Power Supply Modification:
For nominal voltages of 100, 110, 115 and 230 Vac terminals 7 and 9 are used.
The changeover between the range of 100 to 115 Vac and 230 Vac is carried out via switch
S1. The latter is located on the printed circuit board in such a way that it is easily accessible.
Its two switch positions are marked with "115 V" and accordingly "230 V". The default setting
is "115 V".
For nominal voltages of 120 and 125 Vac the connection terminals 7 and 11 are used. The
switch S1 is put into position "115 V"
Any change in the default setting of the auxiliary voltage matching of 100...125 Vac may be
indicated on the label of the front panel of the device making a cross on the corresponding
voltage value
