Acom 700S - 1. GENERAL INFORMATION; 1.1. Introduction and Description

9
If your transceiver has a suitable input, that disables transmission unless grounded externally, we
recommend this to be connected to the KEY-OUT jack of the amplier. Use shielded cable terminated
with а standard RCA (PHONO) plug.
The transceiver manufacturers give di󰀨erent names to this input, for example: TX-INHIBIT, MUTE,
LINEAR, and others. Check the manual of your transceiver. Approach your dealer for details. If your
transceiver has no such input, do not worry – ACOM 700S will operate normally with KEY-OUT
unconnected.
d) RF INPUT - Connect a coaxial cable with a PL-259 plug from the transceiver output
(antenna jack) to the amplier RF INPUT jack.
C A U T I O N
In order to avoid a damage, turn o󰀨 your transceiver’s internal antenna tuner.
e) RF OUTPUT - Connect a suitable coaxial cable with a PL-259 plug from the RF OUTPUT
on the rear amplier panel to the antenna switch, tuner or antenna intended for the
respective frequency band.

If you use an amplier for the rst time in your shack, pay serious
attention to the size of coaxial cable from your amplier output
to the antenna. The cable must be capable of handling the
increased power safely, particularly on the 10m and 6m bands.
This warning applies equally to the antenna switch, tuner, and
the whole antenna system, especially multi-band trap antennas.
We recommend using RG213 or better. Consult your local coax cable supplier.
f) Preparation of the mains outlet for the amplier, requirements for the installation and
the mains voltage.
C A U T I O N
Before connecting your amplier to the power grid, be sure
that the outlet is correctly wired and is capable of providing the
required current i.e. (up to 10A from 200/240VAC mains and up to
16A from 100/120VAC mains). Also make sure that the grounding
lead is connected properly in the outlet, intended for the amplier.
If subsequently you connect the amplier to a di󰀨erent outlet,
check it as well.
It is preferable to use the mains outlet closest to the source. Make sure that the respective fuses and
voltage of your power mains match the ACOM 700S amplier’s specications (see S. 8-1(g)).
g) Main fuses.
C A U T I O N
Make sure you check whether the main fuses installed in
your amplier correspond to your local mains nominal voltage
and if necessary replace them as described in Section 7-2!
h) Power cord. Due to di󰀨erent standards in di󰀨erent countries, the ACOM 700S is
delivered without a power plug for the mains cable. You dealer might be able to provide
the correct Safety Class I plug. The ground lead of the power cable is colored yellow
with two green stripes. If you have any doubts about the correct way to connect these
wires, consult your dealer..
