2 Turn the perforated panel over. Slide it slightly to the right (at the rear of
the column) so it is in a secure position. Position wiring from the
perforated panel so it rests in the cable well next to the orange connector
at the rear of the module (see Figure 21). Position the perforated panel
and install the screw that secures it at the LED mounting bracket.
a Slide the LED ring over the LED (see Figure 22). The ring will hang
loosely at this point.
b Gently push the LED forward completely through the collar on the
LED mounting bracket.
