Automation PC 510 User's Manual V 1.01
When using programmable logic controllers or operating/monitoring devices as control systems in conjunction with
a Soft PLC (e.g. B&R Automation Runtime or comparable product) or slot PLC (e.g. B&R LS251 or comparable
product), the safety precautions applying 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 regu-
lations. The same applies for all other devices connected to the system, such as drives.
All tasks such as installation, commissioning and maintenance are only permitted to be carried out by qualified
personnel. Qualified personnel are those familiar with the transport, mounting, installation, commissioning and
operation of the device who also have the appropriate qualifications (e.g. IEC 60364). National accident prevention
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 Mounting
•
Installation must be performed according to this documentation using suitable equipment and tools.
•
Devices may only 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 according to applicable guidelines (e.g. line cross-section, 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, certain
components must carry dangerous voltage levels of 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 and the uninterruptible power
supply, the housing must be properly grounded (PE rail). Ground connections must be established when testing
operating/monitoring devices or the uninterruptible power supply even when operating them for only 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 (cutout installation) operating/monitoring devices like
the Automation Panel or Power Panel are protected on the front side. The rear side of all devices must be protected
from dust and humidity and cleaned at suitable intervals.
2.6.3 Programs, 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.
