Part 2: Maintenance 3. Replacing the Cable Unit
97
Installation
(1) Pass the cables of the new cable unit through the cable bracket and nut. Fasten the
duct joint to the cable bracket.
(2) Pass the cables through the base connector plate and fasten the main cable elbow
fitting using four bolts (M6
×
12).
(3) Referring to the wiring schematics in the following pages, connect the connectors
properly.
CAUTION
Connect the signal cable securely. Do not put anything heavy on the signal cable
or bend it too much. This may damage the signal cable. If abnormality occurs in
the signal cable, the robot may malfunction.
(4) Referring to the Wiring Schematic 1 in the next page, connect the ground wires and
pneumatic tubes properly.
(5) Mount the receptacle on the base connector plate using four bolts (M3
×
8).
(6) Bind the cables with wire ties as they were before the unit replacement. The
following must be paid attention to when binding the cables with a wire tie:
The cables must not touch the pulley, timing belt or other movable parts or areas.
Do not pinch the cables when closing the cover.
Do not allow unnecessary strain on the cables. The cables must be arranged as
such so that they will not be forcibly bent. Unnecessary strain on the cables may
cause wire disconnection inside.
The cables inside the duct must be long enough so that the cables will not be pulled.
(7) Attach the cable bracket to the arm using three bolts (M4
×
8).
(8) Fasten the duct joint using a spanner (double side 51mm wide) or a pair of pliers.
(9) Place the base connector plate back to where it was and fasten it.
(10) Reinstall the arm top cover to complete the reassembly.
