Safety notices for use according to ATEX and IECEx
If you use the device under ATEX or IECEx conditions you must also keep to the following
safety notices in addition to the general safety notices for protection against explosion:
WARNING
Take measures to prevent transient voltage surges of more than 40% of the rated voltage.
This is the case if you only operate devices with SELV (safety extra-low voltage).
WARNING
Provisions shall be made to prevent the rated voltage from being exceeded by transient
disturbances of more than 119 V.
WARNING
Safety notice for connecting with a LAN ID (Local Area Network)
A LAN or LAN segment with all the interconnected devices should be contained completely in
a single low voltage power distribution in a building. The LAN is designed either for
“Environment A” according to IEEE802.3 or "Environment 0" according to IEC TR 62102.
Do not connect any electrical connectors directly to the telephone network (telephone network
voltage) or a WAN (Wide Area Network).
Safety notices when using the device according to ATEX/IECEx and FM
If you use the device under ATEX/IECEx or FM conditions, you must also observe the following
safety notices in addition to the general safety notices for protection against explosion:
WARNING
Do not remove or replace while circuit is live when a flammable or combustible atmosphere is
present.

Note
Strain relief for the Ethernet cables
In order to avoid mechanical stress on the Ethernet cables and resulting interruption of the
contact, fasten the cables at a short distance from the connector using a cable guide or busbar.
