Note: Shelf addressing, current share and RS485 communications are all referenced to the most negative

power output Vout(-) of the shelf. For paralleled shelves the Vout(-) terminations must be tied together in order

to ensure proper operation of these functions. Modules could get damaged if this connection is not made. .
