9.1 Before the initial start-up and following modifications
 Before they begin work, train the operators on their respective tasks. The training is the responsibility of
the operating company.
 Attach notices regarding daily testing in the respective national language of the operator on the machine
in a highly visible location, e.g. by printing out the corresponding chapter (see chapter 9.3).
 Test the electrical function and installation according to this document.
Acc. to IEC TS 62046 and national regulations (e.g. EU directive 2009/104/EC), tests are to be performed
by competent persons in the following situations:
• Prior to the initial start-up
• Following modifications to the machine
• After longer machine downtime
• Following retrofitting or new configuration of the machine
 As preparation, check the most important criteria for the safety sensor according to the following check-
list (see chapter 9.1.1 "Checklist for integrator – to be performed prior to the initial start-up and following
modifications"). Completing the checklist does not replace testing by a competent person!
Not until proper function of the safety sensor is ascertained may it be integrated in the control circuit of the
system.
