Conext Automatic Generator Start Installation

Installing the Xantrex XW Automatic Generator Start
975-0307-01-01 2–25
Connecting an External Shutdown (optional)
The external shutdown input is a 12-volt/24-volt input used to assure that
the Xantrex XW 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 Xantrex XW Automatic Generator Start 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 2-23 on page 2–27. Ensure all circuits added to the system
comply with Table 2-2, “Circuit Limitations” on page 2–5.
If the generator battery does not have the required voltage, any 12-volt or
24-volt power source meeting the limits on page 2–5, 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.
