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