Note 1. For best results, OMRON recommends using only shielded, twisted-pair
cable. Shields should be connected in a star fashion to the shield terminal.
2. Shield terminals are not directly connected to chassis ground of the Rack.
They are used as a floating reference for the isolated analog ground plane in
the Unit.
