DCA-70SSJU2 (60 Hz) — 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.
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.
To guard against electrical shock and possible damage to
the equipment, it is important to provide a good EARTH
ground. See Figure 4 for a typical grounding configuration.
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.
Foreign materials such as dust, sand, lint and abrasive
materials have a tendency to cause excessive wear to
engine and alternator parts.
1. Use one of the following wire types to connect the
generator to earth ground.
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
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.
NEC articles 250-64(b) and 250-66 set the following
grounding requirements:
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.
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

DCA-70SSJU2 (60 Hz) — LOAD APPLICATION
Single Phase Load
Three 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.
When calculating the power requirements for 3-phase power
use the following equation:
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
WATTS = VOLTAGE x AMPERAGE
NOTE
NOTE
If 3Ø load (kVA) is not given on
the equipment nameplate,
approximate 3Ø load output
maybe determined by multiplying
voltage by amperage by 1.732.

How to Read the Output Terminal Gauges.
The gauges and selector switches on the control panel
DO NOT effect the generator output. They are provided to
help observe how much power is being supplied at the
Output terminals lugs.
Before taking a reading off either gauge, set the Voltage
Selector Switch (Figure 17) to the position which produces
the required voltage (For example, for 3Ø 240V,
choose the center 3Ø 240/
139V position on the voltage selector switch.)
Reading Amperage
To determine the amperage at a terminal lug, set the
AC Ammeter Change-Over Switch to the appropriate
setting (Figure 20) to activate the AC Ammeter Gauge
(Figure 21) and read the available amperage at the terminal
lug.
For example, to measure the amperage at the U
terminal lug, set the AC Ammeter Change-Over Switch to
U and read the AC Ammeter Gauge.

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 14 as a general maintenance
guideline Engine Side (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
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.

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 57 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 15 as shown 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 56) 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 57. 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.

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 58) 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 17.
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 16 (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 59). 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.
