BASIC INSTALLATION HINTS AND RULES
READ THIS SECTION CAREFULLY BEFORE BEGINNING YOUR INSTALLATION.
1. UNDERSTAND THE SYSTEM AND INSTALLATION SITE THOROUGHLY. The SW
2000 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. UL specifications require the SW 2000 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 (see Figure 12) 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 circuit boards.
WARNING: Damage caused by static discharge and 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 to reduce line noise 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 loosen 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.
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 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.
9. TRAIN YOUR CUSTOMERS THOROUGHLY. Although customer responsibility is limited
to proper installation, the quality of service is determined by the care of system setup.
Ensure that the customer has a copy of this manual to guide them.
