Special Use Conditions for ETHERNET Devices

If not otherwise specified, ETHERNET devices are intended for use on local
networks. Please note the following when using ETHERNET devices in your
system:
• Do not connect control components and control networks to an open
network such as the Internet or an office network. WAGO recommends
putting control components and control networks behind a firewall.
• Limit physical and electronic access to all automation components to
authorized personnel only.
• Change the default passwords before first use! This will reduce the risk of
unauthorized access to your system.
• Regularly change the passwords used! This will reduce the risk of
unauthorized access to your system.
• If remote access to control components and control networks is required,
use a Virtual Private Network (VPN).
• Regularly perform threat analyses. You can check whether the measures
taken meet your security requirements.
