The interface between the panel mount receptacles and associated increased safety enclosure to which they may be
fitted cannot be defined. Therefore it is the user’s responsibility to ensure that the appropriate ingress protection level
of the associated enclosure is maintained at this point.
•
When marked with the code Ex op pr IIC T6 Gb or Ex op pr IIC T6 Gb, the connectors are only to be installed within
an Ex d IIC GB rated enclosure, suitable for the assigned ambient temperatures.
•
When marked with the code Ex op pr IIC T6 Gb or Ex op pr IIC T6 Gb, any fibre optic cable must be protected in
accordance with the relevant code of practice.
