EX requirements
It is required that:
● Electrical
connections are in accordance with Elex V (VO in explosion hazardous areas) and
EN60079-14 (Installing Electrical Systems in Explosion Hazardous Areas).
● The protective cover over the power supply is properly installed. For intrinsically safe circuits
the connection area can be opened.
● Appropriate cable connectors are used for the output cicuits: intrinsically safe: blue, non-
intrinsically safe: black.
● Sensor and transmitter are connected to the potential equalization. For intrinsically safe
output circuits potential equalization must be maintained along the entire connection path.
● Sensor insulation thickness is max. 100mm (only insulated sensors).
● EN60079-31 is considered for installation in areas with combustible dust.
● When protective earth (PE) is connected, no potential difference between the protective
earth (PE) and the potential equalization (PA) can exist, even during a fault condition.
