Safety Information
Grounding
Depending on the product model, your product will be classified either as a safety class I or
safety class II compliant device. Class I devices require a connection to earth ground (3-
terminal plug), while class II devices incorporate a 2-terminal plug.
Class I:
There must be an uninterruptible safety earth ground from the main power source
to the product's 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.
Class II:
Safety class II-compliant devices include supplemental insulation to protect
against electric shock, and do not require a connection to earth ground.
For LAN connections:
■
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.
