2.6 Operation
2.6.1 Protection against touching electrical parts
To operate programmable logic controllers, operating/monitoring devices or uninterruptible power supplies, it is
necessary for certain parts to carry dangerous voltage levels over 42 VDC. Touching one of these parts can result
in a life-threatening electric shock. This could lead to death, severe injury or damage to equipment.
Before turning on the programmable logic controller, operating/monitoring devices or the uninterruptible power
supply, the housing must be properly grounded (PE rail). Ground connections must be established even when
testing or operating operating/monitoring devices or the uninterruptible power supply for a short time!
Before turning the device on, all parts that carry voltage must be securely covered. During operation, all covers
must remain closed.
2.6.2 Environmental conditions - Dust, humidity, aggressive gases
The use of operating/monitoring devices (e.g. industrial PCs, Power Panels, Mobile Panels, etc.) and uninterruptible
power supplies in very dusty environments should be avoided. Dust collection on the devices can affect functionality
and may prevent sufficient cooling, especially in systems with active cooling systems (fans).
The presence of aggressive gases can also lead to malfunctions. When combined with high temperature and
humidity, aggressive gases – e.g. with sulfur, nitrogen and chlorine components – can induce chemical reactions
that can damage electronic components very quickly. Signs of the presence of aggressive gases are blackened
copper surfaces and cable ends on existing equipment.
For operation in dusty or humid conditions, correctly installed (e.g. cutout installations) operating/monitoring devices
like the Automation Panel or Power Panel are protected on the front. The back of all devices must be protected
from dust and humidity and cleaned at suitable intervals.
2.6.3 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.
