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 1-888327-4236 (TTY: 1-800-424-9153), go to http://www.nhtsa.dot.gov; or write to:

CONNECTING THE GROUND
Consult with local Electrical and Safety Codes for proper
connection based on condition of use.
EXAMPLE of how to ground the unit if the condition
of use requires such a device:
The nut and ground terminal on the generator should
always be used to connect the generator to a suitable
ground when required. The ground cable should be #8
size wire minimum.
At the generator, connect the terminal of the ground cable
between the lock washer and the nut (Figure 2) and tighten
the nut fully. Connect the other end of the ground cable to
a suitable earth ground (ground rod).

INSTALLATION
OUTDOOR INSTALLATION
If possible 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.
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.
WARNING
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 - 8 AWG (5.3 mm2)
b. Aluminum - 6 AWG (8.4 mm2)
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 gas 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.
PLACEMENT
The generator should always be placed on a flat level
surface when it is running. DO NOT place the generator
on slopes, the possibility exists that the generator could

the proper amount of coolant.
Oil Pressure Warning Alarm
This unit is equipped with an oil pressure switch that detects
low oil pressure. If the lubricating oil pressure of this unit
should become abnormally low, the oil pressure switch
signals the emergency relay to shutdown the engine. If
this condition should occur, please refer to the engine
troubleshooting table in this manual.
Idle Control Switch
The DA7000SSA2/SSA2GH generator is provided with
an automatic idle (engine) control capability for noise
suppression and fuel cost reduction. The automatic idle
control feature automatically engages under a no-load
condition when the switch is in the ON position.
With AC loads of more than 100W (such as lighting
equipment, motor-powered tools, submersible water
pumps, etc.), the engine runs at high speed. When a no load
condition is produced, the engine automatically slows down.
Turn the idle control switch to the “ON” (up) position when
AC loads drawing more than 150W are connected. Turn
the idle control switch to the “OFF” (down) position when
AC loads drawing less than 100W or when a magnetic

Excitation System
The DA7000SSA2/SSA2GH generators use a brushless
exciter to create rated output electricity. This system will
use the mechanical energy generated by the 3600 RPM
engine to spin the rotor (or armature) inside the generator
(or alternator end).
Excitation current is sourced from the battery to the
excitation winding in the stator. Current applied to this coil
creates a magnetic field. The rotating armature within the
stator is then induced with AC current.
Engine
The DA7000SSA2/SSA2GH generators are powered by a
water-cooled, 4-cycle KUBOTA diesel engine. This engine
is designed to meet every performance requirement of the
generator. Reference Table 2, engine specifications.
In keeping with Multiquip's policy of constantly improving

LOAD APPLICATIONS
Single Phase Load — 60 Hz
Always be sure to check the nameplate on the generators
and equipment to insure the wattage, amperage and
frequency requirements are satisfactorily supplied by the
generators for operating the equipment.
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.
NOTICE
If wattage is not given on the equipment's name plate,
approximate wattage may be determined by multiplying
nameplate voltage by the nameplate amperage
WATTS = VOLTAGE x AMPERAGE
The power factor of this generators is 1.0 See Table 4 below
when connecting loads.
Table 4. Power Factor By Load
To determine the running wattage for your load, multiply the
running wattage as indicated by steps 1, 2, and 3 below:
1. INCANDESCENT LOADS
Lights, heaters and similar appliances.
total the running wattage and multiply by 1.
Example:
29 light bulbs @ 100W each = 2.9 kW

OPERATION
Before Starting the Engine
CAUTION
The engine’s exhaust contains harmful emissions.
ALWAYS have adequate ventilation when operating.
Direct exhaust away from nearby personnel.
NOTICE
The DA7000SSA2/SSA2GH generator is equipped with
a GFCI sensing module. The purpose of this module is
to sense a ground fault during operation of the generator
and open the main breaker once the ground fault has
been detected.
Multiquip recommends that the GFCI sensing module
be tested before each use of the generator. Refer to the
maintenance section of this manual for testing of the
GFCI module.
1. Open the cabinet door and turn the fuel cock lever
(Figure 18) to the “ON” position.
3. NEVER start the engine with the main circuit breaker
in the ON position. Always place circuit breaker (Figure 20)
in the OFF position before starting.
Figure 20. Main Circuit Breaker (OFF)
4. NEVER start the engine with the auxiliary circuit
breakers in the ON position. Always place circuit
breakers (Figure 21) in the OFF position before starting
the engine.

2. NEVER operate the generator with the doors open
(Figure 19). Operation with the doors open may cause
insufficient cooling of the unit, and engine damage may
result. Close the doors for normal operation.
Starting the Engine
1. Insert the key into the starter switch (Figure 22) and
turn it to the “RUN” position. Check to see that the oil
pressure and charge Lights on the "Warning Lamp Unit
Display" are lit. If either light is not lit, check the system
and wiring (refer to the Engine Operation Manual).
Figure 22. Starter Switch
2. Turn the ignition key to the HEAT position. When the
preheat light goes off, turn the key to the START
position to start the engine. As soon as the engine
starts, release the key. The key will automatically return
to the RUN position.

4. If the engine does not start within 10 seconds after the
key is turned to the START position, wait for about 30
seconds and repeat the procedure as described in
steps 1-3.
5. When the engine starts, the oil pressure light and
charge light should go out. If these lights stay on,
immediately stop the engine and check the system and
wiring (refer to the Engine Operation Manual).
6. Let the engine idle for five minutes with the Idle Control
Switch (Figure 23) placed in the ON position.
Figure 23. Idle Control Switch (ON)
NOTICE
Placing the idle control switch (Figure 23) in the OFF
position allows the engine to operate at a maximum
speed of about 3600 RPM's.
2. Place auxiliary circuit breakers (Figure 25) in the ON
position.
Figure 25. Auxiliary Circuit Breakers (ON)
3. Read the voltmeter on front panel of generator (Figure
26) and verify that 120 VAC is displayed. Using an
external voltmeter as shown in Figure 26, verify that
120 VAC is present at the 120V twist-lock and duplex
receptacles.

When the idle control switch is placed in the up position
(ON), the generator will run at idle speed (2200 RPM's)
until a load is applied, at that time the engine speed
will increase to 3600 RPM's as long as a load is being
applied.
When the load is not in use, the engine speed will drop
back to the idle mode after about 3 seconds.
Output Voltage Verification
1. Place main circuit breaker (Figure 24) in the ON
position.
