GDP-5000H — GENERAL INFORMATION
WARNING:
Before connecting this generator to any
building’s electrical system, a licensed
electrician must install an isolation
(transfer) switch.
Serious injury or death may result without
this transfer switch.
GDP-5000H FAMILIARIZATION
Generator
The Multiquip Model GDP-5000H generator has been
designed as a portable dual purpose power source for 60
Hz (single phase) lighting facilities, power tools, submersible
pumps and other industrial and construction machinery. In
addition the Model GDP-5000H has been designed as a
power source for 180 Hz, 3-phase concrete vibrators.
This generator is powered by a HONDA 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
box
. To reduce vibration caused by the engine, the control
box is also placed on rubber isolators.
control
Excitation System
The GDP-5000H-series generators use a magnet attached
to a flywheel to produce AC voltage from a lamp coil beneath
the flywheel. As the magnetic 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.
Engine
The four-cycle air-cooled HONDA gasoline engine is designed
to meet every performance requirement of this generator.
Reference Table 1, page 8 for engine specifications
Figure 1 (page 11) shows the basic controls and indicators
for the GDP-5000H generator.
Control Box
The control box is provided with the following:
z
Three 240V output receptacles (three phase).
z
One 120V output output receptacle (single phase).
z
One 120/240V output output receptacle (single phase).

PAGE 10 — GDP-5000H A.C. GENERATOR— OPERATION AND PARTS MANUAL — REV. #2 (07/23/08)
GDP-5000H — INSTALLATION
Outdoor Installation
Install the generator in a location where it will not be exposed to
rain or sunshine. Make sure that 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, not only to the engine
parts, but also to the alternator parts.
CAUTION :
Pay close attention to ventilation when
operating the generator inside confined
areas. The engine exhaust contains
noxious elements.
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.
CAUTION :
Preventing electrical shock. Pay close
attention to handling when operating
concrete vibrators. Always use rubber
boots and gloves to insulate the body from
a short circuit.

GDP-5000H — LOAD APPLICATION
Single Phase Load — 60 Hz
CAUTION:
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.
NOTE
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
To determine the running wattage for your load, multiply the
running wattage as indicated by steps 1, 2, and 3 below:
An inadequate size connecting cable which cannot carry
the required load can cause a voltage drop which can burn
out the appliance or tool and overheat the cable.
The idle control is operated at minimum load capacity of
100W. If the load capacity is less than 100W, throw the idle
control switch to the OFF position.
CAUTION:
Three Phase Load — 180 Hz
Motors and motor-driven equipment draw
much greater current for starting than
during operation.
Before connecting this generator to any
building’s electrical system, a licensed
electrician must install an isolation
(transfer) switch. Serious injury or death
may result without this transfer switch.

box. When the voltmeter indicates 120 volts, 120 volts from
the 120V receptacles and 240 volts from the 240V receptacle
can be obtained at the same time. Refer to Figure 1, Controls
and Indicators, item 7 on page 10.
DO NOT change the engine speed control
lever which has been set at the factory prior
to shipping.
3.Close the choke. Adjust the opening of the choke valve
according to operating conditions. When the engine is
warm or the air temperature is high, close the choke
valve halfway or open it all the way.
4.Confirm that both main circuit breakers (60 and 180 Hz)
on the generator control box are in the “OFF” position.
5.Set the operation switch to the “ON” position and grasp
the starting knob and slowly pull it out. The resistance
becomes hardest at a certain position, corresponding
to the compression point. Rewind the rope a little from
that point and pull out sharply.
6.If the engine fails to start, repeat the procedure.

GDP-5000H — MAINTENANCE
General Inspection
At least daily or prior to each use, the generating set should
be cleaned and inspected for deficiencies. Check for loose,
missing or damaged nuts, bolts or other fasteners. Also check
for fuel or oil leaks.
Engine Side (Refer to the Engine Instruction Manual)
Check Oil Level
Check the crankcase oil level prior to each use, or when the
fuel tank is filled. Make sure the generating set is level. The
oil level must be between the two notches on the dipstick.
Changing Oil
Change oil after the first 20 hours of operation. Drain and
refill the engine crankcase every 50 operating hours or once
a week thereafter. Drain crankcase oil into a suitable container
while engine is still warm. Replace the drain plug tightly. Add
oil through the filler hole.
Air Cleaner
Every 50 hours: Remove air cleaner element (std. or heavy
duty types), and wash in kerosene or liquid detergent and
hot water. Wrap foam element in a cloth and squeeze dry.Wipe
heavy duty paper element dry with toweling. Saturate element
with kerosene; squeeze excess from foam element. Wipe
excess from heavy duty paper element.
Service Daily
If engine is operating in very dusty and dry grass conditions.
A clogged air cleaner will result in high fuel consumption,
loss of power and excessive carbon build-up in the
combustion chamber.
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.
Spark Plug
Remove carbon build-up on the spark plug (Figure 5) with a
wire brush. Set the spark plug gap to 0.6—0.7 mm (0.024-
0.028 inch). Tighten with a spark plug socket wrench. Clean
the spark plug every 50 operating hours or once a week.
