Getting Started With The Acom 04At; Turning On And Off - Acom 04AT Operating Manual

Lay out the cables in the necessary directions and attach them to the provided holes
in the supporting bracket. Finally, fasten the rings of the coaxial connectors so that
swinging and vibrations from the wind will not loosen them. If you need additional
binding points besides the holes in the supporting bracket, affix the cables further, e.g.
up the mast or to other surrounding objects and walls. Use only UV-resistant materials!
Always leave a sufficient U-shaped slack in the cabling be-
low the tuner's bottom level, so that any water would dripoff
and not enter the tuner.
c) Connect the RF coax from the radio station to the tuner socket labeled "50 Ohm RF
+26VDC Power & Control" in a similar way. If the distance to the radio station exceeds
30m (100ft), we recommend using a RG-213 type, an equivalent or a better cable. Lay
out and attach the input cable and fasten the connector ring.

3. GETTING STARTED WITH THE ACOM 04AT

3.1 TURNING ON AND OFF

After you complete the tuner installation instructions, verify that the amplifier master
power ON/OFF switch on the back panel is in the OFF position, and the plug is pulled
out of the mains socket.
Before connecting the coaxial cable from the tuner to the
amplifier output, make sure that the cable and amplifier are
securely grounded to the grounding system of the radio
station. Using a voltmeter, check the cable coming from the
tuner to verify there is no AC or DC voltage above 12V from
the pin and the ring of the cable connector to the grounding
terminal of the amplifier and between the connector pin and
ring!
Connect the tuner coaxial cable to the RF OUTPUT of the amplifier. Besides RF power,
the tuner will be supplied with DC power from the amplifier (+26V DC with consumption
up to 25 W), and bidirectional control data (60kHz FSK), all combined on the same
cable.
