IDENTIFICATION RECORD

DATA PLATE

Every generator has a DATA PLATE which contains
important information pertinent to the generator. The
data plate lists the unit's serial number, its rated volt-
age, amps, wattage capacity, phase, frequency, rpm,
power factor, etc.
Generator Model Number: This number is the key to
numerous engineering and manufacturing details per-
taining to your unit. Always supply this number when
requesting service, ordering parts, or seeking informa-
tion.
Voltage Code X: The GR Series generators are capable
of supplying a variety of single-phase and 3-phase volt-
ages, in total referred to as an X voltage code. They
include the following:
• 120/208 to 139/240 volts, single phase, 60 Hz.
• 120/208 to 139/240 volts, 3-phase, 60 Hz.
• 240/416 to 277/480 volts, 3-phase, 60 Hz.
The above voltage ratings are stated in the form,
V ph /V L .
— V ph is the phase voltage (i.e., voltage above
neutral).
— V L is the line-to-line voltage.

EQUIPMENT DESCRIPTION

This equipment is a revolving field, alternating current
generator set. The generator is designed to supply elec-
trical power for the operation of compatible, electrical
loads when Utility Power is unavailable.
The generator's revolving field is directly connected to
and driven by an engine by means of flexible discs and
a coupling assembly. Units with 4-pole rotors are driv-
en at speeds of 1800 rpm to supply a rated frequency of
60 Hz.
Trailerized models are mounted on highway trans-
portable trailers equipped with breakaway safety chains
and a jockey wheel. Weather-resistant, all-metal, sound-
attenuated enclosures protect the units against the ele-
ments while substantially reducing noise.

STANDARD GENERATOR FEATURES

This generator incorporates the following features:
• The unit meets temperature rise standards for
Class "F" insulation
MG1-22.40, NEMA MG1-1.65 and NEMA MG1-1-
66.
• The generator is self-ventilated and drip-proof con-
structed.

Note:
as defined by
• The voltage waveform deviation, total harmonic
content of the AC waveform and "telephone influ-
ence factor" have been evaluated and are acceptable
according to NEMA MG1-22.
• A state of the art magnetic circuit provides minimal
level of waveform distortion and an electro-magnet-
ic interference level which meets accepted require-
ments for standard AM radio, TV and marine radio
telephone applications.
