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.
WARNING
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.

Bird 8578 Series RF Load Resistor
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
Do not insert any thin metal objects through the perforated cooling air grilles
while the load is in operation. Otherwise, the power within the unit could arc
over and cause serious bodily injury and/or damage to the unit.
Refer to page 1.
WARNING
Although the interlock terminal is rated to 230 VAC, limit the interlock terminal to
less than 30 Vrms. Otherwise, the potential for electrical shock exists.
Refer to pages 7 and 11.
WARNING
Do not touch the surface of the load. The surface may become hot when power is
applied to load.
Refer to page 12.
WARNING
Disconnect from RF power sources and the AC line before any disassembly or
service. Otherwise, there is a potential for electrical shock.
Refer to pages 13, 14 and 15.
ii
Caution Statements
The following equipment cautions appear in the text and are repeated here for
emphasis.
CAUTION
Do not block air flow. Air enters through perforated grilles at the top of the unit
and exhausts through a lower grill in the unit. Blocking these grilles could
cause unit failure.
Refer to page 7.
CAUTION
Ensure the 115/230 voltage selector on the front panel of the unit is set to the
proper voltage before AC power is applied. Incorrect voltage setting can
permentaly damage the unit
Refer to page 7.
CAUTION
Do not block or restrict the air flow over the resistor array. Otherwise, the load
will overheat and become damaged beyond repair.
Refer to page 11.
CAUTION
Do not apply more than the rated RF power to load. Excessive RF power will
damage the load resistors.
Refer to page 11.
CAUTION
Do not use excessive force, as there is the possibility of the resistors chipping or
cracking
Refer to page 15.
