6.6.2 IA ATEX FISCO Intrinsic Safety
Certificate Baseefa09ATEX0093X
Standards EN IEC 60079-0:2018, EN 60079-11:2012
Markings
Special Conditions for Safe Use (X):
1. The equipment must be installed in an enclosure that provides a
degree of protection of at least IP20. Non-metallic enclosures must
be suitable to prevent electrostatic hazards and light alloy or
zirconium enclosures must be protected from impact and friction
when installed.
2. The equipment is not capable of withstanding the 500 V insulation
test required by EN 60079-11:2011, clause 6.3.13. This must be
taken into account when installing the equipment.
