about the product.
WARNING
A WARNING in the manual denotes a hazard that can cause injury or
death.
CAUTION
A CAUTION in the manual denotes a hazard that can damage
equipment.
Do not proceed beyond a WARNING or CAUTION notice until you have
understood the hazardous conditions and have taken appropriate steps.
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.
