Make sure the main Power Switch on the rear panel is in OFF position and insert amplifier's
mains plug into the wall outlet prepared for it. The amplifier remains switched off.
2-5. Installation of External Fan
This fan (Fig. 2-1) is not necessary in SSB and CW modes, nor in continuous carrier modes
(RTTY, SSTV etc.) with carrier down times of maximum 15 minutes and a subsequent pause
of 3 minutes. For higher duties or increased ambient temperatures the fan is recommended.
The auxiliary fan (92x92x25mm or 92x92x38mm) must be brushless type, 2...5W/24VDC. It
may be installed by your dealer or by the manufacturer on request.
3. POWER ON, CONTROLS AND INDICATORS
C A U T I O N
Do not turn the amplifier on for at least 2 hours after unpacking it in the
room where it will be used. Pay particular attention when you move it
from a very cold into a warm place - condensation is likely and this
could result in damage to the high voltage circuits. In such a case, wait
at least 4 hours. A similar effect can occur after a rapid warming of the
operating room (for instance after switching on a powerful heater in a
cold shack).
C A U T I O N
To avoid damage (not covered under warranty) carefully check that the
voltage for which the amplifier is set corresponds to your mains nominal
voltage (see S.2- 2 and table 2-1).
After following all instructions in S.2, you can turn ON the main power switch marked "LINE"
on the rear panel (Fig.2-1). The LED indicator above the red ON/OFF button located on the
front panel must light red and a black inscription "ACOMI500" will appear on the display
(Fig.3-1):
