GENERATOR AC LEAD CONNECTIONS
See “Voltage Codes”. This Stationary Emergency
Generator may be rated at any one of five voltages,
either single-phase or three-phase. The electrical
wires in the unit’s AC connection (lower) panel should
be installed according to the number of leads and the
voltage/phase required for the application. If there
are any questions regarding lead connection, refer to
the wiring diagrams at the back of this manual.
Voltage codes apply to the type of stator assembly
installed on a particular generator.
ALTERNATOR POWER WINDING
CONNECTIONS
FOUR-LEAD, SINGLE-PHASE STATOR
Four-lead generators are built to supply electrical
loads with voltage code "A" (240V, 1-phase, 60Hz).
Electrical power is produced in the stator power
windings. These windings were connected at the fac-
tory to the main circuit breaker as shown in Figure
7.1.
The rated voltage between each circuit breaker ter-
minal is 240V. The rated voltage between each circuit
breaker terminal and the neutral point 00 is 120V.
Figure 7.1 — Four-lead, Single-phase Stator
3-PHASE ALTERNATORS ("Y" CONFIGURATION)
The Stationary Emergency Generator is designed
to supply 3-phase electrical loads. Electric power is
produced in the alternator power windings. These
windings were connected at the factory to the main
circuit breaker with a “Y” configuration as shown in
Figures 7.2, 7.3, and 7.4.
The rated voltage between circuit breaker terminals
E1-E2, E1-E3 and E2-E3 is either 480V or 208V
depending on the model.
The rated voltage between each circuit breaker termi-
nal and the neutral point 00 is either 277V or 120V
depending on the model.

Stationary Emergency Generator
General Information
ACConn005 Rev. A 09/08
STATIONARY EMERGENCY GENERATOR
CONTROL AND OPERATION
Refer to the appropriate control panel operator’s
manual for this unit.
OPERATING UNIT WITH MANUAL
TRANSFER SWITCH
If the Stationary Emergency Generator was installed
in conjunction with a transfer switch capable of man-
ual operation only, the following procedure applies.
A manually operated transfer switch is one that will
not provide automatic start-up and does not include
an intelligence circuit.
ENGINE START-UP AND TRANSFER
For additional information, refer to the applicable
control panel manual for this unit, as well as any lit-
erature pertaining to the specific transfer switch.
DANGER
The Maintenance Disconnect Switch and the
AUTO/OFF/MANUAL switches (if so equipped)
must be set properly, or the generator will crank
and start as soon as the utility power to the
transfer switch is turned off. Refer to applicable
control panel and transfer switch manuals for
more information.
Do not proceed until certain that utility source
voltage is available to the transfer switch and
the transfer switch main contacts are set to
UTILITY.
Do not attempt manual operation until all power
supplies to the transfer switch have been posi-
tively turned off, or extremely dangerous - pos-
sibly lethal - electrical shock will result.
Transfer switch enclosure doors should be kept
closed and locked. Only authorized personnel
should be allowed access to the transfer switch
interior. Extremely high and dangerous voltages
are present in the transfer switch.
In order to transfer load from the utility source to the
generator, follow these directions:
• Turn OFF or disconnect the utility power circuit
to the transfer switch, using the means provided
(such as the utility source main line circuit break-
er).
• Set the transfer handle to its UTILITY (NORMAL)
position with load circuits connected to the utility
power supply.
• Set the generator’s main line circuit breaker to its
OFF (or OPEN) position.
• Start the generator.
Do not crank the engine continuously for longer
than 30 seconds, or the heat may
damage the starter motor.
• Let engine stabilize and warm up.
• Check all applicable instrument and gauge read-
ings. When certain that all readings are correct,
move the transfer switch manual handle to the
STANDBY position, i.e., load circuits supplied by
the generator.
• Set the generator’s main line circuit breaker to its
ON (or CLOSED) position.
• Load circuits are now powered by the generator.
RETRANSFER AND SHUTDOWN
For additional information, refer to the applicable
control panel manual for this unit, as well as any lit-
erature pertaining to the specific transfer switch.
To transfer the load back to the utility power source
and shut down the generator, follow these direc-
tions:
• Set the generator’s main line circuit breaker to its
OFF (or OPEN) position.
• Manually move the transfer switch handle to its
UTILITY (NORMAL) position, i.e., load circuits
connected to the utility.
• Turn ON the utility power supply to the transfer
switch, using the means provided (such as the util-
ity power source main line circuit breaker).
• Let the generator run at no-load for a few minutes
to stabilize internal temperatures.
• Shut down the generator.
OPERATING UNIT WITH AUTOMATIC
TRANSFER SWITCH
If the Stationary Emergency Generator has been
installed with an automatic transfer switch, such
as an RTS, HTS, or GTS-type transfer switch, the
engine may be started and stopped automatically or
manually.
NOTE:
Refer to the applicable manual for your trans-
fer switch and to “Transfer Switch Start Signal
Connections”. In addition, please note the dangers
under “Engine Start-up and Transfer.”
