Grounding
For protective earthing, plug the power cord into a properly grounded outlet.
How To Set the Line Voltage
The line voltage selector, located on the rear panel of the 651 unit (refer to Figure 9), configures
the 651 unit to accept either 115 or 230 VAC input voltage
Caution
The Line Voltage Selector on the 651 unit must be set to the proper
input voltage
before
you connect the power cord and turn on the
power. Otherwise, the unit will be severely damaged.
Note
Be sure to install the correct fuses for the line voltage selected.
To change the line voltage:
1. Be sure that the power cord and all interface cables are disconnected from the 651
controller.
2. Use a blunt instrument, such as a flat head screwdriver, to slide the line voltage selector
switch to the left position for operation in the 115 V range, or to the right position for
operation in the 230 V range.
Refer to Figure 3. The value of the selected line voltage is visible through the window
in the cover of the switch. The voltage and fuse label above the switch shows the
corresponding voltage range and fuse requirements for either voltage setting.
