19.1.2 Installation and measurement setup
The angular transducer has to be installed directly in front of the rotating shaft (axial alignment) of the
circuit breaker. Before installing the transducer, check that there is enough space for mounting the screw
clamp and the articulating arm.

To install an angular transducer:
1. Attach the flexible coupling and the drill chuck, if necessary, to the rotating shaft of the circuit breaker.
2. Mount the screw clamp and the articulating arm holding the transducer in the optimal position in front
of the rotating shaft on the circuit breaker.
