Setting The Line Voltage - NEC LS2400 Service & Reference Manual

Setting the Line Voltage

The system contains a 260 watt power supply that is switch-selectable
for 115 or 230 VAC at an operating frequency of 50/60Hz. The power
supply voltage selection switch is factory set to 115Vac for systems
used in the United States; it is set to 230Vac for systems used in
Europe. Line source voltages between 200 and 230 VAC are acceptable
when the power supply input voltage is set to 230 VAC.
Before you plug the system power cord into an AC outlet,
ensure the input line voltage setting for the power supply is
correct.
To use the system with line source voltages between 200 and
230 VAC, the line voltage selector switch on the power supply
must be set to 230. If you set the switch to the 115 VAC
position, the power supply will be damaged when you plug in
your system.
If you need to change the line voltage setting, perform the following
steps.
Note: If you are setting up your system for the
first time, the power cord will not be connected to
the rear panel of your system.
1. Unplug the AC power cord from the back of the chassis.
2. Insert the tip of a small screwdriver or ball-point pen into the
depression on the line voltage selector.
3. Slide the selector switch to the left for 115 VAC or to the right for
230 VAC.
