• Ensure that the routing and installation of the supply and signal lines are
correct.
The following elements for 24V supply shall be present:
• Outer lightning protection on buildings
• Inner lightning protection of supply lines and signal lines
• Safe electrical separation of 24VDC low voltage through PELV (Protective

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.
