Before connecting to a mains electricity supply, check that the MS2WFP power supply is set to
the required AC supply voltage. The voltage selection is performed using the voltage selector
switch, which is mounted on the bottom left hand side of the rear panel of the power supply
unit. This is shown in Figure 26. The selected voltage should be displayed on a label positioned
by the power inlet socket. To alter the supply voltage, proceed as described in the figure, always
remembering to record the new voltage on the label.
