PRELIMINARY
Safety Instructions
Thunderstorms
DANGER
Avoid working on electrical installations or towers/masts during
thunderstorms.
Thunderstorms create strong electric fields. For that reason, and to
avoid direct strokes of lightning, it is essential that the equipment is
properly earthed for thunderstorm conditions.
2.3.1
Electrostatic Discharge, ESD
CAUTION
Sensitive components such as Integrated Circuits (IC) can be
damaged by discharges of static electricity.
Electrical charges are generated by friction when a body moves, rubs
against clothes, slides against a chair, when shoes rub against the floor,
and when you handle ordinary plastics, etc. Such charges may remain
for a considerable period of time.
Handling of printed board assemblies and IC components
Always use an approved antistatic bracelet to avoid damage to
components mounted on printed board assemblies. The ESD wrist strap
contains a resistor with an ohmic value greater than 1 M
in the cable
to protect the operator. The resistance value is low enough to discharge
the electrostatic voltage. Never replace the cable with any other cable.
The ESD wrist strap must be connected to earth. Ericsson recommends
wrist strap LYB 250 01/14.
Storing and Transporting printed board assemblies and IC Components
Use the original packaging. If this is not available, use a conductive
material, or a special IC carrier that either short-circuits or insulates all
leads of the components.
