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 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.
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.
