Case 2
As is the case with case 1, no equipotential bonding connection element is required and thus the
HVI
light
Conductor
is not connected to the equipotential bonding system. A spacer with an insulating clearance of
41 cm (Part No. 106 852) is installed at a distance of 120 cm (measured from the connection element). The
adjustment area shown in Fig. 5b must be maintained.
The equivalent separation distance is „s“ ≤ 30 cm (in air).
