SECTION 3
European Union Installations (ATEX 2014/34/EU Directive)
II (1) G [Ex ia Ga] IIC
II 3 (1) G Ex nA [ia Ga] IIC T4 Gc
When installed in non-hazardous locations:
The STZ shall be mounted within a tool-secured enclosure capable of accepting the applicable wiring
methods specified in EN 60079-14. The enclosure shall, at a minimum, meet the requirements of IP20.
When installed as Category 3 equipment and/or in Zone 2 locations
:
The STZ shall be mounted within a tool-secured enclosure which meets the requirements of EN 60079-0
and EN 60079-15 and is capable of accepting the applicable wiring methods specified in EN 60079-14.
The enclosure shall, at a minimum, meet the requirements of IP54.
The non-metallic parts incorporated in the STZ DIN mount housing may generate an ignition-capable
level of electrostatic charge. The STZ shall not be installed in a location where the external conditions are
conducive to the build-up of electrostatic charge on such surfaces. Additionally, the equipment shall only
be cleaned with a damp cloth.
The STZ shall be provided with supply transient protection external to the apparatus such that the
voltage at the supply terminals does not exceed 119Vac peak or 119Vdc
