5.1 Basic safety notes
Unprotected cable ends
Risk of explosion through unprotected cable ends in hazardous areas.
• Protect unused cable ends in accordance with IEC/EN 60079-14.
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.
Note
Electromagnetic compatibility (EMC)
For metal housings there is an increased electromagnetic compatibility compared to high-
frequency radiation. This protection can be increased by grounding the housing, see
Connecting SITRANS LR200 (Page 35).
