MQ GA-2.9R Familarization
General Inspection Prior to Operation
This generator has been thoroughly inspected and accepted
prior to shipment from the factory. However, be sure to check
for damaged parts or components, or loose nuts and bolts,
which could have become disloged in transit.
The
MQ Model GA-2.9R
portable lightweight power source for 60 Hz (single-phase)
vibrators, lighting facilities, power tools, submersible pumps
and other industrial and construction machinery.
This generator is powered by a 5.7 HP ROBIN air-cooled
gasoline engine. The alternator, a brushless revolving-field
type, is permanently aligned to the engine through rigid
coupling.
The generator is mounted on rubber vibration isolators that
have a steel base backplate which is attached to the
protective steel pipe carrying frame. The protective carrying
frame is made of steel tubing and fully wraps around the
generator to protect against damage.
This portable generator is supplied with a electrical
panel
. The control panel includes items as listed below.
Control Panel
The generator control panel has the following componets:
■
NEMA 5-20R, GFCI duplex receptacle, (120V, 20 amps)
■
NEMA L5-20R, twist-lock receptacle, (120V, 20 amps)
generator has been designed as a
control
Excitation System
The MQ GA-2.9R generator uses a magnet attached to a
flywheel to produce AC voltage from a lamp coil beneath
the flywheel. As the magnet passes the coil it produces
approximately 19-22 AC volts.
This voltage (19-22 VAC) is then sent to the control box that
contains three rectifying diodes:
z
Excitation (diode 1)
z
Battery (diode 2)
z
Slow Down (diode 3)
The AC voltage will pass through the excitation diode that
converts the voltage to DC power.
This DC power is then sent to the excitation windings housed
within the main windings commonly called the "stator".
This voltage is then transferred into the rotor through
induction. The rotor contains two diodes within it which rectify
the DC voltage and send it out through the main windings,
as AC voltage.

MQ GA-2.9R— LOAD APPLICATION
Single Phase Load
Always be sure to check the nameplate on the generator
and equipment to insure the wattage, amperage and
frequency requirements are satisfactorily supplied by the
generator 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.
If wattage is not given on the equipment's
NOTE
WATTS = VOLTAGE x AMPERAGE
The power factor of this generator is 1.0 See Table 2 below
when connecting loads.
name plate, approximate wattage may be
determined by multiplying nameplate
voltage by the nameplate amperage.
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
use a 3 KW generator.
2.SMALL MOTORS
Drills and other small power tools.
Total the running wattage and multiply by 2.
Example:
A 1 inch drill runs at 1 KW
use a 2 KW generator.
3.LARGE MOTORS
Submersible pumps, table saws etc.
Total the running wattage and multiply by 3.
Example:
A conveyor belt runs at 8 KW
use a 24 KW generator.

Adding fuel to the tank should be done only when
the engine is stopped and has had an opportunity
to cool down. In the event of a fuel spill, DO NOT attempt to start
the engine until the fuel residue has been completely wiped up,
and the area surrounding the engine is dry. If generator is placed
in a truck bed with a plastic liner, REMOVE generator from truck
bed and place on ground (Figure 4) to refuel. This possibility
exist of

MQ GA-2.9R — INSTALLATION
Outdoor Installation
Install the generator in a area that is free of
bystanders
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.
Pay close attention to ventilation when
operating the generator inside tunnels and
caves. The engine exhaust contains
noxious elements.

overhead obstructions
CAUTIONCAUTION

. Make sure the

Indoor Installation
,
Exhaust gases from gasoline 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.
Eliminate the danger of deadly carbon monoxide gas.
Remember that exhaust fumes from any gasoline engine
are very poisonous if discharged in a closed room, but
harmless if allowed to mix with the outside air. If the generator
is installed indoors, you must make provisions for venting
the engine exhaust to the outside of the building.
Generator Grounding
To guard against electrical shock and possible damage to
the equipment, it is important to provide a good EARTH
ground. Always use the ground terminal on the generator to
ground the generator.
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.
Mounting
The generator should always be mounted on a flat level
surface to isolate vibration of the generator when it is
running. DO NOT place the generator on slopes, the
possibility exists that the generator could slide.
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 3) 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 a minimum of 8 ft. into the ground.
MQ GA-2.9R A.C. GENERATOR — OPERATION & PARTS MANUAL — REV. #0 (10/28/04) — PAGE 19
MQ GA-2.9R — INSTALLATION
Connecting the Ground
The nut and ground terminal on the generator should always be used to connect the generator to a suitable ground. 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 5) and tighten the
nut fully. Connect the other end of the ground cable to a suitable earth ground (ground rod).

General Inspection Prior to Operation
Ground Power Tools
When using power tools or electrical equipment requireing AC
power from the generator, make sure connecting (power tool)
cable (Figure 6) has a ground as shown in Figure.
Extension Cable
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 3) as a guide for selecting proper cable size.
