used in dark areas or at night
time. When activated, panel lights will illuminate. When
the generator is not in use be sure to turn the panel
light switch to the OFF position.
2. Panel Light Switch – When activated will turn on control
panel light.
3. Oil Pressure Gauge – During normal operation this
gauge be should read between 44 to 73 psi. (303~503
kPa). When starting the generator the oil pressure may
read a little higher, but after the engine warms up the oil
pressure should return to the correct pressure range.
4. Water Temperature Gauge – During normal operation
this gauge be should read between 189° and 216°F.
5. Charging Ammeter Gauge – Indicates the current
being supplied by the engine’s alternator which provides
current for generator’s control circuits and battery
charging system.
6. Fuel Gauge - Indicates amount of diesel fuel available.
7. Tachometer – Indicates engine speed in RPM’s for 60
Hz operation. This meter should indicate 1800 RPM’s
when the rated load is applied. In addition a built in hour
meter will record the number of operational hours that
the generator has been in use.
8. Coolant Alarm Lamp – This lamp will illuminate when
the coolant level falls below a safe operating level and
the engine will stop.
9. Auto On/Off Engine Controller (MPEC) –
This controller has a vertical row of status LED's (inset),
that when lit, indicate that an engine malfunction (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

switch is set to the MANUAL position, the generator
will start immediately.
If the generator is to be connected to a building’s AC
power source via an automatic transfer switch
(isolation), place the switch in the AUTO position. In
this position, should an outage occur, the automatic
transfer switch (ATS) will start the generator
automatically via the generator’s auto-start contacts
connected to the ATS’s start contacts. Please refer to
your ATS installation manual for further instructions for
the correct installation of the auto-start contacts of the
generator to the ATS.
