IDENTIFICATION RECORD
DATA LABEL
Every generator set has a DATA LABEL that contains important
information pertinent to the generator (Figure 1.1). The data label,
which can be found attached to the generator’s lower connection
box, lists the unit’s serial number and its rated voltage, amps, watt-
age capacity, phase, frequency, rpm, power factor, etc.
Figure 1.1 — Data Label
NOTE:
The above is a generic representation of a data label. For actual
information related to this particular model, please refer to the
“construction document” located at the end of this manual, or
to the data labels affixed to the unit.
Identification Code (Type Code)
Use this code to obtain important information about the generator.
For example, if the code is ...
SD 0100 A G17 4.5 D 18 H B Y Y 3
– identify the generator as follows:
• SD – Stationary emergency diesel generator (“SG” indicates a
stationary emergency gaseous fuel unit).
• 0100 – Rated output is 100,000 watts (100 kW).
• A – Voltage code (see “Voltage Codes”).
• G17 – Indicates engine MFG.
• 4.5 – Engine is 4.5 liter.
• D – Unit has diesel fuel system (“N” indicates natural gas;
“L” indicates LP Liquid Withdrawal; “V” indicates LP Vapor
Withdrawal).
• 18 – Engine rpm rating (15 = 1500 rpm (50Hz units), 18 =
1,800 rpm, 23 = 2.300 rpm, etc.) Note that engines operating
at a speed higher than 1800 RPM utilize a gearbox to reduce
the engine RPM to the desired alternator rotor RPM of 1800 for
60 Hz operation.
• H – Unit has an option “H” control panel ("G" panels are also
available on some units).
• B – Indicates a brushless excitation unit (“P” indicates a perma-
nent magnet excitation).
• Y – Unit is equipped with a standard enclosure (“N” indicates
no enclosure; “S” indicates Level 1 sound attenuation; "L" indi-
cates Level 2 sound attenuation).
• “Y” indicates a muffler has been mounted; N – Unit does not
have an exhaust muffler; “L” indicates a muffler has been
shipped loose with the unit).
• 3 – Emission designation (for factory use).
Groups and Assembly Numbers
The XPL label lists the groups and corresponding assembly num-
bers for each unit. The assembly numbers refer to exploded view
drawing numbers that are applicable to the specific generator
model.
Voltage Codes
The identification code letter following the unit’s kilowatt rating is
the generator’s “voltage code.” Any one of the following voltage
codes may be listed.
A – 120/240 volts, single-phase, four-lead, 60 Hz
D – 120/240 volts, single- and three-phase, 12-lead, 60 Hz
G – 120/208 volts, three-phase, 12-lead, 60 Hz Broad Range
J – 120/240 volts, three-phase, 12-lead, 60 Hz Broad Range
K – 277/480 volts, three-phase, 12-lead, 60 Hz Broad Range
L – 346/600 volts, three-phase, six-lead, 60 Hz
M – 110/220 volts, single-phase, four-lead, 50 Hz
N – 115/200 volts, three-phase, 12-lead, 50 Hz Broad Range
P – 100/200 volts, three-phase, 12-lead, 50 Hz Broad Range
R – 231/400 volts, three-phase, 12-lead, 50 Hz Broad Range
S – 277/480 volts, three-phase, six-lead, 50 Hz
All units are configured at the factory for a specific voltage output
(code) and cannot be field converted to a different voltage code
(this will void the UL label on the unit).
GENERATOR SET XPL LABEL
Every generator set has a XPL LABEL affixed to the lower con-
nection box (Figure 1.2). Additionally, a printed CONSTRUCTION
DOCUMENT containing identical information can be found at the
end of this manual.
When requesting information, ordering replacement parts, asking
for service, etc., one or more of the following may be needed:
• Generator Model Number/Generator Serial Number
• Date of Manufacture
• Generator Type Code
• Generator Assembly Groups
