Important Safety Instructions
4037424 Rev A ix
Connecting to Utility AC Power
Important: If this equipment is a Class I equipment, it must be grounded.
 If this equipment plugs into an outlet, the outlet must be near this equipment,
and must be easily accessible.
 Connect this equipment only to the power sources that are identified on the
equipment-rating label, which is normally located close to the power inlet
connector(s).
 This equipment may have two power sources. Be sure to disconnect all power
sources before working on this equipment.
 If this equipment does not have a main power switch, the power cord connector
serves as the disconnect device.
 Always pull on the plug or the connector to disconnect a cable. Never pull on the
cable itself.
Connection to Network Power Sources
Refer to this equipment‘s specific installation instructions in this manual or in
companion manuals in this series for connection to network ferro-resonant AC
power sources.
AC Power Shunts
AC power shunts may be provided with this equipment.
Important: The power shunts (where provided) must be removed before installing
modules into a powered housing. With the shunts removed, power surge to the
components and RF-connectors is reduced.
CAUTION:
RF connectors and housing seizure assemblies can be damaged if shunts are
not removed from the equipment before installing or removing modules from
the housing.
Grounding (Utility AC Powered Equipment in Pedestals, Service Closets, etc.)
This section provides instructions for verifying that the equipment is properly
grounded.
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.

Important Safety Instructions
x 4037424 Rev A
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.
Equipotential Bonding
If this equipment is equipped with an external chassis terminal marked with the IEC
60417-5020 chassis icon ( ), the installer should refer to CENELEC standard EN
50083-1 or IEC standard IEC 60728-11 for correct equipotential bonding connection
instructions.
