An IED equipped with optic connections requires a minimum depth of
7.09 inches (180 mm). The allowed minimum bending radius has to be
checked from the optical cable manufacturer.
To rack mount the IED into a 19" equipment frame:
1. Mount the mounting panel into the 19" rack.
2. Loosen the four M5 fixing screws in the case to fit the case into the panel cut-out.
3. Mount the case to the panel cut-out.

Mounting lens sensors for an arc flash detector system

Arc flash detector is used to detect arc situations in air insulated metal-clad switchgear.
The arc flash detector system determines where in the switchgear cubicle the optional
lens sensors are installed. See the application examples in the application manual for
further information on the alternatives.
1. Drill a hole (Ø 10 mm) in the wall of the supervised space.

C ∅ 0.37 inches (9.5 mm)
D 0.75 inches (19 mm)
2. Fit the lens sensor into the hole and fasten it with a self-tapping M3 screw.
Alternatively, the lens sensor can be fastened with a cable tie. To do this, secure
the cable tie to a suitable point of attachment on the cubicle wall and wrap the
cable tie tightly around the sensor.
