2.5 Mounting
• Installation must take place according to the documentation using suitable equipment
and tools.
• Devices may only be installed without voltage applied and by qualified personnel.
• General safety regulations and nationally applicable accident prevention guidelines must
be observed.
• Electrical installation must be carried out according to the relevant guidelines (e.g. line
cross section, fuse, protective ground connection).
2.6 Operation
2.6.1 Protection against touching electrical parts
To operate programmable logic controllers, operating and monitoring devices, and
uninterruptible power supplies, certain components must carry dangerous voltage levels of over
42 VDC. A life-threatening electrical shock could occur if you come into contact with these parts.
This could result in death, severe injury, or material damage.
Before turning on the programmable logic controller, the operational and monitoring devices and
the uninterruptible power supply, ensure that the housing is properly grounded (PE rail). The
ground connection must be established when testing the operating and monitoring devices or
the uninterruptible power supply, even when operating them for only a short time.
Before turning the device on, make sure that all voltage-carrying parts are securely covered.
During operation, all covers must remain closed.
2.6.2 Programs, viruses and dangerous programs
The system is subject to potential danger 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 preventative
measures such as virus protection programs, firewalls, etc. and obtaining software from reliable
sources.
