Creating additional equipotential bonding for isCon Pro+ in
potentially explosive areas
The following information explains the creation of the equipotential bond-
ing of installations in potentially explosive areas. See also "6.4 Installa-
tion in potentially explosive areas" on page 27.
In Ex zones 1 and 21, connect the isCon
bonding at regular intervals (≤ 0.5 metres). To do this, bring the protect-
ive jacket into contact with metallic conductor holders, 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 struc-
tures):
• Use the metallic conductor holder to fasten the conductor to the build-
ing structure.
• Connect the metallic building structure with the equipotential bonding
or with the earthing system.
