Notes.
Parameters apply to entire system inclusive of cables.
Each specified electrical parameter must be applied individually and in combination. Do not
exceed the maximum values when applying the electrical parameters individually or in
combination.
Both Intrinsic safety and dust ratings are combined when APA592-pH.A1… is ordered.
