kuka saferobot v2.1.4

I bought a safety robot VKR210-2 2000 ED05, but he can not move right now. I want to know how to shorten the plug below him and how his RDW needs to be dealt with before it can move and hope that most of my friends can help me. I will be very grateful.

This security robot is in the popular version. I really don't know how to let the security robot move. I am very distressed and hope to get your help. Brother. very much
