Keep the original packing for possible future transportation.
Unpack and inspect carefully the contents of the cardboard carton for possible transportation damages.
On the amplifier, check-up the chassis, front panel, display, buttons, rear panel connectors, main power
switch and fuses.
2-2.
Amplifier operating location selection; cooling.
Locate the amplifier close to the place where will be used. You will need an easy access to the rear panel
for connecting cables, and of course, to the buttons and screen on the front panel.
The ACOM 700S is forced air cooled. Locate the amplifier so that there are no objects or other devices
closer than 10cm (4”). The exhaust air can reach 65ºC (150ºF) and if the surrounding devices are
sensitive to heating from outside or use forced air cooling themselves, increase the distances accordingly.
C A U T I O N
Do not leave free paper, cloth or other light materials around
and under the amplifier. They may be drawn in by the cooling
air stream and block the vents. This will lead to overheating and
accelerated material aging, not covered by the warranty.
2-3.
Connecting the amplifier in the shack
W A R N I N G
Before you connect the amplifier to external grounding,
you should advise with a licensed electrician and confirm
such kind of connection is allowed by your national and
local electrical code, safety rules, and regulations in force.
Simultaneous connection to the earth grounding and
protective earth may be inadmissible or may fall under
special requirements in some countries!
W A R N I N G
Never use the gas installation pipes for grounding. This can
cause an EXPLOSION!
W A R N I N G
Do not use the steam-heating or water-supply network pipes
for grounding! You may expose to dangerous voltage not only
yourself but also other people using the same installation.
C A U T I O N
Bear in mind that the grounding installation may have to withstand
emergency currents over 15A with minimal voltage drop on it.
Therefore it may be necessary to improve its conductivity using
heavier leads and lower-resistance grounding path.The grounding
lead should be at least 4mm
2
(AWG 11 or SWG 13).
For details and recommendations on the grounding and RF counterpoise system concerning the
electromagnetic compatibility see also S. 3-6(f).
a) GND stud - First connect the grounding stud of the amplifier (located on the rear panel and
marked GND – Fig. 2-1) to the grounding system of the shack.
