voltage (see section ”Replacing the
fuses” in this chapter).
• Close the cover (1). The selected voltage
is shown in the cover window.
Note
– In many countries where the nominal
mains power voltage is 230 V, the actual
voltage is found to vary within a higher
voltage range than specified for the selector
setting 220 V. In such case, the selector
setting for 240 V is recommended.
