5. Connecting the conductor end
Several possibilities of how to connect
HVI
light Conductors
to the air-termination system/roof parapet
will be described below.
In the connection area, an adjustment area must be observed around the
HVI
light Conductor
(Figs. 5a
to 5d). No electrical, conductive or earthed parts may be located in this area to ensure that lightning currents
are safely conducted into the conductor.
Case 1
In this case, connection to the equipotential bonding system is not required. A spacer with an insulating
clearance of 910 mm (Part No. 106 812) is installed at a distance of 1200 mm (measured from the connection
element).
The adjustment area shown in Fig. 5a must be maintained.
The equivalent separation distance is s ≤ 45 cm (in air).

GRP length = 1000 mm, plastic bushing,
plastic conductor holder (Ø 20 mm)
- Concrete base e.g. Part No. 102 340
- FB roof conductor holder, Part No. 253 015
