Operation PHONE-AMP G109
EARTH AND GROUND
The Case of PHONE-AMP G109 is connected to earth potential. The internal
ground potential is set to "LIFT" position but may be connected to earth by
means of a jumper. If required, the jumper may be set to "GND" position (see
page 16: "The earth/grounding concept" and page 26: "Jumper settings").
THE POWER SUPPLY
Mains is connected via a three-pin IEC/CEE socket and a matching three-wire
mains cable with Schuko-type mains connector.
The unit is factory-set to a mains voltage of 230 VAC and may be set to 115 Volt
operation internally.
Mains voltage may vary between 190 and 250 (85 ... 125V) without any effect
on flawless operation.
The built-in toroidal mains transformer provides the internal supply voltages of
+/- 30 Volt.
SETTING TO 115 V AC
When G109 is purchased to 115 Volt countries (USA, Japan, Taiwan) normally it
is set to 115 Volt operation before shipping.
This is marked by 115 Volt sticker on the back of the unit.
Please note that the operation of 230 V equipment in a 115 V environment is
NOT dangerous at all. Under most circumstances the unit will refuse to work
properly.
When this amp is set to 115 V AC operation but is accidentally plugged to a 230
power outlet the internal fuse will be blown immediately !!
THE MAINS FUSE
The 0,25 AT fuse is internally soldered in place on the power supply PCB.
ATTENTION !!
FOLLOW THE SAFETY INSTRUCTIONS:
A blown fuse may refer to internal problems and should only been replaced
during qualified servicing works !!
