- 1) For more detailed information on the exact configuration of your machine/unit, please consult your relevant SICK branch office.2) The enclosure rating (in accordance with IEC 60529) is achieved with attached mating connector and was tested with the shaft in a horizontal position.3) The values displayed apply to a diagnostic degree of coverage of 90%, which must be achieved by the external drive system. In the event of resonance, suitable tests have to be carried out on the entire drive system.

- 1) The EMC according to the standards quoted is achieved when the motor feedback system is mounted in an electrically conductive housing, which is connected to the central earthing point of the motor controller via a cable screen. The GND-(0 V) connection of the supply voltage is also grounded here. If other shielding concepts are used, users must perform their own tests.
