DCA-70SSJU— 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.

CAUTIONCAUTION

:

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.

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.

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.

Explanation of Chart:

This section is to provide the user with trailer service and
maintenance information. The service and maintenance
guidelines referenced in this section apply a wide range of
trailers. Remember periodic inspection of the trailer will en­sure safe towing of the equipment and will prevent damage
to the equipment and personal injury.

It is the purpose of this section to cover the major mainte­nance components of the trailer. The following trailer com­ponents will be discussed in this section:



Brakes



Tires



Lug Nut Torquing

Use the following definitions when reading Table 2.

1. Fuel Cell - Provides an adequate amount of fuel for the
equipment in use. Fuel cells must be empty when trans­porting equipment.

2. Braking System - System employed in stopping the
trailer. Typical braking systems are electric, surge, hy­draulic, hydraulic-surge and air.

:

ALWAYS make sure the trailer is in good

operating condition. Check the tires for
proper inflation and wear. Also check the
wheel lug nuts for proper tightness.

Open Delta Excitation System

The DCA-70SSJU Series generator is equipped with the state
of the art "
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 ot
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 "

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.

Mechanical Governor System

The mechanical governor system control the RPM of the
engine. When the engine demands increase or decrease, the
mechanical governor system regulates the frequency varia­tion to ±.5%. The electronic governor option increases
frequency variation to ±0.25%.

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 5) as a guide for selecting proper
extension cable size.

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.

DO NOT over fill. Check to see whether the battery cables
are loose. Poor contact may result in poor starting or
malfunctions.
Coating the terminals with an approved battery terminal
treatment compound. Replace battery with only
recommended type battery. The battery type used in this
generator is BCI Group 27.

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.

Battery Cable Installation
ALWAYS be sure the battery cables (Figure 43) 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.

Always

keep the terminals firmly tightened.

When connecting battery do the following:

1. NEVER connect the battery cables to the battery
terminals when the
Heat, RUN, or START position. ALWAYS make sure
that the ignition switch is in the STOP position when
connecting the battery.

2. Place a small amount of battery terminal treatment
compound around both battery terminals. This will ensure

General Inspection

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.

Engine Side (Refer to the Engine Instruction Manual)

Air Cleaner

Every 50 hours: Remove air cleaner element and clean the heavy
duty paper element with kerosene, or foam element with liquid
detergent and hot water. Wrap foam element in a cloth and
squeeze dry. For heavy duty paper element, wipe excess
kerosene with towel.

Service Daily

If the engine is operating in very
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

Fuel Addition

Add diesel fuel (the grade may vary according to season and
locations). Always pour through the mesh filter.

Removing Water from the Fuel Tank

After prolonged use, water and other impurities accumulate in

DCA-70SSJU SERIES — MAINTENANCE

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 switch to the
“ON” position for 15-30 seconds. Try again, if needed. This
unit is equipped with an automatic air bleeding system.

Cleaning the Fuel Strainer

Clean the fuel strainer if it contains dust or water. Remove
dust or water in the strainer cap and wash it in gasoline.
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.

Check Oil Level

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 32.

Flushing Out Radiator and Replacing Coolant



Open both cocks located at the crankcase side and at
the lower part of the radiator and drain coolant. Open the
radiator cap while draining. Remove the overflow tank
and drain.



Check hoses for softening and kinks. Check clamps for
signs of leakage.



Flush the radiator by running clean tap water through
radiator until signs of rust and dirt are removed. DO NOT
clean radiator core with any objects, such as a
screwdriver.



Tighten both cocks and replace the overflow tank.



Replace with coolant (Table 12 for correct mixture).



Close radiator cap tightly.

Replacing Oil Filter



Detach the oil filter by loosening center bolt and remove
the element together with the filter body.



Apply a film of oil to the gasket for the cartridge.



Install the filter body together with the element and fix
them by tightening the center bolt.



After the oil cartridge has been replaced, the engine oil
will drop slightly. Run the engine for a while and check
for leaks before adding more oil if needed. Clean
excessive oil from engine.

Replacing Fuel Filter



Replace the fuel filter cartridge with new one every 400
hours or so.



Loosen the drain plug at the lower top of the fuel filter.
Drain the fuel in the fuel body together with the mixed
water. DO NOT spill the fuel during disassembly.



Vent any air.

Feed Pump Strainer Cleaning

The strainer is incorporated in the feed pump inlet side joint
bolt. Clean the strainer with compressed air and rinse it in
the fuel oil.

Generator Storage

For longe term storage of the generator the following is
recommended:



Fill the fuel tank completely. Treat with a fuel stabilizer
if necessary.



Completely drain the oil from the crankcase and refill if
necessary with fresh oil.



Clean the entire generator, internal and external.



Cover the generating set and store in a clean, dry place.



Disconnect the battery.



Make sure engine coolant is at proper level.



If generator is mounted on a trailer, jack trailer up and
place on block so tires do touch the ground or remove
tires.

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 78). DO NOT
torque the wheel lug nuts all the way down. Tighten each
lug nut in 3 separate passes as defined by Table 18.

3. After first road use, retorque all lug nuts in sequence.
Check all wheel lug nuts periodically.
