6 Assembly
Limited rotation angle of the robot joint.
The rotation angle of the front robot joint is restricted due to the size and position
of the vacuum generator, as well as the cable installation.
• To prevent damage, restrict the rotation angle in the software.
1. Position adapter plate on the robot flange 1 and secure with socket head
screws 4. Tightening torque: 8Nm
2. Plug in distance piece 7 to the vacuum generator 8. (Only robots
UR10/UR10e/UR16e)
3. Position vacuum generator 8 on robot with adapter plate and secure it with
socket head screws aB. Tightening torque: 3Nm.
4. Screw the suction cup with connection 6 into the vacuum port. Tightening
torque: 11Nm

7 Installation
7.1 Pneumatic Installation
Laying cables and tubing
Fig. 3 Laying cables and tubing
The cables and tubing are attached to the outside of the robot arm using the sup
plied Velcro straps.
Note the specified bending radii of the cables and tubing.
The freedom of movement of the robot must not be restricted by the cables and
tubing.
1. Cut the Velcro straps to length.
2. Lay cables and tubing along the robot arm.
3. Secure the cables and tubing with Velcro strips.
7.2 Electrical installation
WARNING!
Risk of Injury due to electric shock.
• For the electric power supply, use SELV or PELV circuits that guarantee a rein
forced isolation from the mains network.
• Switch off power to the controller and safeguard it from being switched on
again unintentionally.
