Use suitable tubes and/or hoses to lay electric cables
To avoid any kind of interference always separate low-vol-
tage accessories and control cables from 230/115 V~ power
supply cables using separate sheaths.
3.2. PRELIMINARY CHECKS
To ensure a correct operation of the automated system, make sure
the following requirements are observed as for the gate structure
(existing or to be created):
the mechanical parts must conform to the provisions of Standards
EN 12604 and EN 12605.
leaf length in compliance with the operator specifications.
sturdy and stiff structure of the leaves, suitable for automation.
regular and uniform movement of the leaves, without any friction
and dragging during their entire opening.
with the reversible motors to verify that the gate does not move
alone.
stiff hinges in good conditions.
presence of both opening and closing mechanical limit stops.
presence of an efficient earthing for electrical connection of
the operator.
Perform any necessary metalwork job before installing the
automated system
.
The condition of the gate structure directly affects the reliability
and safety of the automated system
.
3.3. INSTALLATION DIMENSIONS
Determine the fitting position of the operator with reference to
Fig.4.
Check with care if the distance between the open leaf and any
obstacles (walls, fences etc.) is higher than the operator dimen-
sions.
