Three-Wire Start
A “three-wire-start” generator has two or more starting circuits. It usually has a separate switch or
position for cranking the generator. A generator with three-wire start has fewer automated functions
than a two-wire-start generator. It usually requires multiple controls for starting, running, or
stopping. The inverter terminals cannot control this type of generator without using a three-wire to
two-wire conversion kit.
Atkinson Electronics
(http://atkinsonelectronics.com)
is one company that makes these kits. The
Atkinson GSCM-Mini is intended to work with OutBack inverters.
NOTE:
The conversion kit requires a 12-volt signal which the
R
ELAY
A
UX
terminals cannot
provide. The
12V
A
UX
terminals may be used to operate the conversion kit as shown in Figure 25 .
If the
A
UX
terminals are being used for another purpose, it may be necessary for the
R
ELAY
A
UX
terminals to control an external relay and 12-volt source in conjunction with the conversion kit. The
wiring and requirements for this arrangement will depend on the circumstances.
