4.2 Ground connection
Minimize noise by connecting the shield and/or the connector
housing and/or the frame to ground. Make sure that ground is not
affected by noise. The connection point to ground can be situated
both on the device side and on user’s side. The best solution to
minimize the interference must be carried out by the user. You are
advised to provide the ground connection as close as possible to the
encoder. We suggest using the ground point provided in the cap (see
Figure, use 1 TCEI M3 x 6 cylindrical head screw with 2 tooth lock
washers).
4.3 Diagnostic LEDs
Five LEDs located in the rear side of the connection cap are
designed to show the operating or fault status of the EtherCAT®
interface.
