WARNING
Risk of electric shock!
If there is a lightning strike in the lightning protection system, lethal volt-
ages can occur in the lightning protection system.
Do not work on the lightning protection system during a thunderstorm or
if there is the risk of one, and do not install interception masts in the im-
mediate vicinity of high-voltage cables.
5 1 Cutting and removing the insulation of the isCon cable
The isCon cable is sold by the metre and in two variants:
– As a black isCon cable isCon 750 SW
– As a light grey isCon cable isCon 750 LGR with additional external
protective jacket.
The light grey isCon cable is suitable for routing in the earth. It can also
be painted, e.g. with the paint of the facade. As the external light grey pro-
tective jacket is non-conductive, it must be removed in the contact areas.
• Shorten the isCon cable on site to the required length using standard
cable cutters or saw.
5 1 1 Removing the light grey protective jacket (isCon 750 LGR)
In the case of the isCon 750 LGR cable, before attaching elements for
potential connection, remove the light grey jacket in the contact area, so
that the connection comes into contact with the black, weakly-conductive
material.
ATTENTION
Risk of damage!
The black jacket may not be removed, as otherwise the connection to the
building's equipotential bonding can be interrupted. Observe the cutting
depth of the grey cable jacket of 1.5 mm.
When mounting isCon connect or isCon IN connect:
• Remove 50 mm of the grey cable jacket with a cable knife.
