IEC 60417-6182:
Installation,
electrotechnical expertise
HVI power Conductors may only be installed in Ex zones 1/21 under the conditions shown and
®
Â
referred to in these installation instructions.
Only qualified and trained personnel (lightning protection specialists) is allowed to install
Â
HVI power Conductors. We recommend to visit a special training course on HVI
®
by DEHN + SÖHNE.
These installation instructions on the special use of the HVI
Â
are a supplement to installation instructions No. 1892 (HVI
screws, the conductor holders are fitted with adhesive-coated screws. These M6 screws must be
tightened using a tightening torque of 5 Nm. Typically, black HVI
holder unit can be rotated by 90° by loosening the centre screw (M8) and must be tightened again
using a tightening torque of 10 Nm.
The isolated air-termination system including the air-termination tip and sealing end of the
Â
HVI power Conductor can be positioned in Ex zone 2/22.
®
No deposits must be present in the space between the HVI
Â
surface (roof or wall). This can be achieved by cleaning the installation surface or sufficiently eleva-
ting the HVI power Conductor.
®
The HVI power Conductor features a conductive plastic sheath. If it is likely that special gases or
®
Â
substances attack (destroy) the sheath material, the HVI
Within Ex zones, consequent equipotential bonding must be provided. External conductive systems,
Â
e.g. electrical cables, pipe systems, cable racks, etc. must be connected with the semi-conductive
sheath of the HVI
Alternatively, separation distance s according to DIN EN 62305-3 (VDE 0185-305-3), Lightning Pro-
tection Part 3, Section 6.3, has to be kept.
If the required separation distance from these external conductive systems cannot be kept,
Â
HVI power Conductor has to be connected to the equipotential bonding in distances according to
®
intallation variants.
Modification of the components is not permitted. Prior to installation, it must be ensured that no
Â
potentially explosive atmosphere is present at the work location!
