Andrew installation instructions are written for such installation personnel. Antenna systems should be inspected once a year by qualified personnel to verify proper installation, maintenance, and condition of equipment. Andrew disclaims any liability or responsibility for the results of improper or unsafe installation practices. Do not install near power lines. Power lines, telephone lines, and guy wires look the same. Assume any wire or line can Do not install on a wet or windy day or when lightning or thunder is in the area. Do not use metal ladder. Wear shoes with rubber soles and heels. Wear protective clothing including a longsleeved shirt and rubber gloves. Revision History Revision No. Date Description of Changes None May 2005 Released. Bulletin 639510 May 2005 i ATC200-Lite Teletilt® Remote Control Downtilt System May 2005 Bulletin 639510 ATC200-Lite Teletilt® Remote Control Downtilt System Bulletin 639510 May 2005 ATC200-Lite Teletilt® Remote Control Downtilt System WARNING It is very important to disconnect the ATC200-Lite controller from the system after each use to prevent permanent damage to the system. Electric Static Discharge (ESD) can damage or destroy the hardware equipment used for the ATC200-Lite Teletilt® System. ESD can occur during handling of equipment without the user feeling a shock. The following precautions should be taken to prevent ESD. 1. Wear an ESD wrist strap (Figure 1) and/or use a test lead (ground), such as a single-wire conductor with a series resistance of 1 megohm equipped with alligator clips on each end. In using a ground, one end of the alligator clip is connected to a grounded equipment frame and the other end of the alligator clip is touched with a bare hand. 2. Other precautions the user may take to reduce the risk of ESD are: • avoid wearing clothing that conducts a lot of static electricity, such as wool. • remove all jewelry. • avoid handling equipment during an electrical storm. 3. Before opening a package containing an electrostatic unit or an electrostatic sensitive device/assembly, clip the free end of a test lead to the package. Leave the other end connected to the equipment frame or other ESD ground. This will cause any static electricity which may have built up on the package to discharge. Keep the unit package grounded during removal or placement of equipment in the package. 4. Minimize handling of ESDS (Electric Static Discharge Sensitive) equipment. Keep replacement equipment in the electrostatic-free packaging (with ground established between packaging and equipment frame) until needed. Repairable ESD equipment should be placed in the electrostatic-free packaging (with ground connecting package to equipment frame) upon removal from ATC200-Lite system. ESD equipment should only be transported and stored in ESD protective packaging. ATTENTION A OBSERVE PRECAUTION FOR HJMIGUNG ELECTROSTATIC SENSITIVE ÛEVtCES Figure 1. ESD Wrist Strap. iv May 2005 Bulletin 639510 ATC200-Lite Teletilt® Remote Control Downtilt System 5. Always avoid unnecessary movement of body, such as scuffing feet across flooring, when handling ESDS equipment. Such movement will generate additional charges of static electricity. 6. When removing or replacing ESDS equipment, hold the device or assembly through the electrostatic-free wrap, where possible. If this is not possible, lift the device or assembly by its body only. Do not touch component leads, connector pins, or any other electrical connections or paths, even though they are covered by conformal coating. 7. Do not allow ESDS equipment to come in contact with clothing or other ungrounded materials that may have an electrostatic charge. Charges on nonconductive material are not equal. For instance, a plastic storage bag may have a - 10,000 volt potential 1/2 inch from a +15,000 volt potential with many such charges all over the bag. Do not hand ESD equipment to another person until it is safely packaged for protection for ESD. 8. When moving ESDS equipment, always touch the surface on which it rests with bare skin for at least one second before lifting. Before setting it on any surface, touch the surface with your free hand for at least one second. Contact with the bare skin provides a safe discharge path for charges accumulated while you are moving around. 9. While servicing equipment containing ESD devices, do not handle or touch materials such as plastic, vinyl, synthetic textiles, polished wood, fiberglass, or similar items that can generate static charges; unless you repeat the grounding process with the bare hands after contacting these materials. 10. Where possible, avoid repairs that require soldering at the equipment level. Soldering irons must have heater/tips assemblies that are grounded to an electrical ground. Do not use standard plastic solder suckers (special antistatic solder suckers are commercially available). 11. Ground the leads of test equipment momentarily before...
