FAAC Model 770 Underground Swing Gate Operator
The FAAC 770 is an electomechanical operator for swing gates. It
is designed for underground installation and therefore does not alter
the appearance of the leaf.
The supplied foundation box allows you to setup the gate before
actually installing the operator.
The 770 electromechanical operator is irreversible, so it ensures a
mechanical stop and eliminates the need to install an electric lock.

3.1. PRELIMINARY CHECKS
To ensure trouble-free operation, ensure that the gate (whether exist-
ing or yet to be installed) adheres to the following specications:
• Max. single leaf weight: 1100 lbs.
• Max. single leaf length: 98.5 inches.
• Strong and rigid leaf frame.
• Smooth gate movement, with no stiff points.
• Proper minimum clearance between bottom edge of gate and
ground. See Fig. 6a (where ‘s’ = thickness of guide bracket)
• Mechanical travel stops.
The condition of the gate directly affects the reliability and safety of
the automation system. If any welding has to be done on the gate,
complete it before installing the automation system.

a) For Existing Gates with Fixed Hinges:
• Remove the gate.
• Remove the bottom hinge.
If the gate cannot be removed, place blocks under its bottom edge to
support it.

1) Use suitable rigid/exible pipes for laying power cables.
2) Always keep low voltage accessory cables separated
from 230V~ power cables. To avoid interference, use
separate sheaths.
