Two-Wire-Start (12V AUX Terminals)
The 12 Vdc signal provided by the 12V AUX terminals can be switched on and off to provide a start
signal. It is not usually recommended to connect the AUX terminals directly to the generator, but to
use the 12V AUX terminals to energize the coil of a 12 Vdc automotive or similar relay.
Depicted is the OutBack FLEXware Relay Assembly, which is sold for this purpose. The relay contacts
can serve in place of the generator’s start switch. The battery shown below is depicted for clarity. In
most cases, it is part of the generator’s internal starting circuit and is not an external component.
The drawing below is one example of a possible arrangement. Specific arrangements, relays, and
other elements depend on the requirements of the installation and of the generator.
