D - Line Voltage Conversion

♦You need only to lift the board out of the way, you do not need to disconnect any cables.

♦Locate the connector in front of the power transformer.

♦For 100 V, 200 V, or 208 V operation, install the plug on the connector labeled: 200 V input.

For 120 V or 230 V operation, install the plug on the connector labeled: 240 V input.

♦Replace the pc board and inner cover.

NOTE: Be sure to replace all of the screws removed in steps 9 and 11.

Close the Unit

♦Replace the outer cover.

♦Change the label on the rear panel to reflect the changed input voltage rating.

♦Reconnect the power and turn on the unit.

NOTE: Line voltage conversion does not require any fuse changes.
