INSTRUCTION MANUAL
HF/50 MHz ALL BAND
1 kW LINEAR AMPLIFIER
iPW1
iPW1EURO
IMPORTANT
READ THIS INSTRUCTION MANUAL CAREFULLY before attempting to operate the linear amplifier.
SAVE THIS INSTRUCTION MANUAL. This instruction manual contains important safety and operating instructions for the IC-PW1/IC-PW1EURO.
PRECAUTION
RWARNING HIGH VOLTAGE! NEVER attach an antenna or internal antenna connector during 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 amplifier may result in an electrical shock.
RNEVER apply AC voltage that exceeds the suggested 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 controller to rain, snow or any liquids.
NEVER allow children to play with the linear amplifier 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 ICPW1/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 compass to prevent erroneous indications.
The IC-PW1/EURO cannot be used with the AH-2 HF AUTOMATIC ANTENNA TUNER.
For U.S.A. only
CAUTION: Changes or modifications to this device, not expressly approved by Icom Inc., could void your authority to operate this device under FCC regulations.

2 INSTALLATION 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 equipment included with the IC-PW1/EURO, see SUPPLIED ACCESSORIES on p. ii of this manual.
■Ferrite core installation
The supplied cable ties (o in SUPPLIED ACCESSORIES) should be attached to the AC cable of the IC-PW1/EURO as illustrated below.
Attach and position the cable ties to the AC cable 
as illustrated.
Ferrite core
Cut the cable ties so that enough
AC cable length remains to secure the ferrite
core in place.
■AC power cable connection
A suitable AC power plug must be connected to the AC power cable end. See the diagram below for connection 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
DSingle-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.
*
white black green
NOTE: Only one ferrite core is attached with the ICPW1EURO.
■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 elements, 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 foundation since it is very heavy.
DSingle-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.
white black green
GND
DThree-phase 3-wire line (200–240 V AC)

wThe black and white wires from the AC power cable can be connected to 2 of 3 wires.
