INSTRUCTION MANUAL

RWARNING HIGH VOLTAGE! NEVER
attach an antenna or internal antenna connector dur-
ing transmission. This may result in an electrical
shock or burn.
RWARNING! NEVER carry the linear amplifier
by yourself. At least two persons must carry the linear
amplifier since it weights approx. 25 kg (55 lb).
RWARNING! NEVER apply AC voltage until the
linear amplifier is grounded. Touching the linear ampli-
fier may result in an electrical shock.
RNEVER apply AC voltage that exceeds the sug-
gested voltage. This could cause a fire or ruin the
IC-PW1/EURO.
RNEVER use an extension cord with the AC power
cable. Extension cords may cause fire or electrical
shock.
RNEVER let metal, wire or other objects touch any
internal part or connectors on the panel of the linear
amplifier. This will cause electric shock.
RNEVER expose the linear amplifier or remote con-
troller to rain, snow or any liquids.
NEVER allow children to play with the linear amplifi-
er or remote controller.
DO NOT operate the IC-PW1/EURO before adjusting
the [ALC adj1] and [ALC adj2] pots properly on the
rear panel of the linear amplifier.
AVOID using or placing the linear amplifier or remote
controller in areas with temperatures below –10°C
(+14°F) or above +40°C (+104°F).
AVOID placing the linear amplifier or remote controller
in excessively dusty environments or in direct sunlight.
AVOID placing the linear amplifier against walls or
putting anything on top of the linear amplifier. This will
obstruct heat dissipation.
BE CAREFUL! The linear amplifier will become hot
when operating if continuously for long periods.
BE CAREFUL! Set the transceiver’s (exciter’s) RF
output power to less than 100 W, otherwise, the IC-
PW1/EURO will be damaged.
During maritime mobile operation, keep the linear
amplifier, remote controller and microphone as far
away as possible from the magnetic navigation com-
pass to prevent erroneous indications.
The IC-PW1/EURO cannot be used with the AH-2 HF
AUTOMATIC ANTENNA TUNER.
For U.S.A. only

2INSTALLATION AND CONNECTIONS
■Unpacking
After unpacking, immediately report any damage to the
delivering carrier or dealer. Keep the shipping cartons.
For a description and a diagram of accessory equip-
ment included with the IC-PW1/EURO, see SUP-
PLIED ACCESSORIES on p. ii of this manual.
■Ferrite core installation
The supplied cable ties (oin SUPPLIED ACCES-
SORIES) should be attached to the AC cable of the
IC-PW1/EURO as illustrated below.
NOTE: Only one ferrite core is attached with the IC-
PW1EURO.
■ OPC-853 AC cable with line filter
The IC-PW1EURO must be used with the OPC-853
AC cable to satisfy European R&TTE requirements.
■Selecting a location
Select a location for the linear amplifier that allows
adequate air circulation, free from extreme heat, cold,
or vibrations, and away from TV sets, TV antenna ele-
ments, radios and other electro-magnetic sources.
The linear amplifier and remote controller sections of
the IC-PW1/EURO can be separated. The remote
controller can be placed near the operator for easy
monitoring of linear amplifier conditions at any time.
See p. 10 for separation instructions.
The linear amplifier must be placed on a solid founda-
tion since it is very heavy.
■AC power cable connection
A suitable AC power plug must be connected to the
AC power cable end. See the diagram below for con-
nection procedures. AC input voltage is automatically
selected.
The IC-PW1/EURO can accept either 100–120 V AC
or 200–240 V AC power.* However, we recommend
using 200–240 V AC rather than 100–120 V AC for
better power supply efficiency and longer periods of
transmission.
* Europe version: 230 V AC only
DDSingle-phase 3-wire line (200–240 V AC)
qThe green wire from the AC power cable must be
connected to the protective earth.
wThe black and white wires from the AC power cable
can be connected to either terminal.
*Use the appropriate AC plug if required.
DDSingle-phase 2-wire line (100–120 V AC)
qThe green wire from the AC power cable must be
connected to the protective earth.
wThe black wire from the AC power cable must be
connected to the hot (live) wire.
eThe white wire from the AC power cable must be
connected to the return wire.
DDThree-phase 3-wire line (200–240 V AC)
qThe green wire from the AC power cable must be
connected to the protective earth.
wThe black and white wires from the AC power cable
can be connected to 2 of 3 wires.

