INSTRUCTION MANUAL

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 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 ICPW1/EURO will be damaged.

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.

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 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 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

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.

*Use the appropriate AC plug if required.

Single-phase 2-wire line (100–120 V AC)

q The green wire from the AC power cable must be

connected to the protective earth.

w The black wire from the AC power cable must be

connected to the hot (live) wire.

e The white wire from the AC power cable must be

connected to the return wire.

Three-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 2 of 3 wires.

white black green

GND

white black green

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.

■ Grounding

To prevent electrical shock, television interference (TVI), broadcast interference (BCI) and other problems, 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.

R WARNING: 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 feedline. 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.

q Slide the coupling ring down. Strip the cable jack-

et and soft solder.

w Strip the cable as shown at left. Soft solder the

center conductor.

e Slide the connector body on and solder it.

r Screw 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 linear 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 transceivers 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 (transceiver). See p. 5 for AC power cable connection.

INSTALLATION AND CONNECTIONS

• Using 1 Icom exciter (transceiver)

CAUTION!: When connecting the supplied ACC

cable to an Icom transceiver, be sure to connect the cable to the 7-pin [ACC(2)] jack on the exciter (transceiver) side.

If the ACC cable is connected to the 8-pin [ACC(1)] jack, the protector circuit in the IC-PW1/EURO will not able to read the ALC signal. If operation continues using this setup, damage (including the possibility of explosion) to the connected transceiver and/or IC-PW1/EURO will occur.

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 supply as shown at right.

-The antenna selector functions even when the ICPW1/EURO power is OFF

In addition set the jumper on the IC-PW1/EURO controller 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.

OPERATION

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 setting is not necessary.

For transceivers which have multiple antenna connectors for speciﬁed bands (e.g. IC-726, IC-729, etc.), set the same as for 2 Icom exciters.

D Setting the Icom exciters

When connecting 2 or more CI-V devices: DO NOT use the “AUTO” baud rate for CI-V

OPERATION

■ Programming the CI-V address (continued)

D Setting 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) ICPW1/EUROs like as above left1, please set a different 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.

ï Other 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 operation. 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.

➥ Push [POWER] to turn the linear ampliﬁer ON

then turn the exciter’s power ON.

‘ Initial settings for CI-V remote control operation

OPERATION

This linear ampliﬁer has various protection circuits.

D ALC circuit

The ALC (Automatic Level Control) circuit automatically limits RF output power by controlling the input level of the exciter. This prevents transmission of distorted 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

D Cooling fans

• The power supply cooling fans activate when the linear 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 temperature of the ﬁnal FETs reaches 50 °C (122 °F) or more.

D Circuit breaker

If the circuit breaker activates or the linear ampliﬁer stops functioning, try to ﬁnd the source of the problem, then push the circuit breaker button to ﬁll the white parts.

- Circuit breaker capacity: 20 A (U.S.A. version)

15 A (Europe version)

D Linear 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.

- Push [AMP/PROTECT] to cancel the protection circuit.

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).

Once the tuner matches an antenna, the tuning circuit 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 memorized 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.

INSTALLATION NOTES

For amateur base station installations it is recommended that the forwards clearance in front of the antenna array is calculated relative to the EIRP (Effective Isotropic Radiated Power). The clearance height below the antenna array can be determined in most cases from the RF power at the antenna input terminals.

As different exposure limits have been recommended for different frequencies, a relative table shows a guideline for installation considerations.

Below 30 MHz, the recommended limits are speciﬁed in terms of V/m or A/m ﬁelds as they are likely to fall within the near-field region. Similarly, the antennas may be physically short in terms of electrical length and that the installation will require some antenna matching device which can create local, high intensity magnetic fields. Analysis of such MF installations is best considered in association with published guidance notes such as the FCC OET Bulletin 65 Edition 97-01 and its annexes relative to amateur transmitter installations. The EC recommended limits are almost identical to the FCC speciﬁed ‘uncontrolled’ limits and tables exist that show pre-calculated safe distances for different antenna types for different frequency bands. Further information can be found at http://www.arrl.org/.

• Typical amateur radio installation

Exposure distance assumes that the predominant radiation pattern is forwards and that radiation vertically downwards is at unity gain (sidelobe suppression is equal to main lobe gain). This is true of almost every gain antenna today. Exposed persons are assumed to be beneath the antenna array and have a typical height of 1.8 m.

The ﬁgures assume the worst case emission of constant carrier.

For the bands 10 MHz and higher the following power density limits have been recommended:

10–144 MHz 2 W/sq m

EIRP clearance heights by frequency band

1 Watts 2.1 m 10 Watts 2.8 m 25 Watts 3.4 m

100 Watts 5 m

1000 Watts 12 m

Forward clearance, EIRP by frequency band

100 Watts 2 m

1000 Watts 6.5 m

10,000 Watts 20 m

100,000 Watts 65 m

In all cases any possible risk depends on the transmitter being activated for long periods. (actual recommendation limits are speciﬁed as an average during 6 minutes) Normally the transmitter is not active for long periods of time. Some radio licenses will require that a timer circuit automatically cuts the transmitter after 1–2 minutes etc.

Similarly some types of emission, i.e., SSB, CW, AM etc. have a lower ‘average’ output power and the assessed risk is even lower.

Versions of the IC-PW1EURO which display the “CE” symbol on the serial number seal, comply with the essential requirements of the European Radio and Telecommunication Terminal Directive 1999/5/EC.

This warning symbol indicates that this equipment operates in non-harmonised frequency bands and/or may be subject to licensing conditions in the country of use. Be sure to check that you have the correct version of this radio or the correct programming of this radio, to comply with national licensing requirement.

NOTE: To meet European R&TTE regulations, the OPC-853 AC cable with EMC ﬁlter must be connected to the IC-PW1EURO.
