IEC Conditions of Certification (general):
• The ambient temperature range is limited to –50°C to +60°C for the Ex d e [ib] IIC T5, Ex d e IIC T5 version, and
–55°C to +60°C for the Ex d [ib] IIC T5, Ex d IIC T5 version.
• Only suitable certified Ex d or Ex e (as applicable) cable entries and blanking elements are to be used.
• The Model OPECL assemblies are to be installed in places where there is a low risk of mechanical damage.
• The field wiring terminal connections are certified for a single wire in size from 0.2 to 2.5 mm
2 , (or two conductors
with same cross section 0.2 to 0.75 mm 2 ). The screws must be tightened down with a torque 0.4 to 0.5 Nm.
• The metal housing of the Model OPECL Gas Detector must be electrically connected to earth ground.
