Note to cable length | Signal cable lengths to the sensor / encoder over 3 m must be shielded, the shield design must be in line with the state of the art and be effective. For larger cable lengths > 30 m, a suitable surge protection should be provided if appropriate interference could affect the signal cable. |

EMC notes | In case of push-in and mini-TC connectors, ESD air discharges conforming to EN 61000-6-4 into the connectors or to the lines connected there can lead to measurement deviations up to ±FSV within the respective channel or to other channels by crosstalk. Peak voltages (surge) conforming to EN 61000-6-2 that are applied to the cable shield can lead to measurement deviations up to ±FSV. |
