Appendix B: Voltage Selection Operation

DANGER: Disconnect Mains power before opening chassis. Voltage selector settings must not
be changed with Mains power applied to the unit.
DANGER: Wait at least ten (10) minutes after removing the power supply before performing
maintenance or an inspection. Otherwise, there is the danger of electric shock.
WARNING: The voltage selector must be configured to match the AC line voltage and is factory-
configured based on the options that you ordered. You could damage the unit if the voltage
selector is set for the incorrect AC input voltage.
The voltage selector can only be used with transformer-derived bus voltages. This voltage
selector function should not be changed when using off-line supplies. Damage to the unit may
result if this function is used improperly.
If the user changes the voltage selector settings, it is also the user's responsibility to change the
XR3 AC power label located next to the AC inlet. Refer to the
Procedure for setting AC voltage selector switches:
1. Turn-off and disconnect all power from unit.
2. Remove the four screws that secure the panel on the front of the XR3
3. Carefully remove the panel without pulling out the wiring connected to the Power Switch.
4. Use Table B-1 to set all of the voltage selector switches to the position indicated for the desired
operating voltage.
