A.  Position the 

P-320 

in the fixture wireway and fasten securely through the Mounting Slots. If necessary, drill holes and 

mount with sheet metal cutting screws (not provided).

B.  Fully plug the 

Quick Disconnect Harness 

into the 

P-320

 Quick Disconnect Port. Inspect that the Harness is squarely 

seated against the 

P-320

 housing.

C.  Attach the flat wire tie holder to the fixture channel. Insert a wire tie into the wire tie holder and pull the wire tie tight 

around the wires extending from the Quick Disconnect Harness.  This will help prevent the Quick Disconnect Harness 

from being disengaged. Inspect that the Quick Disconnect Harness is still fully plugged in to the 

P-320

 Port. 

A.  Locate a suitable location for the TSPL and cable that is at least 1” from the fixture lamps and is visible outside the fixture. 

Drill or punch a 1/2” diameter hole in the fixture wall or wireway cover. Insert the TSPL into the hole so that the LED test 

button/pilot light is located outside of the fixture. 

B.  Slide the TSPL Mounting Clip firmly to lock and secure the TSPL assembly.
