Installation Of Optional Fan; Power On, Rcu Controls, Indicators And Menus - Acom 2000A Operating Manual

Before connecting the amplifier to your mains supply, be sure that the
supply is correctly wired, and is adequate for the current drawn by the
amplifier. Make certain that the grounding lead is connected properly in
the wall outlet for the amplifier.
It is preferable that you use the wall outlet closest to the source. The installation leads should
be at least 2.5mm (AWG 12 or SWG 15). Check if the respective fuses can handle current up
2
to 20A, as well as if the voltage corresponds to the voltage for which the amplifier is set (S.2-2).
If you connect the amplifier to a different mains outlet, be sure that you check it, too.
Make sure the main Power Switch on the front panel is in OFF position (so that the red strip on
the switch is hidden) and insert amplifier's mains plug into the wall outlet prepared for it. The
amplifier remains switched off.

2-5. Installation of Optional Fan

This fan 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 the fan is recommended. The auxiliary fan (119x119mm) is supplied as an option
with a set of 8 screws, nuts and washers. It may be mounted by the manufacturer or dealer
on request (Fig. 2-2). Contact your dealer or see the TECHNICAL SUPPLEMENT for details.

3. POWER ON, RCU CONTROLS, INDICATORS AND MENUS

Before you turn the amplifier on, at least 2 hours should have expired since
it was brought in and unpacked in the room where it will be used. Pay
particular attention when you move it from a very cold into a very 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).
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 on the front
panel. The red LED indicator above it must light and a picture will appear on the RCU (Fig.3-
1):
