・ Barriers and power supply specification must not exceed the maximum values as
shown in the diagram above. These safety descriptions cover most of the commonly
used industry standard barriers, isolators and power supplies.
・ The Hand Held Communicator must be of a ATEX certified intrinsically safe type in
case it is used on the intrinsically safe circuit in the hazardous area or of a ATEX
certified non-incendive type in case it is used in the non-incendive circuit in the
hazardous area.
