Warning signs must be conspicuous. 7 Install operator inside fence line. DO NOT install operator on public side of fence line. 8 Secure gate operator cover. STEP 3: AFTER INSTALLATION 1 Test all safety features. 2 Train end user about basic functions and safety features of gate system. 3 Leave Installation and Maintenance Manual and Safety Information with end user. FOR GATE OPERATORS USING NON-CONTACT SENSOR(S) See instruction supplied with sensor for proper placement. Precautions must be taken to reduce the risk of nuisance tripping of the sensor. If there are multiple areas of risk of entrapment or obstruction, then more than one sensor should be incorporated into the system. FOR GATE OPERATORS USING CONTACT SENSOR(S) One or more sensors shall be located as shown on page 8. Care must be taken during the wiring of the sensor(s) to the operator. Make sure that the wiring cannot be damaged or interrupted. When using a sensor with a gate edge transmitter, care must be taken to insure that the RF signal is not interfered with or obstructed. SECONDARY ENTRAPMENT PROTECTION It is recommended that secondary safeties always be used for both the open and close directions. Use photo eyes, safety edges or both. In any case, the device must sense people. Loops cannot be used. Doc 01-G0665 Rev C

FOR GATE OPERATORS USING NON-CONTACT SENSOR(S)
See instruction supplied with sensor for proper placement.
Precautions must be taken to reduce the risk of nuisance tripping of the sensor.
If there are multiple areas of risk of entrapment or obstruction, then more than one sensor
should be incorporated into the system.
FOR GATE OPERATORS USING CONTACT SENSOR(S)
One or more sensors shall be located as shown on page 8.
Care must be taken during the wiring of the sensor(s) to the operator. Make sure that the
wiring cannot be damaged or interrupted.
When using a sensor with a gate edge transmitter, care must be taken to insure that the
RF signal is not interfered with or obstructed.
SECONDARY ENTRAPMENT PROTECTION
It is recommended that secondary safeties always be used for both the open and close directions.
