INTRODUCTION
Before installing the gate opener, ensure that the gate is opening smoothly. Determine dimensions based on the
opening angle provided in Table 1 (below) to confirm the position where the post bracket will be mounted. Ensure
that all the required cables (power cable, accessory cables etc) are prepared and laid correctly.
NOTE: All crushing points must be secured by an entrapment protection according to AS/NZS 60335.1 in conjunction with
AS/NZS 60335.2.103.

Wind Load Rating for Swing Gate Operators
We do not have wind load ratings on our gate openers, as Chamberlain is not responsible for how gate installers design their gates.
Recommendations
• Do not use a solid leaf/panel gate in windy areas.
• Use a light weight picketed slide or swing gate to minimize the wind force.
• Try using a maglock or e-lock to keep the gate securely shut.
• It may be needed to hold the gate(s) open or close, in windy applications.
• When selecting an opener, be sure to select the correct opener for the size of gate.
• You may need to adjust the gate force margins in high wind applications.
Power Wiring
1. The 240V AC opener is supplied with a mains power plug pre-assembled ready for installation.This may require mains power
supply to be provided close to the opener by a licensed electrician.
2. The 24V AC opener will require a low-voltage power supply from the transformer box (MGTR3-120VA) to the gate opener.
3. The recommended cable sizes for the connection between the transformer box and the Low Voltage (LV) openers:
• Flexible 3 core cable:
• Less than 20m, minimum 1.5mm²
• 20m to 50m, minimum 2.5mm²
• 50m to 100m, minimum 4mm²
4. It is recommended that the Low Voltage (LV) power cable is run inside conduit to the opener as per local installation requirements.
Suitable cable glands must be used that provide sufficient cable restraint against a minimum of 30 N pull force.
Earthing Recommendations
Proper earthing of the opener is recommended to improve the radio range of transmitters and wireless accessories.
• The 240V AC unit is earthed using the standard AC power plug provided
• For the Low Voltage unit earthing can be achieved by running an earth wire back to the transformer box
• Alternatively connect the earth wire supplied with the LV unit to a suitable earth point on the operator base plate
• The use of an extension antenna kit SWG-ANT-EV may also be used to improve the radio range.
Additional Accessories
The vehicle loops allow the gate to stay open when vehicles are obstructing the gate path. Suggested for vehicles 4.2m or longer.
Vehicle loops are not required but are recommended. Before installing any accessories be sure to complete a site check to determine
the best device(s) the site needs.
