Installing the isCon system
5 7 5 Creating additional equipotential bonding in potentially explosive
areas
The following information explains the creation of the equipotential bond-
ing of installations in potentially explosive areas. See also „4.4 Installation
in potentially explosive areas“ on page 24.
In Ex zones 1 and 21, connect the isCon cable to the equipotential bond-
ing at regular intervals (≤ 0.5 metres). To do this, bring the black cable
jacket into contact with metallic cable brackets, e.g. isCon H VA or PAE.
Routing on earthed, metallic building structures
For routing along an earthed, metallic building structure (e.g. electrically-
conductive connected metal facades, steel structures or mesh structures):
• Use the metallic isCon H VA cable bracket to fasten the cable to the
building structure.
• Connect the metallic building structure with the equipotential bonding
or with the earthing system.
