Control Wiring Terminal Block:
The Inverter ON/OFF terminals are used for
connecting an external ON/OFF switch. To
use this feature, the jumper must be removed.
(See installation manual for details.)
The AUX terminals provide a 12 Vdc signal.
The AUX terminals can be used to start a
generator or to control external devices.
AUX terminals are also available in the charge
controller and FLEXnet DC. See the charge
controller or FNDC manuals for details.
CAUTION: Equipment Damage
When connecting cables from the inverter to the battery
terminals, ensure the proper polarity is observed.
Connecting the cables incorrectly can damage or destroy
the equipment and void the product warranty.
