Checklist for machine manufacturer/installer for the
installation of Electro Sensitive Protective Equipment (ESPE)
Dependent upon the application, the below listed checks are a minimum when placing an
ESPE in operation for the first time.
For reference purposes the list should be retained or stored with the machine documents.
1. Are the relevant safety standards incorporated into the machine build?
Will they satisfy the Regulations?
2. Are the standards listed in the Declaration of Conformity?
3. Is the ESPE the correct Type and interfaced to the correct Category?
4. Is access to the danger zone/point of danger only possible through the ESPE?
5. Are measures in place to prevent standing between the ESPE and the danger zone?
If so, are these measures secured against removal?
6. Are additional mechanical protective measures fitted and secured against
manipulation which prevent reaching below, above or behind the ESPE?
7. Has the overall machine stopping time been checked and documented?
8. Is the resultant safety distance observed between the danger point and the ESPE?
9. Is the ESPE correctly fixed and secured against movement after setting in its fixed
position?
10. Are the required protection measures against electric shock in place?
11. Is the re-set/re-start switch for the ESPE installed and fitted to the correct
standard?
12. Are the OSSDs of the ESPE connected in accordance with the machine
circuit diagram?
13. Have the protective functions been inspected in accordance with the inspection
instructions of this document?
14. Are the protective functions effective in every setting of the operating
mode switch?
15. Are the switching elements controlled by the ESPE, e. g. contactors, valves
monitored?
16. Is the ESPE effective during the entire hazardous state?
17. Is the hazardous state ended when the ESPE is switched on or off, as well as
upon changing operation modes or on switching over to another
protective device?
18. Is the Daily Check Requirement sign positioned in a place visible to the
operator?
This checklist does not replace the initial commissioning of regular inspections
by qualified personnel.
