External transfer switch connection

If an external transfer switch is used, connect its auxiliary relay to the screw connector terminals on the control panel's backside. When the auxiliary relay is open, the AC current limit can be adjusted by the control panel knob. If the auxiliary relay is closed, the control panel sends a preset generator AC current limit to the inverter/charger system. The auxiliary relay is controlled by the external transfer switch.
