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 generator was installed in conjunction with a transfer switch
capable of manual 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 literature pertaining to the
transfer switch.
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 infor-
mation.
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 positively turned off, or extremely dan-
gerous — possibly 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 trans-
fer 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 breaker).
• Set the transfer handle to its UTILITY (NORMAL) position with
load circuits connected to the utility power supply.
• Set the Stationary Emergency Generator's main line circuit
breaker to its OFF (or OPEN) position.
• Start the generator.
Do not crank the engine continuously for lon-

ger than 30 seconds, or the heat may dam-
age the starter motor.
• Let engine stabilize and warm up.
• Check all applicable instrument and gauge readings. When
certain that all readings are correct, move the transfer switch
manual handle to its STANDBY position, i.e., load circuits sup-
plied by the generator.
• Set the Stationary Emergency Generator's main line circuit
breaker to its ON (or CLOSED) position.
• Load circuits are now powered by the Stationary Emergency
Generator.
RE-TRANSFER AND SHUTDOWN
For additional information, refer to the applicable control panel
manual for this unit, as well as any literature pertaining to the
transfer switch.
To transfer the load back to the utility power source and shut down
the generator, follow these directions:
• Set the Stationary Emergency Generator's main line circuit
breaker to its OFF (or OPEN) position.
• Manually move the transfer switch handle to its UTILITY (NOR-
MAL) 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 utility 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 generator has been installed along with an automatic transfer
switch, such as a GTS-type switch, the engine may be started and
stopped automatically or manually.
Refer to the applicable manual for the transfer switch and to
"Transfer Switch Start Signal Connections". In addition, please
note the dangers under "Engine Start-up and Transfer."
