A
UX
terminals
5
and
6
are the
A
UX
output – and + terminals. These terminals are colored gray (–) and
orange (+) for easy reference. The terminals can supply up to 250 mA at 12 Vdc (3 W). This circuit
contains electronic overcurrent protection, which resets after being overloaded. No additional fuses are
required for
A
UX
terminals.
The
A
UX
indicator illuminates when the output becomes active. (See page 30
for a description of the LED
indicators and their functions.)

AUX Diversion Control
In this example, the
A
UX
output directly drives a 12-volt vent fan. The – and + wires on the fan are connected to
A
UX
terminals
5
and
6
, the
A
UX
– and
A
UX
+ terminals
.
In this example, the
A
UX
drives a relay that diverts wind power. The relay’s coil is connected to
A
UX
terminals
5
and
6
, the
A
UX
– and
A
UX
+ terminals
.
When the
A
UX
output closes the relay (based on battery voltage), the relay diverts excess power to
a water heating element.
