Connecting the Generator
To connect the XW Automatic Generator Start to a generator, you must identify the start
wiring configuration of the generator you want to use. Generators must be auto-start
capable, and generators equipped with remote operation connections are ideal.
If the generator is equipped for remote operation, you must examine the wiring of the
remote cable and connector (or read your generator’s documentation, if available) and
identify the following wires:
• Ground
• Start
• Stop
• Generator run signal, also known as the Hour Meter or Switched B+ (battery positive)
Wiring
requirements To wire the XW Automatic Generator Start to the generator, you need #16 or #18 AWG
wire connected between contacts 12 to 20 on the wiring harness. How many of these wires
you connect and in which combination depends on your generator type.
Generator types The XW Automatic Generator Start has 13 preset generator configurations, or “Gen
Types” (see the XW Automatic Start Owner’s Guide for details on Generator Types). To
ensure that the XW Automatic Generator Start is compatible with your generator’s
starting circuitry, you must select your type of generator from the XW Automatic
Generator Start menu on the XW System Control Panel after completing the installation.
