Electrical Input Requirements
The TW6900 is equipped with an input voltage jumper block so the unit can be operated with
different line voltages depending on the supplied voltage. The jumper setting should be checked
to see if they are properly positioned for the voltage being used.
Remove the TW6900 top cover
Cross the terminals on the jumper block with the jumper and tighten the hold down nuts
Use the schematic below for the jumper setting to suit the line voltage requirements
