Prior to installing an ON/OFF switch, if the FX’s AC output is off, check that the jumper is
present and well-connected before installing a switch. You want to confirm the system is
in good working order.
Should you decide to install an OutBack MATE at a later date, bear in mind the installed
switch overrides the control provided by the MATE if the switch is set to OFF. If the switch
is set to ON, the MATE will function normally and control the inverter(s).
AUXILIARY OUTPUT ( AUX + / AUX - )
The Auxiliary output system uses the AUX + and AUX – terminals. It is programmed through the MATE
to do a variety of tasks:
• The default use for these terminals drives the OutBack FX Turbo Kit or DC12-FAN accessory for
external cooling.
Note: These terminals should not be connected to any type of DC load greater than 0.7 amps.
• The FX includes internal electronic over-current protection for the AUX 12 Vdc output circuit which
auto resets if it is short-circuited. No additional fuses are required.
• For automatic or advanced generator start functions, the Auxiliary Output can drive a 12 Vdc
automotive relay for the two-wire starting circuitry of a generator. OutBack recommends a good
quality gold-plated relay.
Note:
(1) The FLEXnet DC comes with an internal relay for this use.
(2) OutBack Power Systems does not support three-wire start generators; however, a three-wire to
two-wire conversion kit is available from an electronic control manufacturer such as Atkinson
Electronics (www.atkinsonelectronics.com)
(3) Either the MATE or the FLEXnet DC can be programmed for Auto-Gen Start (please refer to
component manuals for more information).
