2.1.2 Sensor Placement
Sensors need to be mounted to provide full coverage of the switchgear cubicles to be protected.
Where the protected zone is larger than the sensor coverage then the use of multiple sensors is
required.
Precise positioning of the sensors is generally not required as the light caused by the arc is reflected from
the walls.
2.1.3 Sensor Mounting
The RA30 is suitable for flush panel mounting in a number of configurations, for further
