Notes for use in hazardous locations according to ATEX, IECEx, UKEX and CCC Ex
If you use the device under ATEX, IECEx, UKEX or CCC Ex conditions you must also keep to
the following safety instructions in addition to the general safety instructions for protection
against explosion:
Transient overvoltages
Take measures to prevent transient overvoltages of more than 40% of the rated voltage (or
more than 119 V). This is the case if you only operate devices with SELV (safety extra-low
voltage).
Suitable cables at high ambient temperatures in hazardous area
At an ambient temperature of ≥ 60 °C, use heat-resistant cables designed for an ambient
temperature at least 20 °C higher. The cable entries used on the enclosure must comply with
the IP degree of protection required by EN IEC / IEC 60079-0, GB 3836.1.
Safety notices when using the device according to Hazardous Locations (HazLoc)
If you use the device under HazLoc conditions you must also keep to the following safety
notices in addition to the general safety notices for protection against explosion:
EXPLOSION HAZARD
You may only connect or disconnect cables carrying electricity when the power supply is
switched off or when the device is in an area without inflammable gas concentrations.
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).
