Electrical Safe Work Practices
Accidents involving electricity can cause burns, explosions, shocks, and death. Only trained and qualified
personnel should service, install, or repair electrical equipment.
The general safety procedures for personnel servicing electronic and electrical equipment include:
• Always turn off or disconnect power before working on electric equipment, electronic circuits, or
any type of electrical item.
• Turn off and disconnect power before checking or replacing fuses.
• Locate and correct the cause of a blown fuse or tripped circuit breaker before replacing the fuse
or resetting the circuit breaker.
• Never defeat the purpose of a fuse or circuit breaker. Always install a fuse with the correct
amperage rating for the circuit. Never install a fuse with a higher rating.
• Always have a second trained and qualified person present when working on electrical systems
(protected or unprotected).
• Always remove metal jewelry, watches, rings, etc., before working on electrical circuits or any
electrical equipment.
• Do not work on electrical equipment in a wet area. Never place containers of liquid on electrical
equipment.
• Do not touch an object that may provide a hazardous path to earth ground.
• Safely discharge capacitors in equipment before working on the circuits (refer to ESD
procedures).
• Inspect cabling for defects, including frayed wiring, loose connections, or cracked insulation.
Replace defective cords and plugs.
• Always check the electrical ratings of equipment and verify that the ratings are correct.
• Never overload circuits.
• Verify grounding of equipment chassis/cabinets. Never cut off or defeat the ground connection on
a plug.
• When working at any site, always observe all safety signs and safety procedures. They exist to
protect personnel from injuries.
• All persons working on or around electrical/electronic equipment should have first aid training,
including resuscitation procedures and external cardiac compression.

Electrostatic Discharge (ESD)
Electrostatic Discharge (ESD) can severely damage sensitive components located on printed circuit cards.
Electrostatic discharge measurements as high as 35,000 volts, can occur from walking across a carpet.
To avoid potential damage to electronic equipment, follow correct electrostatic discharge preventive
procedures when handling or working with the hardware.
• Always wear an electrostatic discharge wrist strap when handling electronic hardware.
• Connect the electrostatic discharge wrist strap to a reliable earth ground.
• Replace worn or frayed electrostatic discharge wrist straps and connecting cords.
• Check your electrostatic discharge strap every month.
• Do not use electrostatic discharge straps that are out of calibration.
• Place printed circuit cards in an electrostatic discharge bag or other ESD container to avoid
damage from stray static charge.
• Do not place printed circuit cards on any surface that is not an approved electrostatic discharge
surface correctly connected to earth ground.
• Always handle printed circuit cards by the edges. Avoid touching any of the sensitive circuits on
the card.
Hazardous Materials
Hazardous materials are likely to be present at the maintenance facility. Many of the following substances
are toxic (causing illness or death): flammable materials, explosive materials, corrosive materials that
cause the skin or eyes to burn on contact, reactive materials that, when exposed to heat, air, water, or
certain other chemicals, can cause burning or release of toxic vapors.
Some hazardous substances are obvious, for example, adhesives, solvents, abrasives, fuels, and pesticides.
Other substances are less obvious, for example, toner in office copiers and printers and heavy-duty
cleaning and disinfectant products. The list of substances identified as hazardous in the workplace is
constantly increasing as new processes and new technologies create new chemicals.
Post a list of hazardous materials in each work area. In the United States, hazardous materials include a
material safety data sheet that describes the material, the health/safety risks, correct usage procedures,
recommended storage facilities, and the method(s) to treat exposure. If local codes do not require use of a
material safety data sheet, a simple list may describe the type of material, correct usage and storage
methods, and its hazard(s). Include emergency first aid procedures in the event that personnel experience
exposure to the material.

Lockout/Tagout Policy
Lockout/Tagout refers to the complete isolation of equipment during maintenance or service work. It is
good practice to require use of locks or tags as warning devices to prevent injuries to service personnel
from accidental machine start-ups.
While servicing equipment, place a red or yellow tag on the equipment, indicating it is out of use for

