These are safety class I products and have protective earthing termi-
nals. There must be an uninterruptible safety earth ground from the
main power source to the product’s input wiring terminals, power
cord, or supplied power cord set. Whenever it is likely that the
protection has been impaired, disconnect the power cord until the
ground has been restored.
For LAN cable grounding:
■ If your LAN covers an area served by more than one power
distribution system, be sure their safety grounds are securely
interconnected.
