Voltage Selection
To change the selected voltage, begin by pulling the voltage selector card straight out of the housing.
Using the indicator pin (already attached to card), orient the selector card so the desired voltage is
readable at the bottom. There are four possible selections, as shown below.
These pictures show the correct orientation of the pin for each voltage.
Orient the indicator pin to point up while the desired voltage is readable at bottom (note the pin can
be carefully rotated around the card to place it in the correct position).
The voltage card above is set to 100 V.
Insert the voltage selector card into the right-hand slot of the housing with the printed side of the card
facing forward toward the IEC connector and the edge containing the desired voltage first. Press
gently until the card is seated in the slot. Replace the cover and verify the indicator pin shows the
desired voltage.
