The following are general safety precautions that are unrelated to specific procedures and therefore do not appear 
elsewhere in this publication.  These are recommended precautions that personnel should understand and apply during 
through the many phases of operation and maintenance. 
 

 
Since most modules used in all models of equipment have Electrostatic Discharge (ESD) sensitive devices included in 
them, all modules should be considered sensitive to electrostatic discharge.  Handling in the field shall be the same as in 
the factory.  Each system is shipped with a wrist strap that must be worn while maintaining the equipment.  The wrist 
strap shall be fastened to the equipment chassis either in the designated plug-in or attached to the equipment chassis 
with the alligator clip.  The wrist strap must be used before any modules are removed from the equipment and at all times 
while handling the modules until they are placed in a protective environment such as an anti-static bag.  Modules or 
boards must not be placed on any non-conducting surface such as wooden work benches, painted metal work benches, 
plastics, or technical manuals.  Any work surface to be used must have a conducting mat placed on it and attached to 
earth ground.  The mat and additional wrist straps can be obtained from  SELEX Sistemi Integrati Inc. 
 

 
Operating personnel must at all times observe all safety regulations.  Under no circumstances should any person remove 
any protective covers that expose lethal voltages.  Do not replace components or make adjustments inside the equipment 
with primary power supply turned on.  Under certain conditions, dangerous potentials may exist when the power is in the 
off position, due to charges retained by capacitors.  To avoid casualties, always remove power and allow time for the 
capacitors to discharge before touching it. 
 

 
Under no circumstances should any person reach into or enter the enclosure for the purpose of servicing or adjusting the 
equipment except in the presence of someone who is capable of rendering aid. 
 

 
Personnel working with or near high voltages should be familiar with modern methods of resuscitation.