CHAPTER I
1.0 General Information
1.1 Purpose of Manual
This manual describes the LPA-9600 1 kW Linear Solid State Power Amplifier and includes installation
details, operating instructions and maintenance procedures. Information in this manual applies to all
equipment configurations unless otherwise stated in the text or illustrations. The LPA-9600 is designed
specifically for operation with Sunair Transceivers and Exciters.
1.2 Purpose of Equipment
The purpose of the LPA-9600 is to amplify the low level RF output of a separate exciter to produce 1.0 kW
peak envelope power (PEP) or average power. The LPA-9600 is microprocessor controlled and operates in
the frequency range of 1.6 to 30 MHz. It is intended for a 100% unattended duty cycle for HF
communications systems networks.
1.3 General Description
1.3.1 Physical Description
Outline and mounting dimensions for the LPA-9600 are given in Figure 1.5-1. Control, power and RF
connections to the unit are made on the rear panel.
The LPA-9600 is shown in Figure 1.5-2. The amplifier is a single enclosed unit and is smaller and much
lighter, weighing only 90 lbs., than the traditional amplifiers and power supplies contained in separate units.
Top and bottom covers provide complete access for servicing. Two blowers are provided behind the front
panel filter to force cooling air throughout the amplifier.
1.3.2 Electrical Description
The LPA-9600 1KW Solid State Linear Power Amplifier is a new generation amplifier, combining solid state
RF power amplification and microprocessor technology to produce over 1000 watts of reliable HF power into
a 50 ohm load. The unit operates in the frequency range of 1.6 to 30 MHz and at a rated output of 1.5 to 1
VSWR. Four amplifier/power supply modules, each capable of producing over 300 watts, in combination
deliver a very conservative 1000 watts of peak envelope or continuous RF output power.
The LPA-9600 operates from 115 or 230 VAC (50 to 60 Hz). It is extremely rugged and withstands
temperatures up to +65°C (+149°F) while operating at a 100% duty cycle. Forced air cooling, under
microprocessor control, is utilized to maintain safe operating temperature.
The unit is capable of providing a reduced power mode (500 watts) and a bypass mode (65 or 125 watts) that
is locally keyboard selected. Also available by keyboard are status indications of power, individual amplifier
voltages and currents. The liquid crystal display (LCD) indicates the specific function selected.
Sophisticated diagnostics, status monitoring and routine housekeeping are all under microprocessor and
software control. In the event of malfunction the LPA-9600 automatically selects the next lower safe
operating level, flashes a warning light locally, and displays the cause of the malfunction on the LCD. If the
malfunction is caused by more than one failure, the operator or technician is able to obtain detailed
diagnostics by use of the keyboard.

1.3.2.1 Expected EMP Performance
The LPA-9600 is designed with an EMP environment in mind. All control and power lines into and out of
the LPA-9600 are filtered. This filtering on the standard unit is adequate for a mild EMP. But for full EMP
hardening, the optional EMP filter, which replaces the existing filter, is required. This filter is designed per
approved EMP techniques and decouples every input and output line (except the antenna).
Although the output elements in the LPA-9600 are solid state rather than vacuum tube, they are adequately
protected from EMP damage by shielding and specially designed filtering and decoupling of all interface
lines.

2.4 General Installation Information
Satisfactory operation of your equipment depends on the care and thoroughness taken during installation.
2.4.1 Station Layout
The LPA-9600 must be installed in a structure which provides protection from the weather. Ambient temperature
must be maintained between - 30°C (-22°F) and +65°C (144°F).
Refer to Figure 1.5-1 to see the necessary outline dimensions required for installation. Floor load is 90 pounds.
Allow free circulation of air around the cabinet, and at least six inches air space between the back of the unit and
any wall or partition. The companion transceiver may be placed on top of the LPA-9600 for voice or CW modes
of communications. For FSK or other modes requiring a full kilowatt of average power output, the transceiver
should be located on an adjacent table and have a blower kit. The transceiver may also be rack-mounted above
the LPA-9600 if blowers are provided in the top of the rack.

2.5 Configurations
Figure 2.6-1 through Figure 2.6-3 are illustrations of various LPA-9600 configurations.
2.6 Antennas and Ground Systems
The LPA-9600 is designed to work with two types of antenna:
• Non-resonant antennas where an antenna coupler is used.
• Broadband antennas where the LPA-9600 is connected directly to the antenna.
Figure 2.6-1 through Figure 2.6-3 illustrate configurations where each of these two types of antennas are used.
2.6.1 Random Length Non-Resonant Antennas
The antenna impedance of non-resonant antennas is dependent on the operating frequency. An antenna coupler
must be used to match the antenna to the LPA-9600. Thirty-five foot whip antennas offer a good compromise
between practical height and good electrical performance at low operating frequencies. The performance of the
35-foot whip is greatly influenced by its ground system. For Base Station roof top installation, see Figure 2.6-2
for grounding details.
Another non-resonant antenna is the longwire. The two most popular length longwire antennas are 75 and 150
feet. Both of these antennas require an antenna coupler to match the antenna to the LPA-9600. Figure 2.6-4 is an
illustration of a 75-foot longwire installation. Note that the feed line from the antenna to the coupler is part of the
antenna’s length.
2.6.2 Broadband 50 Ohm Antennas
These are generally complex, expensive antennas requiring a large area for installation. Their use is usually
limited to high performance base station installations which must operate at diverse frequencies. As this class of
antenna has approximately 50 ohm output impedance over the rated band of frequencies, an antenna coupler is not
required. Some common types of broadband antenna are the Discone and Log-Periodic. Figure 2.6-1 is an
example of a system configuration utilizing a broadband antenna.
