Instructions for the installation, adjustment, and wiring of external controls and devices serving as required protection against
entrapment shall be provided with the operator when such controls are shipped with the operator.

Instructions regarding intended installation of the gate operator shall be supplied as part of the installation instructions or as a
separate document. The following instructions or the equivalent shall be supplied where applicable:

a) Install the gate operator only when:

1) The operator is appropriate for the construction of the gate and the usage Class of the gate,

2) All openings of a horizontal slide gate are guarded or screened from the bottom of the gate to a minimum of 4 feet (1.22
m) above the ground to prevent a 2-1/4 inch (57.2 mm) diameter sphere from passing through the openings anywhere in
the gate, and in that portion of the adjacent fence that the gate covers in the open position,

3) All exposed pinch points are eliminated or guarded, and

4) Guarding is supplied for exposed rollers.

b) The operator is intended for installation only on gates used for vehicles. Pedestrians must be supplied with a separate access
opening. The pedestrian access opening shall be designed to promote pedestrian usage. Locate the gate such that persons will
not come in contact with the vehicular gate during the entire path of travel of the vehicular gate.

c) The gate must be installed in a location so that enough clearance is supplied between the gate and adjacent structures when
opening and closing to reduce the risk of entrapment. Swinging gates shall not open into public access areas.

d) The gate must be properly installed and work freely in both directions prior to the installation of the gate operator. Do not over­tighten the operator clutch or pressure relief valve to compensate for a damaged gate.

e) (not applicable)

f) Controls intended for user activation must be located at least six feet (6’) away from any moving part of the gate and where the
user is prevented from reaching over, under, around or through the gate to operate the controls. Outdoor or easily accessible

edge, trailing edge, and postmounted both inside and outside of a vehicular horizontal slide gate.

2) One or more contact sensors shall be located at the bottom edge of a vehicular vertical lift gate.

3) One or more contact sensors shall be located at the pinch point of a vehicular vertical pivot gate.

4) A hardwired contact sensor shall be located and its wiring arranged so that the communication between the sensor and
the gate operator is not subjected to mechanical damage.

5) A wireless contact sensor such as one that transmits radio frequency (RF) signals to the gate operator for entrapment
protection functions shall be located where the transmission of the signals are not obstructed or impeded by building
structures, natural landscaping or similar obstruction. A wireless contact sensor shall function under the intended end­use conditions.

6) One or more contact sensors shall be located on the inside and outside leading edge of a swing gate. Additionally, if the
