Position backplate on pole at correct height and orientation so arrow points to ending of crosswalk on the opposite side of
the street. Orientation is very important because a blind person uses the arrow and face of the sign to orient themselves
to the direction of travel. Mark mounting bolt locations if existing holes not correctly located. MUTCD max. height is 48”.
Typical recommended height is 42”, but can be lower. Drill and tap ¼-20 bolt holes and wire access hole (if necessary).
Position the backplate against the pole and route the wires forward near the bottom end of the backplate. Position the wire
such that 3 or 4 inches of wire is available at the bottom of the backplate.
Attach the backplate to the pole using the provided ¼-20 bolts with washers.
Re-install the electronics/speaker modules. Re-install the sign (and sign backplate if using), securing the PBS Module in
place before wiring. Re-install EARTH GND (ground) connection screw to location between terminal blocks.
Connect the two wires from the traffic signal cabinet to the terminals of the larger black terminal block labeled
BUTTON/PLC. Wire polarity is not important. Recheck tightness of all connections.
