The engine will govern itself at full speed. Intentionally overriding
the governor and operating the generator at low voltage may
damage both the generator and any load connected to it.
Running the engine at excessively high speeds results in high
voltage, which may significantly shorten the life of light bulbs and
appliances being used, as well as possibly damaging the engine.
Output voltage should be checked periodically to ensure
continued proper operation of the generating plant and
appliances. If the generator is not equipped with a voltmeter, it
can be checked with a portable meter. Frequency can be
checked by using an electric clock with a sweep second hand.
Timed against a wrist watch or a stop watch the clock should be
correct within +/- 2 seconds.
CONNECTING THE LOADS
Applying The Load - Allow the engine to warm up for two or three
minutes before applying any load. This will allow the engine to
reach normal operating temperature and oil to circulate
throughout the engine. A short warm-up time will permit the
engine to work more efficiently when the load is applied and will
reduce the wear in the engine, extending its life.
1. The generator output is provided at the junction box on top of
the generator shell. Receptacles may have been provided by the
vehicle manufacturer for convenient load connection. The loads
should be applied gradually. When starting large electric
motor(s), they should be started individually when possible. The
largest motor should always be started first.
CAUTION: EQUIPMENT OVERLOAD
Keep the generator load within the generator and receptacle
nameplate rating. Overloading may cause damage to the
generator and/or the loads
a. Most electric tools and devices will have the voltage and
amperage requirements on their individual nameplates.
When in doubt consult the manufacturer or a local electrician.
The nameplate amperage rating for electric motors can be
misleading. See “Starting Electric Motors” in Specification
Section.
b. These engine generator sets are inherently self regulat-
ing 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 connected.
c. Proper utilization of the generator output power is
necessary to prevent damage to either the tools or the
generator. The generator is a limited source of electrical
power, therefore pay special attention to the generator
ratings. The nameplate rating can be obtained through a
combination of all four generator leads or a single lead pair
as long as the current capacity of the generator windings are
not exceeded. Both the 120 and 240 volt capabilities can be
utilized at the same time if so wired. See Specification
Section for proper load separation.
WIRING
These engine generator sets are designed for mobile vehicular
use. The generator output consists of two independent 120 volt
windings. These windings may be connected in series to permit
120 and 240 dual voltage availability, or in parallel to provide 120
volt only power at higher amperage.
Please note that any standard 3 wire 240 volt receptacle provided
by the vehicle manufacturer is designed to power only 240 volt
tools. There are two hot and one ground wire.... but no neutral
connection in the 3 wire 240 volt receptacle. Split 120/240 volt
TemPower service on an extension cord requires the installation
of a 4 wire receptacle (2 hot, 1 ground, and 1 neutral). Consult a
licensed electrician for wiring a TemPower plug and splitting the
cord output into 120 and 240 volt power service.
To connect this unit directly to an un-powered, isolated mobile
vehicle distribution panel, have your electrician wire the generator
to the load(s) using one of the following methods:
1. Connect the generator output to a distribution panel using a
fine strand (flexible) motor lead wire. Install a mainline circuit
breaker at the panel to protect the generator output winding and
distribution wiring. The required breaker rating will depend upon
the voltage desired. Use a single pole 20 or 25 Amp breaker for
the 120/240 volt (series) connection. Use a 40 or 45 Amp single
pole breaker for the 120 volt only (parallel) connection.
2. Wire the generator output to a 120/240 volt, four wire
twistlock receptacle. (NEMA L14-30 {30 Amp} or Hubbell Spec.
#CS 6365 {50 Amp}) The use of locking receptacles and locking
plugs provides the convenience of quickly disconnecting the
wiring for applications requiring the unit to be moved or for and
security. The plug also allows non electrical workers to safely
reconnect the power after moving the unit and prevents the plug
from being accidentally removed by bumping or vibration.
CAUTION: EQUIPMENT DAMAGE
Failure to properly protect and limit the load applied to the
generator will cause the generator to produce low voltage and
may damage the engine generator set. With the 120/240 volt
connection, the 120 volt loads must be balanced to prevent
overloading either of the two generator windings. It may also
cause severe damage to the loads connected to the generator at
that time due to low voltage. Improper loading of the generator
set constitutes abuse and will not be covered by warranty.
INSTALLING A REMOTE KEY SWITCH
This engine generator set comes equipped with a terminal block
wire for the installation of a remote key switch. Any universal key
switch may be used as long as it is a three position switch
(STOP, ACC and START). Below is a diagram of the terminal
block that is provided on the unit on the bottom of the existing key
switch.
