Installing Hvi ® Power Conductors - DEHN + SÖHNE HVI power Montageanleitung

The following must be observed:
The black surface of the HVI
Â
tial bonding connection element (Part No. 410 329).
The surface must be smooth and free of grease.
Â
Possible grease must be removed using a cloth soaked with a special cleaning agent (Part No. 297
Â
199).
The equipotential bonding connection element must not be soiled.
Â
The screw of the equipotential bonding connection element must be tightened with a tightening
Â
torque of 10 Nm.
The equipotential bonding connection element has to firmly enclose the HVI

6.3 Installing HVI
The entire HVI power Conductor has to be installed in the protected zone of the air-termination
®
system of the external lightning protection system and must not contact parts of the air-termination
system, down conductor or structural parts that carry lightning voltage. An exception can be made if
the separation distance "s" at the point where the HVI
lightning voltage (air-termination system, capping of the roof parapet, down conductor) is ≤ 35 cm (in
air) or ≤ 70 cm (in case of solid material). In this case, the sheath of the HVI
be connected to the part carrying lightning voltage.
If installed downstream of the sealing end range, the HVI
vals of ≤ 1 m. The fixing screws of the metal conductor holders must be tightened with a tightening
torque of max. 5 Nm.
If the HVI power Conductor is installed in a structure, protection measures, e.g. fire barriers, have
®
to be taken.
