Terminology

The terms defined below are used in this document. The definitions given are based

on those found in safety standards.

Service Personnel - The term service personnel applies to trained and qualified

individuals who are allowed to install, replace, or service electrical equipment. The

service personnel are expected to use their experience and technical skills to avoid

possible injury to themselves and others due to hazards that exist in service and

restricted access areas.

User and Operator - The terms user and operator apply to persons other than service

personnel.

Ground(ing) and Earth(ing) - The terms ground(ing) and earth(ing) are synonymous.

This document uses ground(ing) for clarity, but it can be interpreted as having the

same meaning as earth(ing).

Electric Shock Hazard

This equipment meets applicable safety standards.

WARNING:

To reduce risk of electric shock, perform only the instructions that are

included in the operating instructions. Refer all servicing to qualified service

personnel only.

Electric shock can cause personal injury or even death. Avoid direct contact with

dangerous voltages at all times.

Know the following safety warnings and guidelines:

Only qualified service personnel are allowed to perform equipment installation

or replacement.

Important Safety Instructions

vi 4013399 Rev C

Only qualified service personnel are allowed to remove chassis covers and access

any of the components inside the chassis.

Equipment Placement

WARNING:

Avoid personal injury and damage to this equipment. An unstable mounting

surface may cause this equipment to fall.

To protect against equipment damage or injury to personnel, comply with the

following:

Install this equipment in a restricted access location (access restricted to service

personnel).

Make sure the mounting surface or rack is stable and can support the size and

weight of this equipment.

Strand (Aerial) Installation

CAUTION:

Be aware of the size and weight of strand-mounted equipment during the

installation operation.

Ensure that the strand can safely support the equipment’s weight.

Pedestal, Service Closet, Equipment Room or Underground Vault Installation

WARNING:

Avoid the possibility of personal injury. Ensure proper handling/lifting

techniques are employed when working in confined spaces with heavy

equipment.

Ensure this equipment is securely fastened to the mounting surface or rack

where necessary to protect against damage due to any disturbance and

subsequent fall.

Ensure the mounting surface or rack is appropriately anchored according to

manufacturer‟s specifications.

Ensure the installation site meets the ventilation requirements given in the

equipment‟s data sheet to avoid the possibility of equipment overheating.

Ensure the installation site and operating environment is compatible with the

equipment‟s International Protection (IP) rating specified in the equipment‟s data

sheet.

Important Safety Instructions

4013399 Rev C vii

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 is 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

viii 4013399 Rev C

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.
