Safety Instructions - dehn HVI Installation Instructions Manual

Installation,
electrotechnical expertise
HVI Conductors may only be installed under the conditions shown and referred to in these instal-
Â
lation instructions.
Only qualified and trained personnel (lightning protection specialists) may install HVI Conductors.
Â
We recommend to visit a special training course on HVI products held by DEHN.
For safety reasons, installation work must be stopped as soon as a thunderstorm approaches/is
Â
noticed.
The components of the HVI system have been tested as a complete system. Mixing compo-
nents of the HVI system with components from other manufacturers is not permitted.
Prior to installation, HVI Conductors must be examined for good order and condition. If damage or
Â
any other defect is found, the HVI Conductor must not be installed. The black sheath of HVI Con-
ductor must not be damaged by compressive deformation or cuts.
When using HVI Conductors in potentially explosive atmospheres, fire and explosion protection
Â
measures must be taken.
If HVI Conductors are installed on thatched roofs (e.g. reed, straw), special installation conditions
Â
must be observed for these flammable locations. These special installation conditions for HVI Con-
ductors are described in our Lightning Protection/Earthing main catalogue (HVI Lightning Protecti-
on for Thatched Roofs).
If the supporting tube is led through a roof, the roof must be properly sealed. Warm roofs must be
Â
properly sealed and insulated.
HVI Conductors are suitable for outdoor use and can be installed downstream of the sealing end
Â
e.g. on roofs, in walls, under plaster, in concrete or on facades/facade constructions. Only HVI Con-
ductors with an additional grey sheath may be installed in the soil, e.g. to connect the down con-
ductor installed on the building to the ring earth electrode over a length of max. 2 m. HVI Conduc-
tors must not be used to locally increase the potential gradient area in the soil (risk of step voltage).
Soiled HVI Conductors can be cleaned with a cloth soaked with a special cleaning agent (Part No.
Â
297 199). To be able to comply with dangerous goods regulations, this product is only transported
within Germany and Austria. ISOPROPYL ALCOHOL (99.1 to 99.9 %) (CSA No. 67-63.0) can be used
as an alternative!
