Safety Precautions
General Safety Statements
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. These precautions must be thoroughly understood, and apply to all phases of operation and maintenance.
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 someone who is capable or rendering aid.
Safety Earth Ground
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.
Safety Symbols
WARNING
Warning notes call attention or a procedure, which if not performed
correctly, could result in personal injury.
i
CAUTION
Caution notes call attention to a procedure, which if not performed
correctly, could result in damage to the equipment.
This symbol appears on the equipment indicating there is
important information in the instruction manual regarding
that particular area.
Note: Calls attention to supplemental informa-
+
tion.
Warning Statement
The following safety warning appears in the text where there is danger to operating and maintenance personnel, and is repeated here for emphasis.
WARNING
Never attempt to connect or disconnect equipment from the
transmission line while RF power is being applied. Leaking RF energy
is a potential health hazard.
Caution Statements
The following equipment cautions appear in the text where the equipment is
in danger of damage and are repeated here for emphasis.
CAUTION
The diode assembly is an ESD sensitive assembly, use proper ESD
precautions.
CAUTION
Do not replace coolant with anything but the specified fluid. The inner
shell of the resistor housing is contoured to the dielectric properties of
this fluid. The use of any other type of coolant will affect the electrical
performance of the load.