Ferrite core
Attach and position

Cut the cable ties
so that enough
length remains to
secure the ferrite
core in place.

■Grounding
To prevent electrical shock, television interference
(TVI), broadcast interference (BCI) and other prob-
lems, ground the linear amplifier through the
GROUND terminal on the rear panel.
For best results, connect a heavy gauge wire or strap
to a long earth-sunk copper rod. Make the distance
between the GROUND terminal and ground as short
as possible.
RWARNING: NEVER connect the
GROUND terminal to a gas or electric pipe, since
the connection could cause an explosion or electric
shock.
■Antenna
For radio communications, the antenna is of critical
importance, along with output power and sensitivity.
Select antenna(s), such as a well-matched 50 Ω
antenna with more than 2 kW power rating, and feed-
line. 1.5:1 of Voltage Standing Wave Ratio (VSWR) is
recommended for a desired band. Of course, the
transmission line should be a coaxial cable.
When using 1 antenna, use the [ANT1] connector.
CAUTION: Protect your linear amplifier from
lightning by using a lightning arrestor.

eSlide the connector body on and solder it.
rScrew the coupling ring onto the connector body.
Antenna SWR
Each antenna is tuned for a specified frequency
range and SWR may be increased out-of-range.
When the SWR is higher than approx. 2.0:1, the lin-
ear amplifier’s power drops to protect the final FET.
In this case, an antenna tuner is useful to match the
linear amplifier and antenna. Low SWR allows full
power for transmitting even when using the antenna
tuner. The IC-PW1/EURO has an SWR meter to
monitor the antenna SWR continuously.

■System interconnections
1 or 2 Icom 100 W HF transceivers can be connected
as exciters to the IC-PW1/EURO. Non-Icom trans-
ceivers can be used, however, band selection will not
be synchronized for each exciter.
See the following diagrams for making connections
between the IC-PW1/EURO and an exciter (transceiv-
er). See p. 5 for AC power cable connection.

INSTALLATION AND CONNECTIONS
•Using non-Icom exciters (transceivers) when the IC-PW1/EURO’s power is OFF
To use the antenna selector of the IC-PW1/EURO
while the power is OFF, follow 1 of 2 methods.
(1) Supply the antenna selector power to the
ACC-1 socket
Supply the 13.8 V DC, 0.5 A to pin 7 of the [ACC-1]/
[ACC-2] socket.
- Use [ACC-1] when the exciter is connected to [INPUT1].
- Use [ACC-2] when the exciter is connected to [INPUT2].
(2) Use the auxiliary power supply
Set the jumper to ‘2’to use the auxiliary power sup-
ply as shown at right.
-The antenna selector functions even when the IC-
PW1/EURO power is OFF
In addition set the jumper on the IC-PW1/EURO con-
troller to ‘2’to turn the controller’s LEDs OFF as
shown at right.
When the jumper is set to ‘2,’the CI-V control does
not function even if an Icom exciter is connected.
These diagrams show the factory defaults.

3OPERATION
The IC-PW1/EURO uses CI-V frequency data for
automatic selection of the operating band. Program
the exciter’s address to use this capability as follows:
For non-Icom exciters, the IC-PW1/EURO cannot
be controlled using the CI-V function, so this set-
ting is not necessary.
For transceivers which have multiple antenna con-
nectors for specified bands (e.g. IC-726, IC-729,
etc.), set the same as for 2 Icom exciters.
DSetting the Icom exciters
When connecting 2 or more CI-V devices:
DO NOT use the “AUTO”baud rate for CI-V
devices. We recommend that all CI-V devices are
set to 9600 bps.
•When using the same baud rate, the exciters’fre-
quencies are synchronized.
•When using different baud rates (i.e. 4800 and
9600 bps, etc.), the exciters’frequencies are not
synchronized.
qConfirm that the exciter’s CI-V transceive function
is ON.
- Refer to the instruction manual for details.
w When connecting 2 exciters, connect the 1st and
2nd exciter to [INPUT1] and [INPUT2], respectively.
eWhen connecting 2 Icom exciters, set [EXCITER]
to the [1&2] position.
rWhen connecting 2 or more CI-V devices, DO
NOT set to “AUTO”baud rate.
- Refer to the instruction manual for details.
- When using the same baud rate, the exciters’fre-
quencies are synchronized.
- When using different baud rates (i.e. 4800 and 9600
bps, etc.), the exciters’frequencies are not synchro-
nized. [INPUT z] and [INPUT x] selection is automat-
ically selected using the exciter’s baud rate.
•DO NOT USE CT

