Rewiring for 220-240V 50Hz Operation
The D/AC-l 000 canbe rewired for operationabroad. Pleaserefer this conversionto a skilled electronicstechnician to avoid personalinjury or possibleharm to the unit. Therearehigh voltages presentinside the chassisevenafter the power is turned off.
The main power supply printed circuit board hasthreeseparatepower transformers. Nearby the transformersyou will find jumper wires which correspondto the various primary windings of each power transformer.
For 120V operation, a total of six jumper wires areconnectedto the circuit board: two jumpers are
connectedneareachtransfonner, eachjumper has "120V" printed alongsideof it on the circuit
board..
For 220-240V operation,only 3 jumpers are connectedto the circuit board; onejumper is connectedneareachtransformer,eachjumper has"220V" printed alongsideof it on the circuit board.
For 220-240V operation, you must also disconnectthe six 120Vjumpers.
