The generator/engine set is inherently a self regulating
unit based on engine speed. The engine governor will
automatically adjust itself to the load. No harm to the
generator will result if it is operated with no load con-
nected. Proper utilization of the receptacles located on
the control panel is necessary to prevent damage to
either the receptacles or the generator.
The generator is a limited source of electrical power,
therefore pay special attention to the receptacle and
generator ratings. The nameplate rating can be ob-
tained through a single receptacle as long as the recep-
tacle amperage rating is not exceeded.
GROUNDING THE UNIT
All units must be grounded. Drive a 3/4 or 1” copper
pipe or rod into the ground close to the generator/
engine set. The pipe must penetrate moist earth. Con-
nect an approved ground clamp, to the pipe. Run a no.
10 AW wire from clamp to the generator ground lug on
the receptacle panel. Do not connect to a water pipe or
to a ground used by a radio system.
The generator/engine set covered in this manual is d
signed for portable use. DO NOT OPERATE THIS
GENERATOR INDOORS. During a power outage,
move the unit outdoors to a flat dry location such as a
driveway or sidewalk before use. The unit should be
stored in a warm dry location.
WIRING
Plug your tools such as drills, saws, blowers, sump
pump and other items to be powered directly into the
generator receptacles. Before plugging in all the tools
and cord sets, recheck the rating of the generator set.
Be sure it can handle the intended load and is compati-
ble with the voltage, phase, and current ratings.
‘Hard Wiring’ this unit directly into a temporary construc-
tion site electrical system is NOT A SIMPLE DO-IT-
YOURSELF JOB. For your safety all wiring must be
done by a qualified electrician and conform to the Na-
tional Electric Code and comply with all state and local
codes and regulations. Check with local authorities be-
fore proceeding.
WARNING: PERSONAL DANGER
A fully isolated, double pole double thro manual
transfer s itch must be installed any time a generator
is being connected to an existing distribution system.
1. These engine generator sets are designed for port-
able heavy duty commercial use. Receptacles are
provided on the control panel to permit 120 and 240
volt portable appliances and tools to be plugged
directly into them. Please note that the 3-wire 240
volt receptacle-(s) on these units are designed to
power only 240 volt tools. There are two hot leads
and a ground wire, but no neutral connection, in the
3-wire 240 volt receptacle.
A 4-wire receptacle (two hot, one ground, and one neu-
tral) has been provided on the control panel for use in
temporary power applications requiring 120/240 volt
power. Consult a licensed electrician for wiring the
‘Tempower Plug’, and connecting it as temporary ser-
vice. To connect these units directly to an un-powered,
isolated construction site ‘Tempower Panel’, have your
electrician connect to the control panel using a 120/240
volt, 4-wire twist-lock plug (L14-30P). The use of locking
receptacles and locking plugs provides the convenience
of quick disconnect, for moving, while allowing workers
to safely reconnect the power. In addition they prevent
the plug from being accidentally removed by bumping or
vibration.
2. If the generator set is be connected to existing distri-
bution system a fully isolated manual transfer switch
must be installed. The transfer switch prevents dam-
age to the generator and other circuit components if
main line power is restored while the generator is
connected. Installing a transfer switch also permits
the use of normal fusing.
3. Many homes and construction sites are wired for at
least 60 to 100 Amp entrance service, much greater
than the capacity of these portable generators. When
installing the generator at these sites, a secondary
emergency distribution panel may have to be in-
stalled, such as the Emergency Transfer/Service
(ET/S) system available through Hy-Tech. The emer-
gency distribution panel must be installed by a li-
censed electrician according to all applicable codes.
The electrician will move the critical circuits to be
powered during the outage to the emergency panel.
Keep in mind only a limited amount of amperage is
available from the generator set. Some circuit break-
ers may still have to be turned off to prevent an over-
load on the generator during the initial start up. See
the nameplate on your generator for the amperage
capabilities of your unit.
CAUTION: EQUIPMENT DAMAGE
Failure to properly limit and balance the load applied to
the generator ill cause the generator to produce lo
voltage and may damage the engine generator set. It
may also cause severe damage to the loads connected
to the generator at that time. Improper loading of the
generator set constitutes abuse and ill not be covered
by arranty.
ENGINE CARE
If major engine service or repair is required contact an
authorized engine service center. The manufacturer of
these engines has established an excellent world-wide
engine service organization. Engine service is very like-
ly available from a nearby authorized dealer or distribu-
tor. Check the yellow pages of your local telephone di-
rectory under “Engines- asoline” for the closest engine
repair center or ask the dealer from whom you pur-
chased the power plant.
