Figure Example of the Conguration in Hazardous Area
When the NI-compliant equipment is connected, energy exchange between them may a󰀨ect
the properties of NI-compliant equipment. Therefore, to ensure the properties, it is necessary to
compare parameters among connected equipment in advance. With the results, it is necessary to
determine whether general wiring can be used for connection in a hazardous area or dedicated
explosion-proof wiring is needed. To compare parameters, it is required to display parameters on
NI-compliant equipment.
