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 three-wire generator has fewer automated functions than a
two-wire. 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 RELAY AUX terminals cannot provide.
The 12V AUX terminals may be used to operate the conversion kit, as shown in Figure 23 .
If the AUX terminals are being used for another purpose, it may be necessary for the RELAY AUX
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.
