Capacitive, inductive, and lamp loads must be operated with protective circuitry.When used with HD1KO / HD2KO ● The display contains plastic parts - do not open in an explosiveatmosphere.Adjustment In the event of a required adjustment of the switching value, the switching head can beadjusted via a longitudinal adjustment. Upon reaching the switching value, the switchingunit is fixed using a fastening screw.Order information The basic device (e.g. HD1K-015GM005A) is ordered plus switching head ATEX A-H4.2.Art. no.489133 489134 489135Order designationATEX A-H4.1-489133ATEX A-H4.1-489134ATEX A-H4.2-489135Version with cable, length 2.5 m with cable, length 5 m device connectordsh_fam_atex_a-h4_en_vs01.odt 1
