SAFETY SUMMARY
It is imperative that everyone involved in the installation or operation of the gate operator read the
following warnings.
WARNING!
1. READ AND FOLLOW ALL INSTRUCTIONS. Improper installation of a gate operator
can result in a dangerous system. SAVE THESE INSTRUCTIONS.
2. A vehicle gate is a large, heavy object that is moved by an electric motor. A moving
gate can cause serious injury or death! The safety and well-being of others depends
on the installation of a safe system.
3. The entrance is for VEHICLES ONLY. Pedestrians must use a separate entrance.
Always keep people and objects away from the gate. NO ONE SHOULD CROSS THE
PATH OF THE MOVING GATE.
4. Choose one or more controls that together will allow complete control of the gate.
Most importantly, the gate must be able to be stopped at all times in case of
emergency, and the emergency control should be conveniently located, clearly
marked and visible.
5. All controls must be kept out of the reach of small children. Serious injury or death
can result from children playing with the controls.
6. All controls should be located so the person operating them can see the full area of
gate movement.
7. Use the emergency release only when the gate is not moving.
8. KEEP GATES PROPERLY MAINTAINED. Have a qualified person make repairs to the
gate hardware.
•Test the gate operator safety features monthly. The gate MUST reverse on contact
with a rigid object or stop when an object activates the non-contact sensors.
•After adjusting the force or the limit of travel, retest the gate operator. Failure to
adjust and retest the gate operator properly can increase the risk of damage, injury
or death.
9. Gate operators and associated control equipment should be installed by qualified
professional installers who should observe the following safe installation procedures:
•Power should always be disconnected whenever installing, wiring or servicing a
gate operator. Moving chains in gate operators can catch clothing or fingers and
cause severe injury.
•Installation of wiring should comply with local building and electrical codes.
•All manual gate locks should be disabled to avoid damage to the gate or gate
operator should the lock become engaged after the operator is installed.
•All operator controls and safety equipment should be tested at the conclusion of
installation to be sure they are functioning properly.
•The operation of the gate controls and safety equipment should be reviewed with
the owner and/or end user of the automated gate system. They should also be
informed of the need to maintain control and safety equipment on a regular basis.
Safety equipment should be checked monthly to ensure it is working properly. All
installation manuals and safety information should be left with the owner.
•Moving gates have pinch points and entrapment zones which can be extremely
dangerous to pedestrians, especially small children.

BASIC INSTALLATION HINTS AND RULES
PLEASE READ THIS SECTION VERY CAREFULLY BEFORE BEGINNING YOUR
INSTALLATION
1. UNDERSTAND THE SYSTEM AND INSTALLATION SITE THOROUGHLY. The SL 1000 is a
flexible and reliable gate operator system, but the quality of service depends directly on the
quality of installation. Please read these instructions carefully and study the applicable diagrams
before planning your installation. In particular, understand any site characteristics that may
affect the system installation.
WARNING
2. INSTALL PERMANENT WIRING. U.L. specifications require the model SL 1000 system to be
permanently wired. Refer to your local wiring code for specific information.
WARNING: Damage caused by faulty wiring is not covered by warranty.
3. U.L. OBSTRUCTION-SENSING REQUIREMENTS. To maximize safety, U.L. 325 standards
require primary obstruction sensing (gate sensitivity to impact) and secondary obstruction
sensing (photo-sensors) be in operation at all times.
4. GROUND THE SYSTEM. The system contains parts which may be damaged by static
discharge. A proper earth ground connected to the gate operator housing (at the lower left
grounding screw shown in Figure 15) will significantly reduce the chances of damage or
improper operation. The shielding in the cables specified for all remote sensors and controls
should also be connected to earth ground at the controller end of the cable only.
To be effective, the ground connection must be made by running 12 awg copper wire to a good
ground point (e.g., an electrical panel, a metallic cold water pipe that runs into the earth, or a
grounding rod at least 10 feet in length that is driven into the earth) within 12 feet of the system.
Even if you have a good earth ground, you should try to discharge any static before handling the
boards.
WARNING: Damage caused by static discharge or lightning is not covered by warranty.
5. PROVIDE POWER FROM A DEDICATED SOURCE. The outlet into which you connect the
Gate Operator should be wired to its own circuit breaker. This will reduce the line noise
introduced into system power and minimize the risk of having other equipment interrupt system
operation. In a Master/Slave system, master and slave must each have separate circuits.
6. DO NOT OVERLOAD THE TERMINAL BLOCKS. The terminal blocks are removable and the
pins are soldered into the boards. To connect your wires, remove the “head” from the correct
terminals and open the screws. Insert the wire into the correct opening on the front and tighten
the screw until the wire is held firmly. When you have made all connections for a given “head”,
plug it back onto the inputs designated for that terminal block.
Stranded wire must be between 16 and 24 awg. Solid wire must be between 18 and 24 awg.
This is the total thickness measurement so, if you are putting two wires in, the combined
thickness must fall within this range. NEVER try to insert more than two wire per terminal.
7. ENSURE GOOD CONNECTIONS. A light tug on the wire will tell you if the connection is secure.
When reconnecting system components, make sure all pins are straight on chips, connectors,
and terminal block heads.
8. READ MARKINGS CAREFULLY. The connection points are marked on the boards clearly.
Before making any connection, be sure to read the marking and check it against the
corresponding figure in these instructions so that you understand the connection you are making.
9. TRAIN YOUR CUSTOMERS THOROUGHLY. Although customer responsibility is limited to
proper installation, the quality of service is determined by care of system programming. Ensure
that the customer has a copy of this manual to guide them. It will save you and them lots of
inconvenience and aggravation later.

