Bleed Down Box Instructions Wiring the MN-Bleeder. The MN-Bleeder goes inline between the array(s) and the inverter acting as a pass-through. There are two rows of box lugs at the bottom of the circuit board. Each connection in the front row is directly tied to the connector behind it in the back row. Connect PV1 + from the array to the connector marked PV1 + and run a suitable wire from the other PV1 + connector to the Inverter PV+ input. Connect PV2+ (if used) in a similar fashion.
