These are safety class I products and have protective earthing terminals. 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.
LAN cables may occasionally be subject to hazardous transient voltages (such as lightning or disturbances in
the electrical utilities power grid). Handle exposed metal components of the network with caution.
There are no user-serviceable parts inside these products. Any servicing, adjustment, maintenance, or repair
must be performed only by service-trained personnel.
These products do not have a power switch; they are powered on when the power cord is plugged in.
