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
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.
•
WARNING
Insufficient isolation of intrinsically safe and non-intrinsically safe circuits
Risk of explosion in hazardous areas.
When connecting intrinsically safe and non-intrinsically safe circuits ensure that isolation is carried out properly in
•
accordance with local regulations for example IEC 60079-14.
Ensure that you observe the device approvals applicable in your country.
•
WARNING
Connecting device in energized state
Risk of explosion in hazardous areas.
Connect devices in hazardous areas only in a de-energized state.
•
Exceptions:
Devices having the type of protection "Intrinsic safety Ex i" may also be connected in 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 Technical data (Page 21).
