SAFETY INSTALLATION INFORMATION
SAFETY INSTALLATION INFORMATION
1. Vehicular gate systems provide convenience and security. Gate systems are
comprised of many component parts. The gate operator is only one
component. Each gate system is specifically designed for an individual
application.
2. Gate operating system designers, installers and users must take into account
the possible hazards associated with each individual application. Improperly
designed, installed or maintained systems can create risks for the user as
well as the bystander. Gate systems design and installation must reduce
public exposure to potential hazards.
3. A gate operator can create high levels of force in its function as a component
part of a gate system. Therefore, safety features must be incorporated into
every design. Specific safety features include:
• Gate Edges • Guards for Exposed Rollers
• Photoelectric Sensors • Screen Mesh
• Vertical Posts • Instructional and Precautionary Signage
4. Install the gate operator only when:
a. The operator is appropriate for the construction and the usage class of the
gate.
b. All openings of a horizontal slide gate are guarded or screened from the
bottom of the gate to a minimum of 4 feet (1.2 m) above the ground to
prevent a 2-1/4 inches (6 cm) 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.
c. All exposed pinch points are eliminated or guarded, and guarding is
supplied for exposed rollers.
5. 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.
6. 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.
7. The gate must be properly installed and work freely in both directions prior
to the installation of the gate operator.
8. Controls intended for user activation must be located at least 6 feet (1.8 m)
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 controls shall have a security feature to
prevent unauthorized use.
9. The Stop and/or Reset (if provided separately) must be located in the
line-of-sight of the gate. Activation of the reset control shall not cause the
operator to start.
10. A minimum of two (2) WARNING SIGNS shall be installed, one on each side
of the gate where easily visible.
11. For a gate operator utilizing a non-contact sensor:
a. Reference owner’s manual regarding placement of non-contact sensor for
each type of application.
b. Care shall be exercised to reduce the risk of nuisance tripping, such as
when a vehicle trips the sensor while the gate is still moving.
c. One or more non-contact sensors shall be located where the risk of
entrapment or obstruction exists, such as the perimeter reachable by a
moving gate or barrier.
12. For a gate operator utilizing a contact sensor such as an edge sensor:
a. One or more contact sensors shall be located where the risk of
entrapment or obstruction exists, such as at the leading edge, trailing
edge and post mounted both inside and outside of a vehicular horizontal
slide gate.
b. One or more contact sensors shall be located at the bottom edge of a
vehicular vertical lift gate.
c. A hard wired contact sensor shall be located and its wiring arranged so
the communication between the sensor and the gate operator is not
subject to mechanical damage.
d. A wireless contact sensor such as the 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 end-use
conditions.
e. One or more contact sensors shall be located on the inside and outside
leading edge of a swing gate. Additionally, if the bottom edge of a swing
gate is greater than 6 inches (152 mm) above the ground at any point in
its arc of travel, one or more contact sensors shall be located on the
bottom edge.
f. One or more contact sensors shall be located at the bottom edge of a
3

SAFETY
REQUIRED ENTRAPMENT PROTECTION DEVICES
REQUIRED ENTRAPMENT PROTECTION DEVICES
To prevent SERIOUS INJURY or DEATH from a moving gate:
• Entrapment protection devices MUST be installed to protect anyone who may
come near a moving gate.
• Locate entrapment protection devices to protect in BOTH the open and close
gate cycles.
An entrapment zone is every location or point of contact where a person can become entrapped between a moving gate and a stationary object. All gate operator systems
REQUIRE two independent entrapment protection systems for each entrapment zone. This operator contains an inherent (internal) entrapment protection system (the primary
entrapment protection system) and REQUIRES the addition of an external entrapment protection system (non-contact photoelectric sensor or contact safety edge sensor) for
EACH entrapment zone.
Your application may contain one or many entrapment zones. Property owners are obligated to test entrapment protection devices monthly.
CONTACT SENSORS (EDGE SENSORS)
If the electrically activated edge sensor comes in contact with an obstruction while the gate is moving, the gate will stop and reverse. The gate will not be able to travel in that
direction until the obstruction is cleared. Use edge sensor models G65MG0204, G65MGR020, or G65MGS020.
• Locate entrapment protection devices to protect between moving gate and
RIGID objects, such as posts or walls.

If the photoelectric sensor beam gets blocked while the gate is moving, the gate will stop and reverse. The gate will not be able to travel in that direction until the obstruction
is cleared. It is best to use monitored photoelectric sensors, model CPS-UN4. If a monitored photoelectric sensor is not working or loses power or the beam is blocked, then ALL
gate operation in that direction will stop. Unmonitored photoelectric sensor models AOMRON and RETROAB are also acceptable.

