3.1 Configuring the Unity Gain Combiner for 220 to 240 VAC Operation

The Unity Gain Combiner is factory set for 120 VAC operation, with "115V" showing as the
voltage setting in the power inlet module window (Figure 4). To configure the unit for 220 to
240 VAC operation, perform the following:
Note: The Unity Gain Combiner is supplied with a detachable power cord for 120 VAC
operation. For 240 VAC operation, consult your local electrical code for the correct type
or style of power cords required.
1. Make sure the power cord is removed from the power inlet module before continuing.
2. Pry open the power inlet module door from the right side using a small screwdriver or
equivalent.
3. Remove the fuse module using a small screwdriver or equivalent.
4. Rotate the fuse module 180° so that the text "230V" will show through the power inlet
module window when the door is closed.
5. Place the fuse module back into the power inlet module, making sure that the fuse
module is seated properly.
6. Close the power inlet module door, making sure that it snaps firmly into place, and that
"230V" does show through the window.
7. Connect the correct type of power cord corresponding to the local electrical code.
8. Ensure that the Power LED is lit (GREEN), indicating that the unit is receiving power.
