Take measures to prevent transient voltage surges of more than 40% of the rated voltage.
This is the case if you only operate devices with SELV (safety extra-low voltage).
Provisions shall be made to prevent the rated voltage from being exceeded by transient
disturbances of more than 119 V.
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.
