amendments.
• Disconnect the electrical power supply before carrying out any work on
the installation. Also disconnect any buffer batteries, if fitted.
• Fit an omnipolar or magnetothermal switch on the mains power supply,
having a contact opening distance equal to or greater than 3,5 mm.
• Check that a differential switch with a 0.03A threshold is fitted just before
the power supply mains.
• Check that earthing is carried out correctly: connect all metal parts for
closure (doors, gates etc.) and all system components provided with an
earth terminal.
• Fit all the safety devices (photocells, electric edges etc.) which are needed
to protect the area from any danger caused by squashing, conveying and
shearing.
• Position at least one luminous signal indication device (blinker) where it
can be easily seen, and fix a Warning sign to the structure.
• The Company declines all responsibility with respect to the automation
safety and correct operation when other manufacturers' components are
used.
• Only use original parts for any maintenance or repair operation.
• Do not modify the automation components, unless explicitly authorised
by the company.
• Instruct the product user about the control systems provided and the
manual opening operation in case of emergency.
• Do not allow persons or children to remain in the automation opera-
tion area.
• Keep radio control or other control devices out of children's reach, in
order to avoid unintentional automation activation.
• The user must avoid any attempt to carry out work or repair on the automa-
tion system, and always request the assistance of qualified personnel.
• Anything which is not expressly provided for in the present instructions,
is not allowed.
• Installation must be carried out using the safety devices and controls
prescribed by the EN 12978 Standard.

2) GENERAL OUTLINE

The LIBRA-C-MA control panel is supplied by the manufacturer with standard
setting. Any alteration must be set by means of the incorporated display
programmer or by means of UNIPRO. The Control unit completely supports
the EELINK protocol.
Its main characteristics are:
- Control of two low-voltage motors up to 40W power
- Electronic torque setting with obstacle detection
12 - LIBRA-C-MA - Ver. 04
INSTALLATION MANUAL
- Limit-switch control inputs
- Separate inputs for safety devices
- Incorporated rolling-code radio receiver with transmitter cloning
The board is provided with a terminal board which can be pulled out for
easier maintenance or replacement. The board is supplied with a series of
pre-wired jumpers to facilitate the installer's work.
The jumpers relate to the following terminals:
23-26 and 23-27.
respective jumpers.
CHECK
The LIBRA-C-MA panel carries out a control (check) on the starting relays and
safety devices (photocells) before carrying out each opening and closing cycle.
In case of malfunction, check the devices connected for regular operation
and check the wiring.

WARNING – During the wiring and installation operations, refer to the current
standards as well as principles of good technical practice.
Wires powered at different voltages must be physically separated, or suitably
insulated with at least 1 mm extra insulation. The wires must be clamped by
an extra fastener near the terminals, for example by bands.
All the connection cables must be kept at an adequate distance from the
dissipator.
WARNING! For connection to the mains, use a multipolar cable with
a minimum of 3x1.5mm
ously mentioned regulations.
with a minimum cross section of 2.5 sq mm, of the type prescribed by
current standards.
For example, if the cable is out side (in the open), it has to be at least
equal to H07RN-F, but if it is on the inside (or outside but placed in a
plastic cable cannel) it has to be or at least egual to H05VV-F.
