Important Safety Instructions
Safety Plugs (USA Only)
This equipment may be equipped with either a 3-terminal (grounding-type) safety
plug or a 2-terminal (polarized) safety plug. The wide blade or the third terminal is
provided for safety. Do not defeat the safety purpose of the grounding-type or
polarized safety plug.
To properly ground this equipment, follow these safety guidelines:
Grounding-Type Plug - For a 3-terminal plug (one terminal on this plug is a

protective grounding pin), insert the plug into a grounded mains, 3-terminal
outlet.
Note: This plug fits only one way. If this plug cannot be fully inserted into the
outlet, contact an electrician to replace the obsolete 3-terminal outlet.
Polarized Plug - For a 2-terminal plug (a polarized plug with one wide blade

and one narrow blade), insert the plug into a polarized mains, 2-terminal outlet
in which one socket is wider than the other.
Note: If this plug cannot be fully inserted into the outlet, try reversing the plug.
If the plug still fails to fit, contact an electrician to replace the obsolete 2-terminal
outlet.
Grounding Terminal
If this equipment is equipped with an external grounding terminal, attach one end of
an 18-gauge wire (or larger) to the grounding terminal; then, attach the other end of
the wire to a ground, such as a grounded equipment rack.
Safety Plugs (European Union)
Class I Mains Powered Equipment – Provided with a 3-terminal AC inlet and

requires connection to a 3-terminal mains supply outlet via a 3-terminal power
cord for proper connection to the protective ground.
Note: The equipotential bonding terminal provided on some equipment is not
designed to function as a protective ground connection.
Class II Mains Powered Equipment – Provided with a 2-terminal AC inlet that

may be connected by a 2-terminal power cord to the mains supply outlet. No
connection to the protective ground is required as this class of equipment is
provided with double or reinforced and/or supplementary insulation in
addition to the basic insulation provided in Class I equipment.
Note: Class II equipment, which is subject to EN 50083-1, is provided with a
chassis mounted equipotential bonding terminal. See the section titled
Equipotential Bonding for connection instructions.
