2.4.1 Mains voltage selector
The mains voltage selector is a small drawer placed in the mains input / main switch module. The user can
select the regional input voltage range (110–120 V or 220–240 V) by pulling out the selector (using a small
screwdriver) and turning it. The selected voltage range is marked by the small arrow on the module that points
to the white mark at the input connector assembly.
