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. 4, page 11).

The following steps must be observed:

Screw the locking screw of the head piece (M8 x 25 mm) to the head of the supporting tube.

Insert the HVI

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

tor 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,

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

installation can be verified by slightly pulling the conductor at the point where the conductor leaves

the supporting tube.

Depending on the construction of the installation, the relevant air-termination tip/air-termination

rod must be installed before or after the supporting tube has been installed.

Insert the air-termination tip/air-termination rod from above into the head of the supporting tube

and tighten the two locking screws (M8 x 16 mm/M8 x 10 mm) using a tightening torque of 15 Nm.
