• Close unused cable openings for electrical connections.

• Check the cables for a tight fit after installation.

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
