Connection element
Potential connection with e.
• Equipotential bonding (connection mm²) not ne-
cessary for separation distance 0.15 m
• Throughout both connection areas, the respective
calculated separation distance (s) the metal
parts must maintained. cable mm²

: Potential connection
• The potential control element should connected
to reference potential using mm² an
equivalent conductivity. the calculated separation distance
(s) less than the equivalent separation distance of
the appropriate isCon®
conductor, then the distance
between the potential connection clip and the connec-
tion element (x) can reduced accordingly. These include, for example,
metallic construction parts and cable brackets well
as assemblies.
No electrically conductive earthed parts may be
located the area between the connection element
and the potential connection the radius the calcu-
lated separation distance.
• Lightning current must not flow through the refer-
ence potential and must the protective
angle the lightning protection system.
• This means that the potential connection can be
made via local equipotential busbar, metallic and
earthed roof structures, earthed parts the build-
ing structure and via the protective conductor the
low-voltage system.
