Safety Information
Grounding
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 distribu-
tion system, be sure their safety grounds are securely interconnected.
■ LAN cables may occasionally be subject to hazardous transient volt-
ages (such as lightning or disturbances in the electrical utilities power
grid). Handle exposed metal components of the network with caution.
Servicing
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.
