Selecting the Voltage
Refer to the table immediately above the selector switches or consult
the following table and set the switches as required. For example, if
the accessory is connected to 240 volts, the table tells you that the
switch setting should be ‘AD’. This means the left switch should be
up (position ‘A’) and the right switch should be down (position ‘D’).
