6.1 Safety Instructions
After maintenance and repair work, checks must be carried out to ensure the required
safety level. The valid national or regional work safety regulations must be observed
for this check. The correct functioning of all safety functions shall also be tested.
The purpose of maintenance and repair work is to ensure that the system is kept op-
erational or, in the event of a fault, to return the system to an operational state. Repair
work includes troubleshooting in addition to the actual repair itself.
The following safety procedures and warnings must be observed when working on
the robot arm or control box.

DANGER:
1. Do not change anything in the safety configuration of the soft-
ware (e.g. the force limit). The safety configuration is described
in the PolyScope Manual. If any safety parameter is changed,
the complete robot system shall be considered new, meaning
that the overall safety approval process, including risk assess-
ment, shall be updated accordingly.
2. Replace faulty components using new components with the
same article numbers or equivalent components approved by
Universal Robots for this purpose.
3. Reactivate any deactivated safety measures immediately after
the work is completed.
4. Document all repairs and save this documentation in the tech-
nical file associated with the complete robot system.
