IECEx – Certification Scheme for Explosive Atmospheres
For BRS devices labeled with an IECEx certificate number, the following
applies:
List of standards:
IEC 60079-0:2017
IEC 60079-7:2017
IEC 60079-15:2017
Make sure that the device has the following label:
Ex ec nC IIC T4 Gc IECEx: DEK 20.0079 X
T4: 0 °C ≤ Ta ≤ +60 °C (+32 °F ≤ Ta ≤ +140 °F) for device types “S“
or “C“
(Position 16 of the product code) or
T4: -40 °C ≤ Ta ≤ +70 °C (-40 °F ≤ Ta ≤ +158 °F) for device types
“T“, “E“ or “G”
(Position 16 of the product code)
The equipment is suitable for use in an area with maximum pollution
degree 2, as defined in IEC 60664-1.
The modules shall be installed in a suitable enclosure in accordance
with IEC 60079-0 providing a degree of protection of at least IP54
according to IEC 60529, taking into account the environmental
conditions under which the equipment will be used.
When the temperature under rated conditions exceeds +70 °C
(+158 °F) at the cable or the conduit entry point, or +80 °C (+176 °F)
at the branching point of the conductors, take measures so that the
temperature specification of the selected cable and cable entries is in
compliance with the actual measured temperature values.
Connectors shall be connected or disconnected exclusively in dead-
voltage state.
Bei ACA22-USB-C (EEC)When using ACA22-USB-C (EEC) on
the USB interface, verify that the ACA22-USB-C (EEC) is
mechanically secured with the fastening screw. ACA22-USB-C
(EEC) Exclusively connect or disconnect the ACA22-USB-C
(EEC) when it is voltage-free. In hazardous areas, exclusively
operate the ACA22-USB-C (EEC) on the USB interface.
