    Because GTO automatic gate openers are only part of the total gate operating system, it is the responsibility of the consumer to ensure that the total system is safe for its intended use.

  • Page 6: Important Safety Instructions For The Consumer

    IMPORTANT SAFETY INSTRUCTIONS For The Consumer WARNING: To reduce the risk of injury or death: READ AND FOLLOW ALL INSTRUCTIONS. Failure to meet the requirements set forth in the instruction manual could cause severe injury and/or death, for which the manufacturer cannot be held responsible. When designing a system that will be entered from a highway or main thoroughfare, make sure the system is placed far enough from the road to prevent traffic congestion.

  • Page 8 If any of these signs or warning decals become damaged, illegible or missing, replace them immediately. Contact GTO for free replacements. The gate is automatic and could move at any time, posing a serious risk of entrapment. No one should be in contact with an activated gate when it is moving or stationary.

  • Page 9: Secondary Means Of Protection Against Entrapment

    IMPORTANT SAFETY INSTRUCTIONS Secondary Means of Protection Against Entrapment As specified by Gate Opener Safety Standard, UL 325 (30A.1.1), automatic gate openers shall have an inherent entrapment sensing system, and shall have provisions for, or be supplied with, at least one independent secondary means to protect against entrapment.

  • Page 10: Required Safety Precautions For Gates

    Pedestrian Gate Entrapment Protection GTO’s inherent obstruction settings, even when properly adjusted, may not be sensitive enough to prevent bodily injury in some circumstances. For this reason, safety devices such as safety edge sensors (or photoelectric sensors), which stop and reverse gate direction upon sensing an obstruction, are suggested for enhanced protection against entrapment.

    • The system is powered by a 12 Vdc automotive or marine battery. • Battery charge is maintained by a 120 Vac, 18 Vac output transformer [rectified to 14.5 Vdc (40 VA) through the GTO control board] or by optional GTO Solar Panels [the panel should generate minimum of 5 W at 300 mA]. A diode on the control board prevents battery discharge.

  • Page 15: Installation Overview

    Installation Overview Pull-to-Open Gates (Gate Opens into the Property) The diagram shown below is an example of a pull-to-open installation on a chain link fence and single gate. Mounting the opener on a masonry column requires special procedures; see Column Installation Information on page 39 if you intend to mount the opener on a column.

  • Page 16: Installation Of The Mounting Hardware

    Installation of Mounting Hardware The position of the post bracket determines the leverage and efficiency of the opener. The post bracket position also sets the clearance between the opener and gate in the open and closed positions (minimum 2 inches for safety reasons). The curved design of the post bracket works well for installations on round and square fence posts.

  • Page 18 for minimum 2 inches of clearance between the gate and the opener in both the open and closed positions, as shown in the diagrams below. This clearance will give the opener the most efficient leverage point for opening and closing the gate and more importantly provides the least possible pinch area.
  • Page 19 Installing the Post Bracket Assembly and Gate Bracket Step 7 Mark reference points for bolt holes on the fence post through middle of bracket slots. Marking reference points in this manner allows room for adjustment when mounting the post bracket assembly and gate bracket.

  • Page 20: Mounting The Opener

  • Page 22: Powering The System

    Powering the System IMPORTANT: • The Mighty Mule 350 is designed and intended for use with a 12 Volt automotive or marine type battery. The battery must be placed inside a weatherproof case and located within 6 feet of the opener arm. The 10 foot harness supplied connects the battery to the opener arm.

    23. IMPORTANT INFORMATION ABOUT LOW VOLTAGE WIRE The only wire acceptable for use with GTO products is 16 gauge multi-stranded, low voltage, PVC sheathed wire. This particular gauge enables the transformer to provide an adequate charge through the control board to the battery at distances up to 1000 ft.
  • Page 26 Strip " off the ends of the low voltage wire and twist tightly. Insert these ends to the 18 VAC terminal block located on the control board (see illustration at right). The wires can be inserted into either terminal regardless of color. Be certain not to let the exposed wires touch each other! Tighten set screws against exposed end of wires.

  • Page 27: Connecting Solar Panel(S)

    Connecting Solar Panel(s) IMPORTANT: Never connect the transformer and a solar panel to the opener control board at the same time. It will damage the control board. If you are using the transformer included with the Mighty Mule 350 to charge the opener battery, skip this section and go to "CONTROL BOARD SETTINGS"...
