Item Question
Rating
YES
NO
1
Is the whole system positioned in the protected area?
2
Has the separation distance been calculated?
(down conductor to the earth-termination system, isolated system with connection to existing
external lightning protection system or lightning equipotential bonding on roof level)
3
Is the maximum equivalent separation distance specified by DEHN for the application
of the
HVI
Conductor kept?
HVI
light Conductor / DEHNcon H
s ≤ 0.45 m in air
s ≤ 0.9 m solid material
HVI
Conductor
s ≤ 0.75 m in air
s ≤ 1.5 m solid material
HVI
power Conductor
s ≤ 0.9 m in air
s ≤ 1.8 m solid material
4
Is the calculated separation distance kept in the range of the sealing end?
5
Is the supporting tube and, if required, the equipotential bonding element of the sealing end
correct, i.e. only connected with the equipotential bonding / the lightning equipotential bond
-
ing of the system?
6
Is the minimum distance of 0.2 m kept between HVI
Conductors routed in parallel and has the
connection to opposite down conductors been considered?
7
Has the minimum bending radius been kept?
HVI
light Conductor (dark grey outer coating)
200 mm
HVI
Conductor (black outer coating)
200 mm
HVI
Conductor (grey outer coating)
230 mm
HVI
power Conductor (black outer coating)
270 mm
8
Is the equipotential bonding element of the sealing end in contact with the semiconductive
layer (not grey coating)?
9
Has the supplementary information in DEHN installation instructions No. 1501/No.1892
