3. Operation Instructions
3-1 Installation
1) Before plugging into AC outlet
The input voltage of the power supply is typically shown on the top rear part of the case. AC voltage should be within
10% of the input voltage specified, e.g., if the specified input voltage is 110V, the power supply will work with AC
voltage of 110V±10%.
Warning: The voltage indicated on the power supply (look for a sticker on the case close to the rear) must match
the AC voltage, otherwise the power supply will be damaged (plugging a power supply rated for 110V into 220V AC;
such damages are not under warranty), or the maximum output will not be reached (plugging a 220V power supply
into 110V AC). If the power supply is equipped with an AC voltage selector switch in the back, the selector switch
must show the correct value in the middle, e.g. for 120V AC, the switch itself should show 110V in the voltage
