Routing the isCon
®
conductor
When routing the isCon
®
conductor to the forwarding conductor system,
observe the following information:
– The complete isCon
®
conductor must be located in the protection area
of the lightning protection system.
– The black conductors may not be routed in the earth. They may not be
painted. Instead, use the grey isCon Pro+ 75 GR conductor.
– Only use the accessories for fastening (see section 3.4.3 on page
18).
– The isCon
®
conductor may only be connected onward using the OBO
connection elements of the appropriate isCon
®
variant.
– An isCon
®
conductor may not be extended.
– When making route changes, maintain the minimum bend radius (see
Tab. 2 on page 10).
– Route the isCon
®
conductor in such a way that it cannot be damaged
by sharp-edged objects.
– If the isCon
®
conductor is damaged, the entire section must be re-
placed, as otherwise the correct function cannot be guaranteed. This
does not apply to the isCon
®
conductors Pro+ 75. The Pro+ 75 vari-
ants may exhibit any damage to the grey external jacket and/or protec-
tive jacket, if they are not used as protection against touch voltages.
However, the protective jacket must also be continuously present,
even in cases of damage, and have a thickness of 0.2 mm. The black,
weakly conductive layer may not be damaged or interrupted.
– Ensure that the conductor is connected to the equipotential bonding
of the structure as described in section 6.6. Create additional
equipotential bonding for metallic objects which cross or run in parallel
(see section 6.6.4 on page 55).
– Special measures must be complied with for routing in potentially
explosive areas (see “4.4 Installation in potentially explosive areas” on
page 25).
– No point of the protective jacket or black, weakly conductive layer of
the isCon
®
conductor may come into contact with parts carrying light-
ning current.
– Elements fastening the isCon
®
conductor may be spaced a maximum
of 1 metre apart.
