2 INSTALLATION AND CONNECTIONS ■ Linear amplifier connections D Connecting the IC-PW1/EURO ACC-1 To an antenna ANT ACC cable (supplied with the IC-PW1/EURO) Remote control cable (supplied with the IC-PW1/EURO) REMOTE Coaxial cable (supplied with the IC-PW1/EURO) INPUT1 INPUT2 Be sure to connect the cable to the 7-pin ACC 2 jack. Connect [INPUT2] if necessary Coaxial cable* REMOTE EXCITER 1 1&2 GND ANT1 ANT2 GND ACC 2 IC-PW1/EURO AC outlet Ground (Non-European versions: 100-120/220-240 V European version : 230 V) Transceiver *Optional D Connecting a non-Icom linear amplifier To an antenna ANT1 50 Ω RELAY coaxial cable Transceiver ALC RF OUTPUT RF INPUT SEND ALC Non-Icom linear amplifier R WARNING: Set the transceiver output power and linear amplifier ALC output level after referring to the linear amplifier instruction manual. The ALC input level must be in the range 0 V to -4 V. The transceiver does not accept positive voltage. Non-matched ALC and RF power settings could overheat or damage the linear amplifier. The maximum signal level of [RELAY] jack is 16 V/0.5 A DC with initial setting, and 250 V/200 mA with "MOSFET" setting (see p. 12-8 for details). Use an external relay unit if your non-Icom linear amplifier requires control voltage and/or current greater than specified. 2-8
