2.2 Installation in hazardous location
WARNING
Equipment used in hazardous areas must be Ex-approved and marked accordingly. It is
required that the special conditions for safe use provided in the manual and in the Ex
certificate are followed!
Ex approvals
CSA Class I, Division 2, Groups A, B, C and D. Code T5 for an ambient temperature of
+60ºC.
FM Class I, Division 2, Groups A, B, C and D and Class I, Zone 2, Group IIC indoor/outdoor
Type IP67 hazardous (classified) locations

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).
● EN50281-1-2 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.
