How to connect transmitters in potentially explosive areas

General principles in relation to connecting and using Exd transmitters should be
consistent with the rules and standards concerning equipment with flame-proof housing as
in point 7.1, including:
EN60079-14 - Electrical equipment in potentially explosive atmospheres. Part 14:
Electrical installation in risk areas (other than mines).
EN60079-17 - Electrical equipment in potentially explosive atmospheres. Part 17:
Inspection and operation of electrical installation in hazardous areas (other than mines).
Cables should be protected against damage by laying them in cable trays, lining
pipes, cable ladders, using durable fastenings etc.
Transmitters and equipment in a transmitter measurement loop should be
connected in accordance with explosion-proof standards and conditions of use in
hazardous areas.
Failure to comply with explosion-proof may result in an explosion and risk to
humans associated with it.
Transmitters should be powered by power supplies or other equipment that
ensures that there is reinforced insulation between primary and secondary
windings and which do not exceed 250V AC. It is the user who is responsible for
the provision of power supply in compliance with the aforementioned
requirements.
