1 Safety guidelines
Programmable logic controllers (PLCs), operating/monitoring devices (industrial PCs, HMI) have
been designed, developed and manufactured for conventional use in industrial environments. They
were not designed, developed and manufactured for any use involving serious risks or hazards that
could lead to death, injury, serious physical damage or loss of any kind without the implementation
of exceptionally stringent safety precautions. In particular, such risks and hazards include the use of
these devices to monitor nuclear reactions in nuclear power plants, their use in flight control or flight
safety systems as well as in the control of mass transportation systems, medical life support systems
or weapons systems.
1.1 Policies and procedures
Electronic devices are never completely failsafe. If the programmable control system, operating/
monitoring device or power supply fails, the user is responsible for ensuring that other connected
devices, e.g. motors, are brought to a secure state.
When using programmable logic controllers or operating/monitoring devices as control systems
together with a soft PLC, safety precautions relevant to industrial control systems must be observed
in accordance with applicable national and international regulations. The same applies for all other
devices connected to the system, such as drives.
All tasks such as the installation, commissioning and servicing of devices are only permitted to be
carried out by qualified personnel. Qualified personnel are those familiar with the transport, mounting,
installation, commissioning and operation of devices who also have the appropriate qualifications
(e.g. IEC 60364). National accident prevention regulations must be observed.
The safety notices, information on connection conditions (type plate and documentation) and limit
values specified in the technical data are to be read carefully before installation and commissioning
and must always be observed.
1.2 Installation guidelines
• These devices are not ready for use upon delivery and must be installed and wired according to the
specifications in this documentation in order for the EMC limit values to apply.
• Installation must be performed according to this documentation using suitable equipment and tools.
• Devices are only permitted to be installed by qualified personnel without voltage applied. Before
installation, voltage to the control cabinet must be switched off and prevented from being switched
on again.
• General safety guidelines and national accident prevention regulations must be observed.
• Electrical installation must be carried out in accordance with applicable guidelines (e.g. line cross
sections, fuses, protective ground connections).
1.3 Viruses and dangerous programs
This system is subject to potential risk each time data is exchanged or software is installed from a data
medium (e.g. diskette, CD-ROM, USB flash drive, etc.), a network connection or the Internet. The user is
responsible for assessing these dangers, implementing preventive measures such as virus protection
programs, firewalls, etc. and making sure that software is only obtained from trusted sources.
