Product warning labels

The following safety alert label is affixed to each side of the satellite antenna feed arm:

CAUTION

This device emits radio frequency energy Keep two feet (0.6 meters) away from this point Before servicing or upgrading, unplug indoor

power connection

T0145005

This label advises that the antenna emits radio frequency (RF) energy. Because of this potential safety hazard, observe all cautions in the following section ( concerning RF radiation.

Antenna installation safety)

Antenna installation safety

Observe the following precautions when installing the satellite antenna. This manual also includes additional safety alerts where appropriate concerning specific installation procedures.

WARNING

Only HNS-certified installers may install or service DIRECWAY earth stations and components. All HNS-certified installers must expressly acknowledge the HNS requirements for DIRECWAY installations.

DANGER

If you work on a roof, tower, or other high structure or use a ladder or scaffold to access the work site, follow these precautions to prevent personal injury or death:

• Walk only on sound roof structures.

• Make sure the antenna assembly and installation

surface are structurally sound so they can support all loads (equipment weight, ice, and wind).

• Use appropriate safety equipment (for example, a lifeline), depending on the work location.

• Follow all safety precautions from the manufacturers of all safety equipment and other equipment used.

• Perform as many procedures as possible on the ground.

• Important safety information

1035567-0001 Revision A

DANGER

• To avoid electric shock, stay at least 20 ft from power lines.

• If any part of the antenna or mount assembly comes in contact with a power line, call your local power company to remove it. Do not try to remove it yourself.

Failure to heed these warnings could result in serious injury or death.

WARNING

• Do not work in high wind or rain or if a storm, lightning, or other adverse weather conditions are present or approaching.

• Do not attempt to assemble, move, or mount the antenna on a windy day. Even a slight wind can create strong, unexpected forces on the antenna surface.

• Important safety information 1035567-0001 Revision A

CAUTION

Observe these precautions to avoid exposure to RF radiation, a potential safety hazard:

• The antenna must be installed in a location or manner not readily accessible to children and in a manner that prevents human exposure to potentially harmful levels of radiation.

• Antennas mounted in Puerto Rico, the continental United States, or at any site with greater than a 30° elevation angle must be installed such that the lower lip of the antenna reflector is at least 5 ft above any surface upon which a person might be expected to stand, and 3

ft 3 in. from any opening (such as a door or window) in

a building or adjacent structure.

• Antennas mounted in Canada, Alaska, Hawaii, or any site with less than a 30° elevation must be installed such that the lower lip of the antenna reflector is at least 5

ft 9 in. above any surface upon which a person might be expected to stand, and 3 ft 3 in. from any opening (such as a door or window) in a building or adjacent structure.

• The antenna must be mounted such that no object which could reasonably be expected to support a person is within 6 ft 7 in. of the edges of a cylindrical space extending from the antenna reflector.

• If the above distance requirements cannot be met, the antenna must be mounted in a controlled area inaccessible to the general public, such as a fenced enclosure or a roof.

• The antenna must be mounted such that there is no object outside the controlled area which could reasonably be expected to support a person within 6

ft 7 in. of the edges of a cylindrical space extending

from the antenna reflector.

• A fenced installation must have a locked entry, and the fenced area must be large enough to protect the general public from exposure to potentially harmful levels of radiation.

• Important safety information

1035567-0001 Revision A

Failure to observe these cautions could result in injury to eyes or other personal injury.

CAUTION

• All installations of any type or size must carry an industry standard and government approved Radiation Hazard Caution label on the feed arm.

• A fenced or roof installation in a commercial, industrial, or institutional environment must carry a Radiation Hazard Caution sign on the access door, gate, or permanently mounted access ladder that is within plain sight of anyone approaching the antenna from the front or sides of the reflector.

Failure to observe these cautions could result in injury to eyes or other personal injury.

Some installations may require additional precautions. See also the Antenna Site Preparation and Mount Installation Guide (HNS 1035678-0001).

About this document

Scope and audience

Organization

This manual explains how to assemble, install, and point the DIRECWAY for qualified installers who are familiar with satellite antenna installation practices and are capable of properly applying the information presented. The installer may be required to:

• Use a power drill to drill holes into a building.

• Locate studs, rafters, or trusses and drill holes in the exact

center of them.

• Determine whether there are water pipes, electrical wiring, or gas lines hidden in the walls near where you will be drilling.

• Route coaxial cable through the foundation wall, under floors, and through interior walls.

• Ground the satellite antenna and coaxial cable as recommended in the National Electrical Code (published by the National Fire Protection Association, Batterymarch Park, Quincy, MA 02269).

This manual is divided into the following chapters:

• Chapter 1 – Overview includes a summary of the installation steps and tells you where to find information about tasks related to antenna installation.

• Chapter 2 – Antenna parts and required tools describes the components and parts provided in the antenna kit.

• Chapter 3 – Installing the radio and antenna assemblies provides instructions for installing the antenna.

• Chapter 4 – Cabling and connections provides information about making connections to the radio assembly.

• Chapter 5 – Pointing the antenna explains how to point the antenna at the satellite, connect the transmitter, and acquire the satellite signal.

Grounding

Cables and cabling

Factors you should consider in selecting an installation site are discussed in the DIRECWAY Antenna Site Preparation and Mount Installation Guide (HNS

A suitable antenna mount must be installed before the antenna can be installed. For pole mounts that require a concrete base, you must allow at least 24 hr for the concrete to cure before you can install the antenna. Plan accordingly.

For complete information concerning antenna mount installation, including various mounting methods, refer to the DIRECWAY Antenna Site Preparation and Mount Installation Guide. Use only the antenna mount installation methods documented in the DIRECWAY Antenna Site Preparation and Mount Installation Guide.

The entire antenna assembly must be grounded. For grounding information, refer to your training, best grounding practices, and applicable parts of the National Electrical Code (NEC).

For cable specifications, see the IDU manual. How the cable is run depends on the specific installation site. Route and connect the cable according to your training and best practices.
