30 Xanbus Automatic Generator Start (AGS) Owner’s Guide
Xanbus Automatic Generator Start Installation
Connecting an External Shutdown (optional)
The external shutdown input is a 12-volt/24-volt input used to assure that
the AGS keeps the generator off under conditions that may be potentially
hazardous. Wire 5 (white/black) and 6 (gray) on the wiring harness are
intended for an external switch or sensor (such as a moisture detector, or
carbon monoxide detector) that produces an active high 12-volt or 24-volt
output.
Connecting an External Manual ON/OFF
Switch (optional)
The external manual ON/OFF inputs (wires 7 and 8 on the wiring harness)
are intended for wiring to one or more remote ON/OFF switches for starting
and stopping the generator manually. Wire 7 (Start) and wire 8 (Stop)
should each run to their own momentary-contact switch or push-button. The
other contact on both switches (common) should be connected to wire 11 on
the harness.
In order for the Xanbus Automatic Generator Start (AGS) to be able to
detect these switches, connect the fused positive of the generator battery to
wire 10 on the harness (the constant 12-volt/24-volt wire). See Figure 23 on
page 32. Ensure all circuits added to the system comply with “Circuit
Limitations” on page 11.
If the generator battery does not have the required voltage, any 12-volt or
24-volt power source meeting the limits on page 11, will suit this purpose.
If an alternate power source is used, its positive terminal must be connected
to wire 10. Its negative must be connected to wire 11.

NOTE: Internally, wire 11 is connected to wire 13 so it may already be
connected to the negative terminal on the generator battery.
NOTE: Internally, wire 11 is connected to wire 13, so in this
configuration, the alternative power source negative may already be
connected to the negative terminal on the generator battery.
FIRE AND ELECTRICAL SHOCK HAZARD
When making connections to a 12-volt or 24-volt power source that
exceeds the class 2 power limitation of 100 VA (e.g., a battery) always
use over-current protection as defined in Table 2. This also applies to
thermostat and external manual ON/OFF connections. Locate the
protection device at the power source in the positive wire.
Do not connect the AGS to a 48-volt battery bank. The AGS is limited to
a 30V open-circuit maximum by its regulatory approval and cannot be
connected to a 48-volt power source.
Failure to follow these instructions can result in death or serious
injury.
