Safety Precautions

The following are general safety precautions that are not necessarily related to any specific part or pro-

cedure, and do not necessarily appear elsewhere in this publication. These precautions must be thor-

oughly understood and apply to all phases of operation and maintenance.

Safety Symbols

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.

WARNING

Remove Power

Observe general safety precautions. Do not open the instrument with the power on.

WARNING

Warning notes call attention to a procedure, which if not correctly performed,

could result in personal injury.

Calls attention to supplemental information.

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.

On pages 6, 13, 14 and 16.

On page 6.

On pages 8 and 14.

On page 17

CAUTION

Caution notes call attention to a procedure, which if not correctly performed,

could result in damage to the instrument.

This symbol indicates that a shock hazard exists if the precau-

tions 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.

WARNING

Disconnect the unit from all power sources before servicing. The unit may be

energized from multiple sources. The potential for electric shock exists.

WARNING

Improper wiring could result in electric shock and death.

WARNING

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.

WARNING

If the resistor breaks, there may be splinters or sharp pieces inside the load

housing. Be careful when repairing to avoid being cut.

Caution Statements

The following equipment cautions appear in the text and are repeated here for emphasis.

On page 5.

On page 6.

On pages 6, 7 and 11.

On page 7.

On page 11.

On page 17.

CAUTION

Incorrect hose connections will reverse coolant flow and could destroy the load.

CAUTION

Different control systems are used for 115 Vac and 230 Vac. Use the correct

interlock control for the specific voltage.

CAUTION

If installed, connect optional interlock before applying RF power.

CAUTION

Do not contaminate the coolant with pipe sealant.

CAUTION

Do not interrupt coolant supply. Even momentary application of RF power

while coolant is not circulating could cause immediate destruction of the load

CAUTION

Do not remove the resistor plug. Any attempt to do so will cause leakage and

resistor damage.
