Connections - Acom 2000R Operating Manual

Move the transformer, using its rope sling handle, into the compartment. Take care not to damage the
wiring or components and position the transformer so that the captive nuts are aligned with the
corresponding chassis holes. Make sure that the transformer is centered. The transformer bolts must
be installed NOW for safe operation.
Holding its two sides (front and back) simultaneously, pull the amplifier towards you just far enough that
the two outside transformer captive nuts appear off the table edge. Support the amplifier until your
assistant loosely screws in the two outside transformer-mounting bolts. Pull the amplifier a further
12-13cm (about 5 inches) until the other two captive nuts appear off the table edge. Keep supporting
the amplifier until your assistant loosely screws them in. After checking that the transformer is centered,
tighten all 4 bolts. Now move the amplifier back over the table.
The transformer's Mains Connector plugs into the AC power console (Fig.2-1). The other three
connectors (HV, Motors Voltage & SG Voltage) plug into the HIGH VOLTAGE PCB, clearly seen on top.
Replace the cover and carefully reinstall all screws.

2-4. Connections

The amplifier is now ready to be connected to your station. Connection must be accomplished in the
order described below, before you apply mains voltage to the amplifier.
Have in mind that the grounding system may have to withstand currents
over 20A with insignificant voltage drop on it. Therefore it may be necessary
to improve it considerably (to become lower-resistive, i.e. with heavier leads
and lower-resistive ground path). The grounding leads should be at least
8mm (AWG 8 or SWG 10).
