IV. GUARDING IS SUPPLIED FOR EXPOSED ROLLERS
2) The operator is intended for installation only on gates used for vehicles.
Pedestrian must be supplied with a separate access opening.
3)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.
4) The gate MUST be properly installed and work freely in both directions prior to the installation of
the gate operator. Do not over-tighten the operator clutch or pressure relief valve to compensate for
a damaged gate. Make any necessary repairs to the gate before installing this equipment
5) The gate operator controls MUST be placed so that the user has full view of the gate area when
the gate is moving and away from the gate path perimeter.
6) Controls MUST be far enough from the gate so that the user is prevented from coming in contact
with the gate while operating the controls. Controls intended to be used to reset an operator after 2
sequential activations of the entrapment protection device or device MUST be located in the line-of-
sight of the gate. Outdoor or easily accessible controls shall have security feature to prevent
unauthorized use.
7) All warning signs and placards must be installed where visible in the area of the gate. A minimum
of two (2) placards shall be installed.
8) For gate operator utilizing a non-contact sensors ( Photo Beam or like) in accordance with section
31.1.1 of the UL 325 standards:

IMPORTANT SAFETY INSTRUCTIONS
IMPORTANT: SEA recommend to install at least 2 separate non contact sensor as on the
post close to the gate as at furthest point of the opened gate where the risk of entrapment
exists in order to avoid any risk of damage/injury (see pg. 11 Typical Installation). SEA also
recommend to install infrared Photo beam for a higher performance of use.
9) For a gate operator utilizing a contact sensor (Edge sensor or like) in accordance with section
31.1.1 of the UL 325 standards:
I. One or more contact sensors shall be located where the risk of entrapment or obstruction
exists, such as at leading edge, trailing edge, and post mounted both inside and outside of a
vehicular horizontal slide gate.
II. One or more contact sensor shall be located at the bottom edge of a vehicular vertical lift
gate.
III. One or more contact sensor shall be located at the pinch point of a vehicular vertical pivot
gate.
IV. A hardwired contact sensor shall be located and its wiring arranged so that the
communication between the sensor and the gate operator is not subject to mechanical
damage.
V. 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 end-use conditions.
VI. In case of a swing gate one or more contact sensors shall be located on the inside and
outside leading edge of the gate. Additionally, if the bottom edge of a swing gate is greater
than 6 inches (152mm) above the ground at any point in its arc of travel, one or more contact
sensors shall be located on the bottom edge (see pg..for Typical Installation)
VII. One or more contact sensors shall be located at the bottom edge of a vertical barrier (arm)
SEA warns that the gate operator system with an A.C. power electric motor shall have a
reversing sensor (encoder) on the drive shaft of the motor as additional safety device. In
case of swing linear/in-ground hydraulic operator SEA recommend to install the “SAFETY
GATE” as an additional reversing sensor.
11) The professional installer has to check that the main power supply circuit breakers are
separate, intended solely for this equipment and rated for 15 AMPS. Visually check that the circuit
breakers are in the "OFF" position and mark the circuit breakers "USED" prior to installation.
12) During service the main power MUST always being disconnected.
13) If this gate operator system includes a battery backup, the battery backup system needs to be
disconnected first, prior to disconnecting main power supply during installation, maintenance and
servicing procedures.
14) After installation The professional installer has to check that the gate operator system is
working properly, that the open and close force are properly adjusted, that the piston does not
bottom out in either direction, that breather screws have been removed, that the positive stops used
are sufficient for stopping the gate properly, and that all pinch points and potential entrapment
areas are reduced.

GROUNDING
Good grounding and proper surge suppression are an integral part of proper installation for
a gate operator system. One or all of the following may require surge suppressors: high
voltage power lines, low voltage power lines, telephone lines, data lines, low voltage control
lines and loops. How much surge suppression is required depends upon how susceptible
the area is to lightning and power surges. Regardless, good grounding is essential. To
realize maximum protection, proper grounding and proper surge suppression is absolutely
necessary.
If the circuit breaker box is located close to the gate operator system, for example, in a
guard house, then the ground from that circuit can be used to ground the gate operator
system. Eliminate all 90° bends in ground wires and keep a minimum of three feet between
the surge suppressor and the equipment being protected.
If the power source or circuit breaker box is not located close to the gate operator system an
Isolated Ground Zone (IGZ) needs to be created. An IGZ can also be created if the circuit
breaker box is located close by the gate operator system. An IGZ is an imaginary circle
drawn around the gate operator system. The gate operator system not only includes the
gate operators and control panel, but all of the accessories and devices associated with it at
that controlled entry point. This includes loop detectors, card readers, digital entries,
telephone entries, any device that has a ground or requires a ground and ali of the surge
suppressors. The ground bus is a common ground point calied a Single Point Ground
(SPG). It is used to bond all the equipment and device grounds in the IGZ together. The
SPG is very important because it helps eliminate different ground potentials that can be
present on the equipment. In such cases, equipment damage occurs even with surge
suppressors.
Do not use or connect the ground wire coming from the circuit breaker box. By using an
Isolated Ground Zone, you are separating the gate operator system from the house or
building ground. This eliminates ground potentials. It is recommended that the ground bus
be located in a separate NEMA type enclosure. All grounds will be tied to this ground bus.
Some points to remember:
Keep all ground wires as straight as possible. Do not have any sharp 90° bends. Have a
minimum of 3 feet of wire between the surge suppressor and the equipment being
protected.
Equipment ground wire should be a minimum of 12 AWG. The main ground wire from the
bus bar to the ground rod shouid be an 8 or 6 AWG copper wire. Ground rod should be a
minimum of 10 feet in length, longer depending on local soil conditions.
For more information regarding good grounding practices check: National Electric Code
art. 250; IEEE Emerald Book, standard 100; International Association of Electric
Inspectors.
IMPORTANT SAFETY INSTRUCTIONS
ALPHA
The installer is responsible for grounding the operator system,
for providing the main power breaker switch, and for making sure
that the entire gate systems meets all applicable electrical codes.