OPERATION
■Programming the CI-V address (continued)
DSetting the IC-PW1/EURO’s address
It is not necessary to change the IC-PW1/EURO’s
default CI-V address of 54H. However, if desired, the
address can be changed using the internal address
switch illustrated below.
It is not necessary to change the IC-PW1/EURO’s
default CI-V address (default S3=5, S4=4). However,
in the case when you will connect two (2) IC-
PW1/EUROs like as above left1, please set a differ-
ent address number using the internal address switch
as illustrated as above right.
NOTE: Turn the power OFF when you are going to
change the address setting, then programming the
CI-V address again.
ïOther NOTE:
•IC-781;
NEVER TURN THE POWER OFF of the IC-781 dur-
ing the operation when you are using the IC-781 as
one of the exciters, otherwise the CI-V control may
be interrupted.
•Baud rate;
Higher baud rate (e.g. 9600 bps) gives quick opera-
tion. When you select an extra Low baud rate (e.g.
300 bps), then the IC-PW1/EURO needs max. 15
sec. to start the operation.
•“AUTO”baud rate;
When you want to use “AUTO”baud rate, turn the
non-“AUTO”baud rate exciter ON first, then turn the
“AUTO”baud rate exciter ON.

■Operation

17
3OPERATION
This linear amplifier has various protection circuits.
DALC circuit
The ALC (Automatic Level Control) circuit automati-
cally limits RF output power by controlling the input
level of the exciter. This prevents transmission of dis-
torted signals when the input signal level exceeds the
allowable level.
The ALC activates under the following conditions:
- Output power of the linear amplifier exceeds 1 kW
- Antenna SWR becomes 2:1 or more
- Output power of the exciter exceeds 100 W
DCooling fans
•The power supply cooling fans activate when the lin-
ear amplifier is activated and while transmitting.
•The antenna tuner cooling fans activate when the
antenna tuner is activated and while transmitting.
•All cooling fans activate when the heatsink temper-
ature of the final FETs reaches 50 °C (122 °F) or
more.
DCircuit breaker
If the circuit breaker activates or the linear amplifier
stops functioning, try to find the source of the prob-
lem, then push the circuit breaker button to fill the
white parts.
- Circuit breaker capacity: 20 A (U.S.A. version)
15 A (Europe version)
DLinear amplifier protection circuit
When a protection circuit is activated, a band indica-
tor blinks to show a problem as described below.
➥[AMP/PROTECT] lights red when a protection cir-
cuit is activated.
- Push [AMP/PROTECT] to cancel the protection circuit.
The built-in automatic antenna tuner can match the
antenna feed line impedance to 50 Ωwhen the feed
line impedance is within 16.7 to 150 Ωfor HF bands
(VSWR 3:1) or within 20 to 125 Ωfor 50 MHz bands
(VSWR 2.5:1).
Once the tuner matches an antenna, the tuning cir-
cuit condition is memorized as a preset point for each
frequency range (100 kHz steps, 70 ranges).
Therefore, when you change the frequency range,
the tuning circuit is automatically preset to the mem-
orized point.
This antenna tuner is also used when the linear
amplifier is turned OFF.
➥Push [TUNER] for 2 sec. to start manual antenna
tuning.
•When the tuner cannot tune the antenna (SWR 1.5:1 or
greater), the tuning circuit is bypassed automatically
after 20 sec.
While operating in the 50 MHz band, the antenna
tuner does not start automatically. Push [TUNER]
for 2 sec. to tune the antenna manually.
