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. These precautions must be throughly understood and ap
plied to all phases of operation and maintenance.
Keep Away From Live Circuits
Operating personnel must at all times observe normal safety regulations. Do
not replace components or make adjustments to the 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 of rendering aid.
Safety Earth Ground
An uninterruptible earth safety 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 remove the RF transmission line while RF power is pres
ent. Radiated RF power is a potential health hazard.
Safety Symbols
WARNING
Warning notes call attention to a procedure, which if not correctly
performed could result in personal injury.
CAUTION
Caution notes call attention to a procedure, which if not correctly
performed could result in damage to the instrument.
This symbol appears on the equipment indicating there is
important information in the instruction manual regarding
that particular area.

Warning Statements
Note: Calls attention to supplemental informa
+
tion.
-
The following safety warnings appear in the text where there is danger to op
erating and maintenance personnel and are repeated here for emphasis.
WARNING
Do not insert a screwdriver or any thin metal objects through the
perforated cooling air grilles while the load is in operation. The power
within the unit could arc over and will cause serious injury to
personnel and damage to the unit.
WARNING
Disconnect this unit from RF power sources before any disassembly for
repair or replacement procedures. The potential for electrical shock
exists.
WARNING
Surface can reach temperatures in excess of 100°C when maximum
power is applied to load.
WARNING
Limit the interlock terminal to less than 30 Vrms. Although the
interlock terminal is rated to 230 Vac, the potential for electrical shock
exists.
Caution Statements
The following equipment cautions appear in the text whenever the equipment
is in danger of damage and are repeated here for emphasis.
-
CAUTION
Connect interlock before RF operation.
CAUTION
Do not apply more than the rated RF power to load. Excessive RF
power will damage the load resistors.
CAUTION
Do not block airflow. Air enters the housing through perforated grilles
at the side of the unit and exhausts through the opposite grille of the
unit. Blocking these grilles could cause unit failure.
