GROUND AND PROTECTIVE EARTH
The case of
VIOLECTRIC DHA V226
is connected to protective earth.
POWER SUPPLY
Mains power is provided via a three-pin IEC/CEE socket and mating
"cold-appliance" mains cord with Schuko-type plug for units
purchased in middle Europe.
The device is set to 230V mains, whereas the actual voltage may
vary between 190 and 240 volts for flawless operation.
The mains voltage may be altered to 115 V AC supply inside the unit
with the aid of a mains voltage selector. In this case stable operation
is granted in a range of 85 to 120 V (see page 30).
A toroidal transformer with 15 Watt is providing the internal
operating voltages of +/-25 V. Out of these voltages some more
operating voltages are generated.
MAINS FUSE
The 0.5A 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.
