Power Outlets Check
CAUTION
Incorrect voltage may damage the machine. The machine must
not be connected to the power outlet if the voltage is incorrect.
The following steps check the input voltage:
1 Check the machine identification plate to confirm the
machine voltage.
2 Check the supply voltage by performing one of the
following checks:
• Go to US and XCI 114VAC
• Go to European Union 230VAC
• Go to Europe 220VAC
US and XCI 115VAC
US and XCI 115 VAC, Figure 1. Measure the AC voltage
between AC line and neutral and between AC neutral and GND.
The voltage between line and neutral is 104 to 127 VAC and the
voltage between neutral and GND is less than 3 VAC.

European Union 230 VAC
European Union 230 VAC ± 10%, Figure 2. Measure the AC
voltage between AC line and neutral and between AC neutral
and earth/GND. The voltage between line and neutral is 207 to
253 VAC and the voltage between neutral and GND is less than
3 VAC.

Europe 220 VAC
Europe 220 VAC, Figure 3. Measure the AC voltage between the
supply pins, then between a supply pin and earth and then
between the other supply pin and earth. The voltage is 196 to
244 VAC between the supply pins and between one of the
supply pins and earth. Between the other supply pin and earth,
the voltage is less than 3 VAC.

If the supply voltages are incorrect, or the wiring of the main
supply is found to be defective, inform your technical manager.
