WARNING
Power supply
The device is designed for operation with a directly connectable safety extra-low voltage
(Safety Extra Low Voltage, SELV) according to UL/IEC 61010‑1 and UL/IEC 61010‑2‑201.
Further notes

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).
