7. MAINTENANCE

Both the mains voltage and the high DC voltage up to 500 V inside the ACOM 2020S
amplifier are LETHAL!
For your safety, pull the amplifier power plug out of the mains wall outlet and WAIT AT
LEAST 3 minutes EACH TIME BEFORE you remove the cover of the amplifier.

Periodic Maintenance

7.1.
Periodically (but at least once per year) check all connections, contact cleanliness and the tightening of all
connectors, in particular the coaxial ones.
Check the integrity of the cables, in particular when they are laid on the floor. Check also if the cables are
secured well in the area where they come out of the connector body.
Pay particular attention to the mains plug and the wall outlet (see Sections
and
60320-C20) Power inlet
electrician.
Periodically check the SWR of the antennas and if this changes over time. Problems could occur more often
in poor weather conditions - rain, snow, strong wind etc.

Cleaning

7.2.
Do not use any solvents for cleaning. They may be dangerous to you and damage
amplifier surfaces, paint and plastic components.
Do not open the amplifier. Cleaning of the amplifier outer surfaces can be done with a piece of soft cotton
cloth lightly moistened with clean water.
Also, clean (as much as possible from the outside, without opening the amplifier) all ventilation apertures
on the front panel, rear cover and the chassis, including the ones on the top and the bottom.
Never push or put anything into holes in the case - this will cause electric shock.
