Requirements regarding cabling in hazardous areas
The cables must fulfill the requirements set forth in IEC 60079-14.
Cables that are subject to exceptional thermal, mechanical, or chemical loads must be
specially protected (e.g. laid in open-ended conduits).
Cables that are not installed as fire proof must be flame retardant according to
IEC 60332-1.
Ferrules must be attached to the wire ends to ensure that they do not split up.
The applicable requirements regarding air gaps and creepage distances must be
observed in accordance with IEC 60079-11. The available air gaps and creepage dis-
tances in the terminal box must not be reduced when connecting the cables.
The equipotential bonding must be in accordance with IEC 60079-14.
The SPU housing must be connected to the potential equalizer. In intrinsically safe cir-
cuits, provide equipotential bonding along the wiring runs of the current outputs.
The applicable national regulations shall also be observed.
NOTICE:
Special requirements for installation in hazardous zones in mines are of first
importance and must be observed.
