Installing the isCon system
Legend for Figure 57:
1
Clip distance (x) from the potential connection terminal to the con-
nection element in centimetres
2
Calculated separation distance (s) in centimetres
If the calculated separation distance is 0.75 metres, then install the poten-
tial connection terminal 1.5 metres in front of the connection element.
Note! If the calculated separation distance is less 0.75 metres in air, then you
can reduce the distance between the potential connection terminal and
the connection element (x) accordingly.
If the calculated separation distance
2
is less than 15 centimetres, then
no additional potential connection is required in front of the rear connec-
tion element.
In addition, observe the following when connecting the equipotential
bonding:
– Do not locate any electrically-conductive or earthed parts within the
calculated separation distance s in the area between the potential con-
nection and the connection element (see Figure 56). These include,
for example, metallic construction parts, cable brackets and assem-
blies.
– Connect the potential connection terminal to the equipotential bonding
with ≥ 6 mm² Cu or a material with identical conductivity (see Figure
58).

≥ 6 mm²

tion terminal
With metallic, earthed substrates, use the metallic cable bracket isCon H
VA. When screwed directly to the substrate, it also provides equipotential
bonding.
Note! When using the light grey isCon isCon 750 LGR cable, the light grey
protective jacket must be removed in the area of the cable bracket (see
„5.1.1 Removing the light grey protective jacket (isCon 750 LGR)“ on
page 29).
