BASIC INSTALLATION HINTS AND RULES
PLEASE READ THIS SECTION VERY CAREFULLY BEFORE BEGINNING YOUR INSTALLATION.
In the sections that follow, detailed procedures are discussed for each step required to install a model
SL 1000-X1 system. In addition to these specific procedures, there are a number of general hints and
rules which will help ensure that your installation will be done correctly and efficiently. These are
discussed below.
1. UNDERSTAND THE SYSTEM AND INSTALLATION SITE THOROUGHLY. The SL 1000-X1 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-X1 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. 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 16) 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.
4. 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.
5. DO NOT OVERLOAD THE TERMINAL BLOCKS. The terminal blocks used in the gate operator 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 pins 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 wires per terminal.
6. 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.
7. READ THE 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.
8. 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 the manual, Programming Instructions for LiftMaster SL 1000-X1 and SW
2000-X1 Gate Operators (Doc. No. 6001193) to guide them. It will save you and them lots of
inconvenience and aggravation later.
