2.5 Installation
•
Installation must be performed according to this documentation using suitable equipment and tools.
•
Devices are only permitted to be installed by qualified personnel when the power is switched off.
•
General safety regulations and national accident prevention regulations must be observed.
•
The electrical installation must be carried out in accordance with relevant regulations (e.g. wire cross sec-
tion, fuse protection, protective ground connection).
•
Take the necessary protective measures against electrostatic discharge (see
2.6 Operation
2.6.1 Protection against contact with electrical parts
In order to operate programmable logic controllers, operating and monitoring devices and the uninterruptible power
supply, it is necessary for certain components to carry dangerous voltages over 42 VDC. Touching one of these
components can result in a life-threatening electric shock. There is a risk of death, serious injury or damage to
property.
Before switching on the programmable logic controllers, operating and monitoring devices and uninterruptible pow-
er supply, it must be ensured that the housing is properly connected to ground potential (PE rail). The ground
connection must also be made if the operating and monitoring device and uninterruptible power supply are only
connected for testing purposes or only operated for a short time!
Before switching on, live parts must be securely covered. All covers must be kept closed during operation.
2.6.2 Ambient conditions - Dust, moisture, aggressive gases
The use of operating and monitoring devices (e.g. industrial PCs, Power Panels, Mobile Panels, etc.) and unin-
terruptible power supplies in dusty environments must be avoided. This can otherwise lead to dust deposits that
affect the functionality of the device. Sufficient cooling may then no longer be ensured, especially in systems with
an active cooling unit (fan).
The presence of aggressive gases in the environment can also result in malfunctions. In combination with high
temperature and relative humidity, aggressive gases – for example with sulfur, nitrogen and chlorine components
– trigger chemical processes that can very quickly impair or damage electronic components. Blackened copper
surfaces and cable ends in existing installations are indicators of aggressive gases.
When operated in rooms with dust and condensation that can endanger functionality, operating and monitoring
devices such as Automation Panels or Power Panels are protected on the front against the ingress of dust and
moisture when installed correctly (e.g. cutout installation). The back of all devices must be protected against the
ingress of dust and moisture, however, or the dust deposits must be removed at suitable intervals.
2.6.3 Programs, viruses and malicious programs
Any data exchange or installation of software using data storage media (e.g. floppy disk, CD-ROM, USB flash
drive, etc.) or via networks or the Internet poses a potential threat to the system. It is the user's own responsibility to
avert these dangers and to take appropriate measures such as virus protection programs, firewalls, etc. to protect
against them and to use only software from trustworthy sources.
