3.4 220 to 240 VAC Operation
The Redundant Amplifier Switch is factory set for –48 VDC or 120 VAC operation, with
“115V” showing as the voltage setting in the power inlet module window (
Figure 11
). For 220
to 240 VAC operations, do the following:
Note:
The Redundant Amplifier Switch is supplied with three detachable power cords
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. GREEN front panel LEDs should be lit (refer to
) indicating that the internal
power supply is operational, and that there are no errors.
