Action
Refit the connection plate in the base (if it
has been removed).
Use caution and run the cable harness
through the hole in the frame and out to
the base plate.
Make sure that the cables from the axis-1
bracket, runs untangled to all connection
points:
• down through the hole in the frame
to the base plate,
• to the axis-1 motor,
• to the axis-2 motor,
• to the axis-3 motor
• to the SMB/BU recess.
Adjust the cables if needed. The different
cables must not be twisted or tangled.
Do not fasten the axis-1 bracket yet.
Before refitting the R1.MP-A and R1.MP-B
contacts make sure that the hole for pin 1,
as well as the bar code, will be on the left
side. See figure.
