Operation - Violectric dac v850 User Manual

THE CASE
The DAC V850's case as well as the front/rear panels are made of solid
aluminium. This choice of material ensures high mechanical stability and
resistance.
EARTH AND GROUND
The DAC V850's case is grounded. Internal reference ground is bridged
to protective earth by means of a jumper. The jumper is set to the 'LIFT'
position (see also: page 7 "Earth/Ground concept", page 25 "Technical
Appendix").
POWER SUPPLY
Mains power is provided via a three-pin IEC/CEE socket and mating
"cold-appliance" mains cord. The device is normally set to 230V mains,
whereas the actual voltage may vary between 190 and 250 volts for
flawless operation.
There are dedicated mains cords for Europe, USA, Great Britain and
China. For the USA and some other countries the unit is set to 115 V
mains ex works. Here the AC voltage may vary between 85 and 125 volt
for flawless operation. A toroidal transformer provides the internal
operating voltages.
MAINS FUSE
The 0.25A time-lag fuse is soldered in place on the circuit board. In
case, it must be replaced with a fuse of the same type only.
CAUTION !!
MIND THE SAFETY INSTRUCTIONS:
A blown fuse indicates an internal fault and
should be replaced during qualified repair or
servicing only !!
