Two-Wire Start (12V AUX Terminals)
The 12 Vdc signal provided by the
12V
A
UX
terminals can be switched on and off to provide a start
signal. It is not usually recommended to connect the
A
UX
terminals directly to the generator, but to
use the
12V
A
UX
terminals to energize the coil of a 12 Vdc automotive or similar relay.
The OutBack FLEXware Relay Assembly depicted in Figure 24 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 the battery 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.
