WARNING
Lack of equipotential bonding
Risk 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
Risk 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:
• Adhere to the requirements for electrical connection seperation.
• 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
Risk of explosion through compensating currents between hazardous area and the
non‑hazardous area.
• Shielded cables that cross into hazardous areas should be grounded only at one end.
• If grounding is required at both ends, use an equipotential bonding conductor.
