INSTALLATION AND CONNECTIONS
■Unpacking
■AC power cable connection
After unpacking, immediately report any damage to the
delivering carrier or dealer. Keep the shipping cartons.
A suitable AC power plug must be connected to the AC
power cable end. See the diagram below for connec-
tion procedures. AC input voltage is automatically se-
lected.
For a description and a diagram of accessory equip-
ment included with the IC-PW1, see UNPACKING on
p. ii of this manual.
The IC-PW1 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 trans-
mission.
■Ferrite core installation
The supplied ferrite core and cable clips (o and ! in
UNPACKING) should be attached to the AC cable of
the IC-PW1 as illustrated below. This will help prevent
interference such as TVI, etc.
*Europe version: 230 V AC only
■Selecting a location
Select a location for the linear amplifier that allows ad-
equate air circulation, free from extreme heat, cold, or
vibrations, and away from TV sets, TV antenna ele-
ments, radios and other electro-magnetic sources.
Attach and position
the cable clips to
the AC cable as
illustrated.
Ferrite core
The linear amplifier and remote controller sections of
the IC-PW1 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.
Cut the cable clips
so that enough
length remains to
secure the ferrite
core in place.
AC cable
The linear amplifier must be placed on a solid founda-
tion since it is very heavy.
■OPC-853 AC cable with line filter
The IC-PW1 Europe version must be used with the
OPC-853 AC cable to satisfy European EMC require-
ments.
•AC power cable connection (Except Europe version)
(1) Single-phase 3-wire line (200–240 V AC)
q The green wire from the AC power cable must be
connected to the protective earth.
w The black and white wires from the AC power
cable can be connected to either terminal.
*

INSTALLATION AND CONNECTIONS
■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 be-
tween the GROUND terminal and ground as short as
possible.
R WARNING: NEVER connect the
GROUND terminal to a gas or electric pipe, since
the connection could cause an explosion or electric
shock.
■Antenna
Antenna SWR
For radio communications, the antenna is of critical im-
portance, along with output power and sensitivity. Se-
lect antenna(s), such as a well-matched 50 Ω antenna
with more than 2 kW power rating, and feedline. 1.5:1
of Voltage Standing Wave Ratio (VSWR) is recom-
mended for a desired band. Of course, the transmis-
sion line should be a coaxial cable.
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 has an SWR meter to monitor the
antenna SWR continuously.
When using 1 antenna, use the [ANT1] connector.
CAUTION: Protect your linear amplifier from light-
ning by using a lightning arrestor.

INSTALLATION AND CONNECTIONS
■System interconnections
1 or 2 Icom 100 W HF transceivers can be connected
as exciters to the IC-PW1. Non-Icom transceivers can
be used, however, band selection will not be synchro-
nized for each exciter.
See the following diagrams for making connections be-
tween the IC-PW1 and an exciter (transceiver). See p.

OPERATION
■Programming the CI-V address
The IC-PW1 uses CI-V frequency data for automatic
selection of the operating band. Program the exciter’s
address to use this capability as follows:
w Rotate the Icom exciter’s tuning dial until the
[INPUTz] light continuously lights.
e Push [POWER] to turn the IC-PW1 power OFF
and complete the setting.
For non-Icom exciters, the IC-PW1 cannot be con-
trolled using the CI-V function, so this setting is not
necessary.
DWhen using 2 exciter’s
q When using 2 Icom exciters, be sure that
[EXCITER] is set to the [1&2] position.
w While pushing [INPUT], push [POWER] to enter
the CI-V address programming mode.
- [INPUTz] blinks.
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.

OPERATION
■Antenna tuner operation
The built-in automatic antenna tuner can match the
antenna feed line impedance to 50 Ω when the feed
line impedance is within 16.7 to 150 Ω for HF bands
(VSWR 3:1) or within 20 to 125 Ω for 50 MHz bands
(VSWR 2.5:1).
This antenna tuner is also used when the linear am-
plifier 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.
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). There-
fore, when you change the frequency range, the tun-
ing circuit is automatically preset to the memorized
point.
While operating in the 50 MHz band, the antenna
tuner does not start automatically. Push [TUNER]
for 2 sec. to tune the antenna manually.
■Protection circuit
This linear amplifier has various protection circuits.
DLinear amplifier protection circuit
When a protection circuit is activated, a band indicator
blinks to show a problem as described below.
■ [AMP/PROTECT] lights red when a protection cir-
cuit is activated.
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.
- Push [AMP/PROTECT] to cancel the protection circuit.
