The arc sensor can be mounted from the outside on partition wall of the switchgear. The active
part of the sensor is mounted in a 10mm hole, to the area in the switchgear that should be
protected, and fastened with a 4mm self-tapping screw.

The arc sensor can alternatively be mounted completely in the protected area with the help of a
Z-shaped or L-shaped mounting plate. In open spaces, such as the bus bar section, arc sensors
should be mounted a maximum of four meters apart.
In open spaces (e.g. bus bar sections) there should be an arc sensor approximately every 5
meters. Due to the wide detection range of the sensors and the light reflection inside the
switchgear, the mounting position is not very critical.
