No controller enabling in spite of plugged FIF-cam ring

Question:
Why can the 8200 vector (15-90 kW) not be enabled, although the cam ring(s) are plugged on the FIF-interfaces?

Answer:
When the FIF-cam rings are plugged on, the jumper may be plugged next to the plug connector, so that contact of the corresponding plugs is impossible. Consequently, the controller is not enabled. Check, if the cam rings are plugged correctly on the FIF-interface.
