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
Insu󹪟cient 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
Incorrect conduit system
Risk of explosion in hazardous areas as result of open cable inlet or incorrect conduit system.
• In the case of a conduit system, mount a spark barrier at a de󹪝ned distance from the device
input. Observe national regulations and the requirements stated in the relevant approvals.
WARNING
Connecting or disconnecting device in energized state
Risk of explosion in hazardous areas.
• Connect or disconnect devices in hazardous areas only in a de-energized state.
• Install a suitable switch-o󹪜 device.
Exceptions:
• Devices having the type of protection "Intrinsic safety Ex i" may also be connected in
energized state in hazardous areas.
WARNING
Energized devices
Risk of electric shock or explosion.
When energized the device may be opened by quali󹪝ed personnel only.
