Andrew ATC200-Lite manual ESD Wrist Strap

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 dur- ing 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. Figure 1. ESD Wrist Strap.

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 con- nected 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 replace- ment equipment in the electrostatic-free packaging (with ground established between pack- aging 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.
