2.0 Installation
2.7 Warning Label
It might be falsely assumed that it is safe to perform maintenance on the
generator or the electrical panel once the generator is off. However, the AGS
system can automatically turn on the generator and power the panel.
A warning label (Figure 2-12) is provided to inform all personnel 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
especially visible at the generator cabinet or at the enclosure that guards
electrical shock or moving parts hazards).
WARNING: To prevent harm to servicing personnel, e nsure the gen-
erator and AGS are properly disabled (i.e., remove the starting battery
from the generator, and remove all power to the AGS by u nplugging
the green 8-port terminal block from the AGS module ) prior to per-
forming maintenance on the generator or electrical panel.

WARNING
This electrical system is equipped with an Automatic
Generator Starting device and/or an inverter. Disconnect
all AC and DC power to the ME-AGS-N and/or inverter
before performing any service to the electrical system.
Failure to do so can result in shock causing serious injury
or death.

2.6 Common Generator Wiring Diagrams
The most common generator starting/run/stop circuits can be divided into
three major types – 2-wire control, 3-wire momentary control, or 3-wire
maintain control. The following gen wiring diagrams are provided as examples:
Info: The term “3-wire” refers to the minimum number of wires
required to control the starter motor and to run the generator; more
than three wires may actually be needed.
Two-wire control generator types: These generator types integrate the
control circuits for start-up, running, and stopping (Figure 2-13). The gen-
erator 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 three-position momentary type switch that controls their operation
(Figure 2-14). 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 it returns to a
center position (i.e., “momentary” run control). To shut down the generator,
the switch is held in the STOP position until the engine dies. Once the switch
is 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, an
operating switch is fi rst turned to a RUN position and then momentarily held to
a START position. Once the engine starts, the switch is released and it returns
to the RUN position (i.e., “maintain” run control). To shut down the genera-
tor, the switch is moved to the OFF position (i.e., “maintain” stop control).