IMPORTANT SAFETY INFORMATION
INSTALLATION
To prevent SERIOUS INJURY or DEATH from a moving gate:
• Pinch points must be guarded at all times. Install enclosed-style gate tracks and
roller guards.
• Place screen mesh 4 feet (1.2 m) high on the gate to prevent access through
openings anywhere the gate may travel.
• Mount controls at least 6 feet (1.8 m) from the gate or ANY moving part of the
gate.
• Install Warning signs on EACH side of gate in PLAIN VIEW. Permanently secure
each Warning sign in a suitable manner using fastening holes.
• This operator is intended for vehicular use only. To prevent INJURY to
pedestrians, a separate pedestrian access should be supplied, visible from the
gate. Locate the pedestrian access where there is not a chance of INJURY at any
point during full movement of the gate.
• Contact sensors MUST be located at the leading and trailing edges, and post
mounted both inside and outside a horizontal slide gate. Non-contact sensors
such as photo eyes MUST be mounted across the gate opening and operate
during BOTH the open and close cycles.
IMPORTANT SAFETY INFORMATION
• Entrapment protection devices MUST be installed to protect anyone who may
come near a moving gate.
• Locate entrapment protection devices to protect in BOTH the open and close
gate cycles.
• Locate entrapment protection devices to protect between moving gate and RIGID
objects, such as posts or walls.
• Too much force on gate will interfere with proper operation of safety reversal
system.
• NEVER increase force beyond minimum amount required to move gate.
• NEVER use force adjustments to compensate for a binding or sticking gate.
• If one control (force or travel limits) is adjusted, the other control may also
need adjustment.
• After ANY adjustments are made, the safety reversal system MUST be tested.
Gate MUST reverse on contact with a rigid object.
• DO NOT touch the heater when switch is on, heater may be hot.
• To AVOID damaging gas, power or other underground utility lines, contact
underground utility locating companies BEFORE digging more than 18 inches

WIRING
To reduce the risk of SEVERE INJURY or DEATH:
• ANY maintenance to the operator or in the area near the operator MUST NOT
be performed until disconnecting the electrical power (AC or solar and battery)
and locking-out the power via the operator power switch. Upon completion of
maintenance the area MUST be cleared and secured, at that time the unit may
be returned to service.
• Disconnect power at the fuse box BEFORE proceeding. Operator MUST be
properly grounded and connected in accordance with national and local
electrical codes. NOTE:The operator should be on a separate fused line of
adequate capacity.
ADJUSTMENT
To reduce the risk of SEVERE INJURY or DEATH:
• Without a properly installed safety reversal system, persons (particularly small
children) could be SERIOUSLY INJURED or KILLED by a moving gate.
• Too much force on gate will interfere with proper operation of safety reversal
system.
• NEVER increase force beyond minimum amount required to move gate.
• ALWAYS wear protective gloves and eye protection when changing the battery
or working around the battery compartment.

INTRODUCTION
OPERATOR SPECIFICATIONS
This model is intended for use in vehicular slide gate applications:
Check the national and local building codes BEFORE installation.
GATE
Gate must be constructed and installed according to ASTM F2200 standards (refer to page 4). Gate must fit specifications of operator (refer to specifications).
SAFETY CATCH ROLLERS
Install catch rollers with safety covers
on the side of a post or wall with a
minimal distance of half an inch
between the rollers and gate.
10
DO NOT use a gate catch post.
Because the coasting distance may vary due to
changes in temperature, it is NOT recommended
to install a stop or catch post in front of the
gate's path. To do so will cause the gate to hit
the post in certain instances.
SITE PREPARATION
CONDUIT & CONCRETE PAD
Conduit must be UL approved for low and high voltage. Consider the operator
placement BEFORE installing the pad or post.
Concrete Pads
SAFETY
Entrapment protection devices are required to protect against any entrapment
or safety conditions encountered in your gate application (refer to page 5 for
more details). Install warning signs on both sides of the gate.
EARTH GROUND ROD
Proper grounding gives an electrical
charge, such as from an electrical static
discharge or a near lightning strike, a
path from which to dissipate its energy
safely into the earth. Without this path,
the intense energy generated by
lightning could be directed towards the
gate operator. Although nothing can
absorb the tremendous power of a direct
lightning strike, proper grounding can
protect the gate operator in most cases.
