6.1 Safety when connecting up
Lack of equipotential bonding
If there is no equipotential bonding in hazardous areas, there is a risk of explosion due
to equalizing current or ignition sparks.
• Ensure that equipotential bonding is available for the device.
Unprotected cable ends
There is a risk of explosion due to unprotected cable ends in hazardous areas.
• Protect unused cable ends according to IEC/EN 60079-14.
Improper installation of shielded cables
There is a risk of explosion due to equalizing currents between the hazardous area and
the non-hazardous area.
• Ground shielded cables that cross hazardous areas at one end only.
• Lay a potential equalization conductor when grounding at both ends.
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 the
• Observe the device approvals applicable for your country.
