Safety instructions
The following safety instructions must be followed during installation and working with networks and the
software.
WLAN
• The WLAN stick can be impaired in the vicinity of metal constructions or plants that emit
electromagnetic waves. Plan the distances and use the WLAN stick in such a way that the connection
between the WLAN stick and the WLAN is as unobstructed as possible.
• Do not allow any dust, liquids or vapors that could damage the WLAN stick to get inside it. Use the
WLAN stick together with the CU8210-M001-01x0 cabinet dome in order to protect it against
environmental influences.
• Encrypt the WLAN with the WPA2 security mechanism.
Working with networks
• Restrict access to all devices to an authorized circle of persons.
• Change the default passwords to reduce the risk of unauthorized access. Regularly change the
passwords.
• Protect the devices with a firewall.
• Apply the IT security precautions according to IEC 62443, in order to limit access to and control of
devices and networks.
Working with the software
• Use up-to-date security software. The safe function of the PC can be compromised by malicious
software such as viruses or Trojans.
• The sensitivity of a PC against malicious software increases with the number of installed and active
software.
• Uninstall or disable unnecessary software.
