Safety notice for connecting with a LAN ID (Local Area Network)
A LAN or LAN segment with all the interconnected devices should be contained completely in
a single low voltage power distribution in a building. The LAN is designed either for
"Environment A" according to IEEE802.3 or "Environment 0" according to IEC TR 62102.
Do not connect any electrical connectors directly to the telephone network (telephone network
voltage) or a WAN (Wide Area Network).
Note
Protective ground
A PELV circuit contains a connection to protective ground. Without a connection to protective
ground, or in case there is a fault in the connection to the protective ground, the voltage for the
circuit is not stabilized.
Note
Minimum temperature rating of the cable to be connected to the field wiring terminals, 90 °C.
