Fig 57: Minimum required distance between the connection element and the
potential connection terminal in air
Legend for Fig 57:
1 Clip distance (x) from the potential connection terminal to the con-
nection element in centimetres
2 Calculated separation distance (s) in centimetres
A isCon BA 45 SW
B isCon Pro+ 75 SW/GR and isCon Pro 75 SW
C isCon PR 90 SW
Example:
If the calculated separation distance is 60 cm, then you can use the
variants isCon Pro, Pro+ or Premium. Install the potential connection
terminal 120 cm in front of the connection element.
Note!
I f the calculated separation distance is less than the appropriate tested
equivalent separation distance in air, you can reduce the distance be-
tween the potential connection terminal and the connection element (x)
accordingly.
If the calculated separation distance
Pro+, Premium) and 20 centimetres (Basic), then no additional potential
connection is required in front of the rear connection element.
Note!
T he conductor type isCon BA 45 SW (Basic) can be routed with or with-
out potential connection. If the conductor is routed without a potential con-
nection, observe "Mounting variant 2 for isCon BA 45 SW" on page 54.
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 Fig. 56). These include, for
example, metallic construction parts, conductor brackets and assem-
blies.
– Connect the potential connection terminal to the equipotential bonding
with ≥ 6 mm² Cu or a material with identical conductivity (see Fig. 58).
