Chapter 2Installing the Subscriber UnitRUGGEDCOM WIN5158-V-GPSInstallation Guide8 Mounting the Subscriber Unit• Make sure the antenna(s) and subscriber unit are easily accessible for maintenance purposes.• Mount the GPS antenna in a position where the whole sky is visible to the antenna. If the subscriber unit ismounted on a wall and the GPS antenna is mounted on top of the subscriber unit, only half of the sky will bevisible to the antenna. This may not be enough for proper operation.• Conduct a site survey to best position the subscriber unit and antenna(s) in relation to other subscriber units,antennas and base stations in the area. The site survey should also take into consideration the overall safety ofthe selected siteSite SurveyMost wireless networks include many subscriber/base stations installed in various locations in an overlappingradio-cell pattern. It is important to position each subscriber unit in an optimal location considering theassignment of its radio channels. Therefore, a site survey becomes an essential first step before physicallydeploying the subscriber unit.The site survey should include details important to the planning of the subscriber unit deployment in each specificsite, including potential mounting points for the subscriber unit and antennas, as well as the routing options fordata, power and antenna cables.For safety, always consult with the local power utility as well. It is important to select a site that not only offersmaximum coverage, but is also safe for installers to work in.Safety PrecautionsWhen installing the subscriber unit or an antenna, make sure to adhere to the following safety precautions:• Always install the subscriber unit with the help of a partner.• Always use the most appropriate mounting method for the site and the equipment being installed. Forassistance, contact a Siemens representative.• Always assume an overhead line can cause serious injury or death. Note that electric power lines and phonelines look alike.• Always wear the appropriate Personal Protective Equipment (PPE) for the task, including but not limited torubber boots, rubber gloves, hard hat, harness and lanyard, etc.• Always use a ladder made of a non-conductive material, such as wood or fiberglass. Do not use a metal ladder.• Always work under favorable conditions. Do not work on wet or windy days.• If the subscriber unit or antenna begins to drop, step away immediately and allow it to fall. The subscriber unit,cables, metal guy wires and pole (in the case of pole mount installations) are all excellent conductors. Anycontact between these components and an electrical power line will complete an electrical path through thesubscriber unit/antenna and the installer.• If any part of the subscriber unit or an antenna comes in contact with an electrical power line, contact the localpower utility. Do not attempt to touch or remove the component.Section 2.4Mounting the Subscriber UnitThe RUGGEDCOM WIN5158-V-GPS is designed for maximum mounting and display flexibility.
