Safety Edge and Warning Placard Installation 
See reversing edge sensor instructions for the exact placement of the reversing edge contact sensors.
One or more safety edge contact sensors shall be located at the leading edge, trailing edge, and post mounted both inside and outside of a vehicular horizontal slide gate. When the contact sensor is hard wired, it shall be located and its wiring arranged so that the communication between the sensor and the gate operator is not subjected to mechanical damage.
With full systems capability control boards, the edge sensor is connected to terminals 24 and 26 as shown at left in figure 2.
The gate operator is provided with two safety warning placards. The placards are to be installed on each side of the gate where they are plainly visible. The placards may be mounted using sheet metal screws through the six holes provided on each placard.
All warning signs and placards must be installed where visible in the area of the gate.
