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.
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.
The “two-wire” generator types (Figure 2-9) integrate the control
circuits for start-up, running and stopping. The generator starts and
runs when two “control” wires are connected, and stops when they
are disconnected.
The “three-wire momentary” generator types (Figures 2-10 & 2-12)
use a three-position momentary type switch that controls their
operation. To start the generator, the switch is momentarily held to
the
START
position. This energizes the ignition system and cranks
the starter motor. Once the engine has started, the
START
switch is
released and it returns to a center position (i.e., “momentary” run
control). To shut down the generator, the switch is held to the
STOP
position until the engine dies. Once the switch is released, it returns
to the center position (i.e., “momentary” stop control).
The “three-wire maintain” generator types (Figure 2-11) use an
automotive type starting circuit. Operating a switch that is
fi
rst
turned to a
RUN
position and then momentarily held to a
START
position to start the generator. Once the engine has started, the
switch is released and it returns to the
RUN
position (i.e., “maintain”
run control). To shut down the generator, the switch is moved to the
OFF
position (i.e., “maintain” stop control).
