2.4.1 AC Wiring
The LaserLight power supply can run on either 115 or 230 VAC. The AC wiring is run through the cord grip to a
3-position AC terminal block bracket on the inside of the enclosure (shown in Figure 2-4). This bracket can be
removed by loosening the two standoffs
and lifting it off. It can then be lowered and pulled outside of the
enclosure to ease wiring connections.
Figure 2-4. Inside Enclosure Backplate Diagram
Wiring is run from the terminal block down to the power supply on the back of the mounting plate (location
shown in Figure 2-5).
Figure 2-5. Mounting Plate Diagram with CPU Board and Power Supply Locations
NOTE: Pin 1 is positioned at the left end of the connectors. See Figure 2-5 above.
Refer to the following table for AC wiring connections.
Note: Ensure that a ground wire is attached to the grounding stud located on the enclosure backplate (see Figure 2-4).
