WARNING
Lack of equipotential bonding
Danger of explosion through compensating currents or ignition currents through lack of equipotential bonding.
● Ensure that the device is potentially equalized.
Exception: It may be permissible to omit connection of the equipotential bonding for devices with type of protection
"Intrinsic safety Ex i".
WARNING
Unprotected cable ends
Danger of explosion through unprotected cable ends in hazardous areas.
● Protect unused cable ends in accordance with IEC/EN 60079-14.
WARNING
Loss of degree of protection
When connecting the SITRANS TS100 or TS200 with type protection "Intrinsically safe", ensure the following:

● Use IP54 rated enclosure
WARNING
Lemo plug in hazardous areas
For Lemo plug version (7MC7xxx-xxxx2-xxx) make sure the cable ends are in an environment free from dust, water, or
shock
WARNING
Improper laying of shielded cables
Danger of explosion through compensating currents between hazardous area and the non-hazardous area.
● Only ground shielded cables that run into the hazardous area at one end.
● If grounding is required at both ends, use an equipotential bonding conductor.
WARNING
Connecting device in energized state
Danger of explosion in hazardous areas.
● Connect devices in hazardous areas only in a de-energized state.
Exceptions:
● Circuits of limited energy may also be connected in the energized state in hazardous areas.
● Exceptions for type of protection "Non-sparking nA" (Zone 2) are regulated in the relevant certificate
Note
Electromagnetic compatibility (EMC)
You can use this device in industrial environments, households and small businesses.
For metal housings there is an increased electromagnetic compatibility compared to high-frequency radiation. This
protection can be increased by grounding the housing, see Chapter "Electrical connection (Page 17)".
