7.3 Changing AC Power Supply Voltage
Follow the steps below to switch the AC power supply voltage
1.Turn off and disconnect the power cord and input/output cable from the amplifier unit
2.Remove the cover using two screws (M3) on the top face (Fig.7-6).
3.The AC power supply selection switch is positioned at the location shown in Fig.7-7. Selection
to 200 VAC, OFF, and 100 VAC is available. Voltage switching is available by sliding the switch
to the target voltage position. The fuse can support both 100 VAC and 200 VAC. The installed
fuse (100 VAC/200 VAC, 100 mA: 0334-3006) can therefore be used for both supply voltages.
4.Attach the amplifier cover so that the slit of the amplifier cover matches to the frame of the
amplifier unit.
5.Fasten the screws of upper face.
6.When using 200 VAC power supply, use optional AC power cord 200 V (Fig.7-8: 0311-5112).

-Power cord and input/output cable should be disconnected.
-As the AC power cord 200 V (0311-5112) has bare wire at one end,
processing is needed to connect to the power source.
-After switching the power supply voltage, change the power supply voltage
rating indicated on the plate on the amplifier cover.
