Interconnection

Before interconnecting system components to the SITRANS LU01 terminals, verify all
components have been installed in accordance with the associated product instruction
manuals.
Connect all associated equipment cable shields to the SITRANS LU01 shield connections.
To avoid differential ground potentials, do not connect cable shields to ground (earth)
elsewhere. Insulate or tape cable shields at all shield junctions to prevent ground loops.
