Standards:
EN IEC 60079-0: 2018, EN 60079-11: 2012
Markings:
[HART]: II 1 G Ex ia IIC T6…T4 Ga
[Fieldbus/PROFIBUS]: II 1 G Ex ia IIC T4 Ga
See Table 5-5 for entity parameters and temperature classifications.
Special Conditions for Safe Use (X):
1. The equipment must be installed in an enclosure which affords
it a degree of protection of at least IP20 in accordance with the
requirements of IEC 60529. Non-metallic enclosures must have
a surface resistance of less than 1 GΩ; light alloy or zirconium
enclosures must be protected from impact and friction when
installed in a Zone 0 environment.
2. When fitted with the Transient Protector Assembly, the
equipment is not capable of withstanding the 500 V test as
defined in Clause 6.3.13 of EN 60079-11:2012. This must be
taken into account during installation.
