4. Remove the AC-voltage selection wheel from the unit.
Do not attempt to rotate the wheel while it is still in the power

for proper operation.
5. Re-insert the wheel into the module so the desired AC voltage can
be viewed in the power-module window.
6. Ensure the proper fuses are installed in your system.
The power entry module requires two 5x20-mm slow-blow fuses,
such as Littelfuse’s
