Handling and operation
Note
All
●For use only in intrinsically safe power circuits - Provide a suitable isolating amplifier.
●Cable lengths max. 5 m.
●It must be ensured that the values given for voltage, current, and power are not exceeded.
●When switched on, a load must be connected in series.
●The electrical details apply to ohmic loads. Capacitive, inductive and lamp loads must be operated using a protective circuit.

HD1KO- / HD2KO-
●Display with plastic parts - do not open in an explosive atmosphere.
