Safety Precautions

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.
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.
Shock Hazard
Do not attempt to remove the RF transmission line while RF power is present.
Capacitors can store a dangerous electrical charge. Avoid contact with all system capacitors. If it
is necessary to perform work near a system capacitor, be sure to discharge the capacitor through
a low resistance.
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.
Resuscitation
Personnel working with or near high voltages should be familiar with modern methods of
resuscitation.
Remove Power
Observe general safety precautions. Do not open the instrument with the power on.

injury.
Cautions call attention to a procedure, which if not correctly performed could result in damage
to the instrument.
Notes call attention to supplemental information.
The caution symbol appears on the equipment indicating there is
important information in the instruction manual regarding that
particular area.
Safety Precautions
iii
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.
The load weighs 236 lbs (107 kg), do not attempt to lift alone. Two or more people, or
mechanical assistance, are required to lift the load. Injury may result from attempting to lift
alone.
See pages 3, 5, and 15.
The vent plug must be installed at all times when the unit is in operation or cooling.
Always check to ensure vent plug is installed prior to operation.
Failure to do so WILL result in damage to the equipment and endanger the operator’s safety.
See pages 4, 6, and 16.
Turn off AC power and RF power when attaching the power cable.
See page 7.
Do not touch the load during operation. During operation, load surfaces are extremely hot.
Touching the load during or after operation may cause burns.
See page 8.
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.
See pages 7, 8, and 10.
Disconnect the unit from all power sources before servicing. The unit may be energized from
multiple sources. The potential for electric shock exists.
See pages 10, 12, 13, 13, 15, 16, 16, and 18.
Do not operate with side panel removed. Doing so could result in personal injury.
See page 12.

Caution Statements
The following equipment cautions appear in the text whenever the equipment is in danger of damage and are
repeated here for emphasis.
Maximum power is 3,700 W when the blower is not running. If the indicator light should turn
off, immediately reduce RF pwer to less than 3,700 W.
See page 2.
Do not block airflow. The air intake vent on the bottom of the load must not be obstructed.
See page 3.
This load is designed for operation in a horizontal position only, with the vent plugs up. Do not
use in any other manner.
See page 4.
Blocking should be used to support the load to avoid damage to the RF connector.
The RF connector extends from the front of the load.
See page 5.
Blocking should be used to support the load to avoid damage to the thermoswitch.
The thermoswitch extends from the back of the load.
See page 5 and 15
If installed, connect optional interlock before applying RF power.
See page 6 and 8.
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.
See page 7.
Do not use a cleaning solution that will damage the plastic parts of the fan.
See page 12.
Use only Bird coolant, P/N 5-1070, to prevent damage to the load.
See page 13.
