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 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.
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.
The caution symbol appears on the equipment indicating
there is important information in the instruction manual
regarding that particular area.
This symbol appears on the equipment and indicates that the
AC power cord should be removed before servicing the unit.
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. Refer to the Bird web site for
more 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.
WAR NING
Leaking RF energy is a potential health hazard. Never attempt to connect or
disconnect equipment from the transmission line while RF power is being applied.
Severe burns, electrical shock, or death can occur.
See page 11.
WAR NING
High RF voltage and energy is always present in the RF Test Port when the system is
operating. Do not operate the system if the BPM-E RF Test Port is open. Close the port
with a dummy plug or a suitable sampling plug. Failure to comply may result in severe
burns, electrical shock, or death.
See page 12.
ii
WARNING
Dangerous RF voltage. Do not connect or apply an RF signal to the BPM-E
during equipment setup. Failure to comply may result in severe burns, loss of
use of limbs, or death.
See pages 19, 21, and 22.
WARNING
Disconnect the unit from the RF power source and the ac line before any
disassembly. The potential for electrical shock exists.
See page 41.
Caution Statements
The following equipment cautions appear in the text and are repeated here for
emphasis.
CAUTION
BPM-E signal sensing couplers are fixed in place. Do not attempt to remove or
rotate the couplers. They are calibrated and oriented at the factory and are not
designed to be rotated or removed by the end user. Failure to comply may
result in loss of calibration and accuracy, and in permanent damage to the unit.
See pages 12 and 27.
CAUTION
The DC voltage provided by the 3129 Digital Display power/alarm port should
only be used to power the BPM-E. Do not use the 3129 DC source to supply
power to anything else.
See page 15.
CAUTION
Network connections require specific address and protocol information. Have a
qualified IT or network professional perform the BPME ethernet setup. Failure to
comply may result in loss of network communication or the inability to
communicate with the BPME.
See page 22.
CAUTION
Do not use harsh or abrasive detergents for cleaning.
See page 41.

Measures forward power from 2.5 W to 200 kW, measurable reflected
power from 0.25 W to 20 kW (actual measurement ranges depend
upon frequency and line diameter size)
•
Remote monitoring capability
•
Multiple alarm options
•
May be used at any point in the transmission line
•
Available in a variety of line sections
•
Can send an e-mail when an alarm occurs
•
