4.4 Certificates and approvals
4.4.1 Ex approval
The stainless steel version of the CYA112 assembly (CYA112-**21*2**) may also be used
in the hazardous area in Zone 1 and 2.
It does not have special Ex identification labeling, as the assembly does not have a
potential ignition source of its own and ATEX Directive 2014/34/EU therefore does not
apply.
If sensors have accessible metal surfaces, these sensors must be included in the potential
equalization system as indicated in the Operating Instructions for the sensor in question.
