Qualified Personnel
Only qualified, trained electricians knowledgeable in the safety standards of automation systems may
configure, install, set up, maintain, and test the devices. The requirements concerning qualified per-
sonnel are dependent on the requirements profiles described in ZVEI and VDMA. For this reason,
electricians must know the contents of the manual "Weiterbildung in der Automatisierung" (Further
Training in Automation Systems) published by ZVEI and VDMA published by Maschinenbau-Verlag,
Post Box 710864, 60498 Frankfurt, Germany) before installing and maintaining the devices. These are
specialists who are capable of assessing the work to be done and the possible dangers on account of
their technical training, knowledge, experience, and knowledge of the relevant standards; or who have
an identical level of knowledge equivalent to technical training since they have worked in the same
area for many years.
Only Murrelektronik technical personnel are allowed to execute work on the hardware and software of
our devices, if they are devices not described in this manual.
Unqualified tampering with the hardware or software, or failure to observe the warn-
ings cited in this manual may result in severe personal injury or damage to property.
