The Status Indicator LED indicates AC output from the power supply during LINE

operation.

Procedure:

1. Before installing the SIL-C, you will first need to remove the knockout plug

from the base of the enclosure. This can be pried out using a large flat-

blade screwdriver.

2. Route the connector-end of the SIL-C option up through the knockout hole

and into the base of the enclosure.

3. Route the large star-washer and nut over the connector and wires of the

SIL-C. Screw the nut onto the threaded portion of the lamp’s base and

tighten.

4. Connect the small 2-pin connector into its mating connector located in the

enclosure base.

5. Apply power and test the lamp for proper operation.
