Take care when working near the encoder cables to make sure that they are not
disconnected or damaged. Improper connection or disconnection of encoder
cables may result in erratic motion of the AMR during operation. The AMR
might rotate uncontrollably during loss of encoder signals.
Figure 8-1 shows the location of the drive wheel power and encoder cables, and their con-
nection through the chassis. Disconnecting either cable is typically not required for any normal
maintenance procedure. Disconnecting the encoder cable can lead to loss of control of the
AMR if the cable is not properly reconnected and secured with thread locking fluid.

During initial operation after installation or maintenance, no people or objects
should be within 3 feet of the AMR for safe clearance if a fault occurs.
