3. Locate a tapped hole in close proximity to the 120 VAC three position barrier terminals
(this may vary among manufactures)
4. Insert the ¼” - 20 x 1” FHP through the SPI housing and into the tap holes. Align the SPI
horizontally such that the 120 VAC wires sag below the housing and attach to the three
position barrier terminal; tighten firmly securing the SPI to the back of the housing. See
Table 2.
Note: The sag in the 120 VAC wire creates a drip loop for water to drain off the SPI housing on
to the bottom of the Pedestrian Signal Head.
Attention: Do not set the SPI on the bottom of the Pedestrian Signal Head. Failure to attach the
SPI vertically on the back surface wall can expose the power supply to water damage and will
void the warranty of the SPI
.
