Installation; Installing Hvi ® Power Conductors In The Supporting Tube - DEHN + SÖHNE HVI power Montageanleitung

6. Installation

6.1 Installing HVI
Before installing the supporting tube, insert and fix the head piece of the pre-assembled HVI
Conductor into the supporting tube (see also Fig. 5, page 19).
The following steps must be observed:
Unscrew the locking screw of the head piece (M8 x 25 mm) at the head of the supporting tube.
Â
Insert the HVI power Conductor from below into the supporting tube. To this end, the compressive
®
Â
strength of the integrated equipotential bonding spring element must be overcome. The conductor
can be inserted and removed several times. To contact the head piece, insert the HVI
ductor into the supporting tube as far as it will go and hold it there.
The locking screw (M8 x 25 mm) is firmly tightened again using a tightening torque of 15 Nm. Thus,
Â
the head piece is fixed in the supporting tube and is electrically connected (capable of carrying light-
ning currents). Make sure that there is a sufficient distance (about 7 mm) between the screw head is
and the supporting tube after tightening the locking screw. The adhesive coating of the screw only
hardens after about 5 minutes so that the screw can be correctly positioned and tightened during
this period. After hardening of the adhesive coating, the screw must be replaced by a new one if the
screw is removed.
Check whether the HVI
Â
Proper installation can be verified by slightly pulling the conductor at the point where the conductor
leaves the supporting tube.
Depending on the design of the installation, the relevant air-termination tip or air-termination rod
Â
must be installed before or after the supporting tube has been installed.
Insert the air-termination tip or air-termination rod from above into the head of the supporting tube
Â
and tighten the two locking screws (M8 x 16 mm / M8 x 10 mm) using a tightening torque of 15 Nm.