B. PAD AND MOUNT
Figure 4. Pad and Track Ribbon
Figure 5. Bolt Down Pattern Figure 6. Conduit Entrance Areas
1. The concrete pad must be sufficient to support the gate operator and the forces
created by the moving gate. LiftMaster recommends a pad 20” wide by 30“ long by
24” deep (Figure 4).
2. The operator must be level and parallel to the gate, so the pad should be level and
about 4” above ground level to prevent water entrance.
3. Four anchor bolts are required to secure the gate operator to the pad. The mounting
holes in the gate operator are 5/8” in diameter. ½ ” x 3½ ” Red Head bolts are
recommended (Figure 5).
4. Be sure to provide access for wiring conduits (Figure 6).
5. Track installation should be on concrete, not asphalt, and should be at least 10” wide
and 6” deep.
6. A 6” gate overlap at the open end of the gate when closed should be provided.
7. A 30” gate overlap at closed end of the gate when closed should be provided.
NOTE: Shading indicates acceptable areas for conduit stub access.

Rev J Doc 01-20098 Page 8 of 44
C. POWER WIRING
1. Provide a separate conduit stub for the AC power.
2. Each gate operator requires a 115 VAC 20 AMP single phase circuit
NOTE: Master and Slave units each require separate circuits to prevent false
overcurrent faults (see X3 Series Master/Slave Systems).
3. Wiring must comply with the local Electrical Code for operating a 1/2HP motor. 12
AWG for up to 300' and 10 AWG for up to 500' long wire runs is suggested.
4. Be sure to pull a ground wire in the conduit for the connection to the gate operator.
NOTE: Do not rely on metallic conduit for earth ground.
D. LOOP DETECTORS AND PHOTO-SENSORS
1. A shelf is provided (10" x 11" x 18" high) to support non-LiftMaster loop detector
electronics. Power for the loop detector can come from the auxiliary 115 VAC plugs
in the gate operator or from the 24 VAC provided by the gate operator control board.
NOTE: The auxiliary plugs have power regardless of the unit power switch setting.
2. Conduit provisions should be made for the “loop” wire entrance to the loop detector.
3. Wiring should be 16-24 AWG stranded or 18-24 AWG solid.
NOTE: Optional LiftMaster-supplied loop detector add-on boards are available, both
pre-installed and for installation in the field. See Part 3, Gate Operator Options.
E. TELEPHONE CONNECTION
1. A conduit entrance into the gate operator should be provided for the telephone line.
2. A single twisted pair wire 18 AWG to 24 AWG, will be connected from the telephone
company termination block through the conduit to J9 on the control board. Polarity is not
important.
NOTE: Do not run telephone and AC power wires in the same conduit.
F. OTHER CONNECTIONS
1. Provisions should be made for conduit entrance into the gate operator for external
activation devices such as key switches, telephone entry systems, loops, etc.
2. Wire size requirement: 16-24 AWG stranded or 18-24 AWG solid wire should be used.
G. MASTER/SLAVE INTERCONNECTION (MASTER/SLAVE SYSTEM ONLY)
1. A conduit between the Master and Slave units should be provided for the Master/Slave
interconnection cable.
2. Two shielded twisted pair wire 16 AWG to 24 AWG will be connected between the two
units at TB1 on the controller board.
NOTES: 1. Do not run the Master/Slave cable and AC power wires in the same conduit.
2. Master/Slave interconnection cable should not exceed 3000' in length.
H. GROUNDING
1.
2.
The system contains parts which may be damaged by static discharge. A proper earth
ground connected to the gate operator housing will significantly reduce the chances of
damage or improper operation. The shielding in the cables specified for all remote
sensors and controls should also be connected to earth ground at the controller end of
the cable only.
To be effective, the ground connection must be made by running 12 AWG copper wire
to a good ground point (e.g., an electrical panel, a metallic cold water pipe that runs into
the earth, or a grounding rod at least 10' in length that is driven into the earth) within 12'
of the system. Even if you have a good earth ground, you should try to discharge any
static before handling the boards.
