Installation
Two-wire control generator types: These generator types
integrate the control circuits for start-up, running, and stopping
(Figure 2-13). The generator starts and runs when two control wires
are connected, and then stops when they are disconnected.
Three-wire momentary control generator types: These
generator types use a 3-position momentary type switch that
controls their operation (Figures 2-14 & 2-16). To start the generator,
the switch is momentarily held in the START position. This energizes
the ignition system and cranks the starter motor. Once the engine
has started, the switch is released and returns to a center position
(i.e., “momentary” run control). To shut down the generator, hold
the switch in the STOP position until the engine dies. Once released,
it returns to the center position (i.e., “momentary” stop control).
Three-wire maintain control generator types: These generator
types use an automotive type starting circuit (Figure 2-15). To start
the generator, turn the operating switch to a RUN position and then
momentarily hold it in the START position. Once the engine starts,
release the switch and it returns to the RUN position (i.e., “maintain”
run control). To shut down the generator, move the switch to the
OFF position (i.e., “maintain” stop control).
2.7 Warning
Label
It is unsafe to perform maintenance on the generator/electrical panel
if just the generator is turned off. The AGS system can automatically
turn on the generator and power the panel. See Figure 2-12.
The supplied warning label informs all that an automatic generator
starting device is installed in your electrical system. Place the label
in a clearly visible location at the generator (ensure it is visible
at the generator cabinet or at the enclosure that guards against
electrical shock or moving parts hazards).
WARNING: To protect servicing personnel, ensure the
generator and AGS are properly disabled (i.e., remove starting
battery from generator and remove all power to the AGS by
unplugging the AGS’s terminal block) prior to performing
maintenance on the generator or electrical panel.

WARNING
ELECTRICAL SHOCK HAZARD
PN: 62-0002 Rev B
This electrical system is equipped with an Automatic Generator
Starting (AGS) device and/or an inverter. Disconnect all AC and
DC power to the AGS and/or inverter before performing any
service to the electrical system. Failure to do so can result in
shock causing serious injury or death.
