Safety Precautions
The following are general safety precautions that are not necessarily related
to any specific part or procedure and do not necessarily appear elsewhere in
this publication.
Keep Away From Live Circuits
Operating personnel must at all times observe general safety precautions. Do
not replace components inside equipment with the high voltage supply
turned on. To avoid casualties, always remove power.
Do Not Service Or Adjust Alone
Under no circumstances should any person reach into an enclosure for the
purpose of service or adjustment of equipment except in the presence of who
is capable of rendering aid.
Safety Earth Gound
An uninterruptible earth ground must be supplied from the main power
source to test instruments. Grounding one conductor of a two conductor
power cable is not sufficient protection. Serious injury or death can occur if
this grounding is not properly supplied.
Shock Hazard
Do not attempt to disconnect an RF transmission line while RF power is present. Radiated RF power is a potential health hazard.
Resuscitation
Personnel working with or near high voltages should be familiar with modern
methods of resuscitation.
