In a circuit-breaker cubicle there is a risk of detecting breaking arcs uninten-
tionally, if the detector is placed above the busbars. In such a cubicle it is
better to place the detector at the bottom, see the figure below.
• Use the same mounting bracket as for top mounting but the bend is turned
upwards and the detector placed on the upper side.
• Drill a hole 20 mm (0.79 inches) in front of the busbars, where the detector can
be located.
