Thank you for choosing our product. FAAC is sure that it will give you
all the performances you are looking for. All our products are the
result of a long experience in the field of the automated systems.
In the middle of the manual you will find a detachable
booklet containing all the images for the installation.
The 391 automated system consists of a non-reversing electro-
mechanical operator available in two versions:
• 391 E with built-in control unit
• 391 without control unit
The operator was designed for automating the opening of gates
with one or two leaves, with maximum length of 2.5m.
A handy, safe releases system, with personalised key, moves the
leaf in case of a power cut or fault.
The two articulated arms are designed for moving gates with very
large pilasters. The distance between the hinge and the gear-
motor securing point can be up to 220 mm. Thanks to the special
geometry of the two arms, all possible shearing points have been
eliminated.
IMPORTANT WARNINGS FOR THE INSTALLER
Carefully read the whole manual before beginning to install the
operator.
Store the manual for future reference.
The correct operation and the declared technical specifications
are only valid if the instructions given in this manual are strictly
observed and only FAAC accessories as well as safety device
are used.
To guarantee an adequate level of safety of the automated
system, the use of a control unit with an adjustable electronic
clutch is necessary due to the lack of a mechanical clutch .
The automated system was designed and built to control vehicle
access. Avoid any other use.
The operator cannot be used to move safety exits or gates
installed on emergency routes (escape routes).
Do not transit when the rod is moving.
Anything not expressly specified in this manual is not permitted.

connect the MASTER and SLAVE operators.
4. INSTALLATION
4.1. PRELIMINARY CHECKS
To ensure a correctly operating automated system, the structure of
the gate to be moved must satisfy the following requirements:
The mechanical construction elements must comply with the
provisions of the EN12604 and EN 12605 standards.
leaf length must conform to the operator characteristics (see
paragraph 2)
sturdy, rigid gate structure, suitable for the automated system
smooth, uniform gate movement, without any friction and jam-
ming during the entire opening;
adequately sturdy hinges, in good condition
an efficient earth socket for connection of the operator
We advise you to carry out the metalwork jobs if any, before
installing the automated system.
The condition of the gate structure directly influences the
reliability and safety of the automated system.
If the leaf to be motorised incorporates a door for the pedestrian
passage it is compulsory to add a safety switch on the door,
connected to the stop input, in order to inhibit the operation
of the automated system when the door is open.
The gearmotor cannot be used to move safety exits or gates
fitted on emergency routes (escape routes).
