2. With your multimeter set to DC Volts, verify that the Power Supply Output Voltage is less than 30-
VDC at TP6 (Positive lead) and TP3 (Negative Lead) as indicated in Figure 22. If the Power Supply
Output Voltage is greater than 30-VDC, then you must wait until the Power Supply Output Voltage
drops below 30-VDC before you proceed with the next step.
3. Carefully remove the input and output cables from the failed LED MODULE. (Mark the cable
connected to the LED MODULE input connector. Note: The input connector on the LED
MODULE is denoted by a black arrow pointing toward the input connector (see Figure 7).
4. Loosen and remove the nuts on the LED MODULE mounting bracket bolts. Remove the LED
MODULE bracket bolts with one hand while support the LED MODULE with your other hand.
5. Carefully remove the failed LED MODULE from the LED MODULE mounting bracket.
6. Mount the replacement LED MODULE into the mounting bracket such that the holes in the LED
MODULE heat sink are aligned with the mounting bracket holes. (Note: The replacement LED
MODULE input connector should be closest to the marked input cable connector.)
7. Push the mounting bracket bolts through the mounting bracket and the LED MODULE heat sink
holes.
8. Attach nuts to the mounting bracket bolts and tighten.
9. Gently slide the input cable connector into the replacement LED MODULE connector input housing.
10. Likewise, slide the output cable connector into the replacement LED MODULE output connector
housing.
11. The LED MODULE replacement is complete.
12. Power Supply Board must be re-calibrated after replacing an LED MODULE (see Section 10.11).
WARNING:
IMPORTANT
Power Supply Board must be re-calibrated after replacing an
LED MODULE (see Section 10.11).
