・
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 IECEx certified intrinsically safe type
in case it is used on the intrinsically safe circuit in the hazardous area or of
a IECEx certified non-incendive type in case it is used in the non-incendive circuit
in the hazardous area.
