3.1 POWER SUPPLY
The Power supply rating will be
indicated on the top of the instrument.
Ensure that this is correct for the
voltage that is to be connected. If
there is a difference, refer to Service
Manual for details of power supply
adjustment.
Note that the power supply socket has
had polarisation keys fitted to prevent
insertion into any other plug at the rear
of the instrument.
The connection is made as shown.
Ensure that no bare wire protrudes from
the rear of the power connector risking
a short circuit.
