When using programmable logic controllers or operating/monitoring devices as control systems together with a soft
PLC (e.g. B&R Automation Runtime or comparable product) or slot PLC (e.g. B&R LS251 or comparable product),
safety precautions relevant to industrial control systems (e.g. the provision of safety devices such as emergency
stop circuits, etc.) 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 preven-
tion regulations must be observed.
The safety notices, connection descriptions (type plate and documentation) and limit values listed in the technical
data are to be read carefully before installation and commissioning and must be observed.
2.4 Transport and storage
During transport and storage, devices must be protected against undue stress (mechanical loads, temperature,
humidity, aggressive atmospheres, etc.).
2.5 Installation
•
Die Geräte sind nicht gebrauchsfertig und müssen zur Einhaltung der EMV-Grenzwerte entsprechend den
Anforderungen dieser Dokumentation montiert und verdrahtet werden.
•
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).
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.
