/16 Bosch Rexroth AG RC RE 95201/11.07 Safety Notes • Notes on circuitry and on wiring: – The lines used for speed sensors are to be shielded. The shield must be connected to the electronics on one side or to the machine or vehicle ground via a low-resistance connection. – Cables to the electronics must not be routed close to other power-conducting lines in the machine or vehicle. – The electronics and the power outputs of a controller must be fed from the same power source.
