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 thoroughly understood and apply to all phases of operation and maintenance.
WARNING
Keep Away From Live Circuits
Operating Personnel must at all times observe general safety precautions. Do not replace
components or make adjustments to the inside of the test equipment with the high voltage
supply turned on. To avoid casualties, always remove power.
WARNING
Shock Hazard
Do not attempt to remove the RF transmission line while RF power is present.
WARNING
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.
WARNING
Safety Earth Ground
An uniterruptible 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.
WARNING
Resuscitation
Personnel working with or near high voltages should be familiar with modern methods of
resuscitation.
WARNI NG
Remove Power
Observe general safety precautions. Do not open the instrument with the power on.
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.
Note: Calls attention to supplemental information.
i
This symbol indicates that a shock hazard exists if the precautions in the
instruction manual are not followed.
The caution symbol appears on the equipment indicating there is important
information in the instruction manual regarding that particular area.
This symbol indicates that the unit radiates heat and should not be touched
while hot.
This symbol appears on the equipment and indicates the requirement for
separate collection of discarded electrical and electronic equipment in
accordance with the European Union Directive 2002/96/EC.
Warning Statements
The following safety warnings appear in the text where there is danger to operating and maintenance personnel, and are repeated here for emphasis.
WARNING
The vent plug must be used at all times when the unit is operating or cooling. Failure to do
so could result in an explosion or severe burns.
On page 5 and 6.
WARNI NG
Never attempt to connect or disconnect RF equipment from the transmission line while RF
power is being applied. Leaking RF energy is a potential health hazard.
On page 7, 9, 11, 13 and 14.
WARNING
Turn off AC power and RF power when attaching the power cable.
On page 8.
WARNING
Disconnect the blower assembly from supply voltage before performing any maintenance.
On page 13
WARNING
Disconnect the unit from all power sources before servicing. The unit may be energized
from multiple sources. The potential for electric shock exists.
On page 14, 15, 16 and 17.
WARNING
Do not operate with side panel removed. Doing so could result in personal injury.
On page 14.
ii
Caution Statements
The following equipment cautions appear in the text and are repeated here for emphasis.
CAUTION
This load is designed for operation in a horizontal position only, with the vent plug up. Do
not use in any other manner.
On page 5.
CAUTION
Do not contaminate the coolant with pipe sealant.
On page 6.
CAUTION
If installed, connect optional interlock before applying RF power.
On page 6.
CAUTION
Check the local electrical code for proper AC hookup prior to operation of the unit. Make
sure the neutral or return hookup is only used for that purpose.
On page 8.
CAUTION
Make sure the interlock is properly connected when overloaded to prevent damage to the load.
On page 9.
CAUTION
Maximum power is 1,250 W when the blower is not running. If the indicator light should
turn off, immediately reduce RF power to less than 1,250 W.
On page 11.
CAUTION
Use only Bird coolant, P/N 5-1070, to prevent damage to the load.
