Transformer Installation - Acom 2000A Operating Manual

Normally the amplifier is supplied with Voltage Selector set for a nominal mains voltage of
240V. There might be exceptions in cases of special delivery and then the voltage set is noted
in the Table of Individual Data (Table 2-1). If your mains has a different nominal voltage, it will
be necessary for you to contact your dealer or see the TECHNICAL SUPPLEMENT for details.

2-3. Transformer Installation

After installing the transformer, the weight of the unit is about 35kg (78 lbs),
which should preferably be handled by two persons. An assistant may be
needed to hold the amplifier steady during transformer installation.
Position the amplifier, with the transformer not yet installed, flat on a table near the place where
it will be used. During the process described below, when the amplifier cover is removed, take
care not to torque or twist the chassis nor let the amplifier stand on edge. Do not lift the unit by
only one corner.
Orient the amplifier on the table so that the transformer compartment is in front of you (Fig.2-1)

Take the transformer out of the carton and remove the shipping board but do not discard the
shipping board or the bolts. For transformer mounting, four shorter bolts (M8x16mm) are
provided in a polyethylene envelope inside the same carton. Use the polyethylene envelope to
store the longer shipping bolts. Keep the board together with the four long bolts and all packing
for possible future transportation of the transformer.
