1. Position the jumpers for the desired XLR pin-out on PL
233/234 as shown in Figure 2-5.
2. Position the jumper on PL 121 for the desired boot setting
as shown in Figure 2-5. The hard boot setting is only used
to upload software when the fixture must be set to boot
mode and the control panel does not function. After the
upload, move the jumper back to the normal setting.

1. Arrange the circuit board and lamp relay wires neatly in the base.
2. Fasten the transformer wires to the back rail with a wire tie.
3. Position the pan assembly in the base.
4. Fasten the assembly with 6 x 10 mm bolts and lock nuts.
5. Install the AC filter on the pan assembly with the "load" end towards the ballast.
6. Connect the AC filter wires. On the line side, connect the neutral (blue) wire to the top terminal, the live (brown)
wire to the bottom terminal, and ground wire to the case. Similarly, on the load side, connect the blue wire lead-
ing to the capacitor to the top terminal and connect the brown wire to the bottom terminal.
7. Plug in the pan sensor and motor wires.
8. Plug the pan-reset switch wires into the bottom 2 switch contacts.
