WARNING With not self-locking models, with same leaf
length, reduce of 1/3 the door admissible weight compared to
what indicated in "Length-weight" chart.
WARNING In case the leaf is more than 2 m long or in
case you use not self-locking models, an electric-lock must be
installed to hold the gate in closing position.
4.5.1 Installation, assembly and disassembly
The following operations are essential to the correct laying
of the product:
• The careful definition of the entire automatic opening layout
(see also "6 Complete Closing Assembly"); in particular,
after carefully assessing the characteristics of the supports
and the gate, the attachments must also be designed and
positioned according to the angle of opening desired (see
F2, F3 Page 38-39).
• Verify that any mechanical feature of the gate are in good
conditions and allows a safe automation. Moreover check the
balancing, gate has to correctly and freely move on its hinges
and once stopped in any position, it has to stay blocked.
The fastening of the attachments must be performed with
extra care on both pillars and gate, here are the dimensions
suggested by DEA SYSTEM (see F3 page 39). Pay extra at-
tention to the horizontal alignment between rear fastening
support and front one.
General considerations to establish the installing dimen-
sions:
• The sum of A + B for 90° openings is equal to C rod run
• A + B < C to increase the opening angle
• A and B lower than what suggested, involve a higher door
tangential speed
• If A and B are 5 cm greater than what suggested, limit
switches (if foreseen) adjustment won't be possible

To install the operator proceed as follows:
• Weld or screw the rear fastening support to the pillar, in pre-
fixed position
• Apply LOOK to the rear fastening support
• Execute the manual unlocking operation (see following para-
graph) and take off completely the rod
• Lock LOOK again and turn the rod half way
• Fix the frontal fastening support to LOOK rod
• Weld or screw the frontal fastening support to the door (with
door completely closed), by keeping LOOK in an horizontal
position
• Unlock again and make a complete opening and closing
cycle, this is to check that gate moves freely and without any
hindrance (with cover rod)
WARNING In order to make the structure sufficiently strong,
reinforcement plates to be fixed to attachments may be ne-
cessary
WARNING Grease pins before assembly

• For versions that foresee the cover rod, adjust limit switches
while assembling (see page 34)
4.5.2 Starting and adjustment
WARNING During the connection phase, fasten the
electric cables with appropriate clamps near the terminal
boards and, when possible, unsheathe the cables to avoid
they are too long.
LOOK must be electrically connected to a DEA SYSTEM con-
trol panel; refer to the instructions provided for such device for
further information.
For LOOK wiring, proceed as follows (se also page 33):
24V/230V standard version
• Remove the plastic cover positioned under LOOK
• Open one of four shaped holes and choose where the cable
exit has to be
• Introduce the cable clamp and fix it by its nut
• Insert the power supply cable into the clamp (coming from
the control panel): A quadrupole cable suitable for external
applications with a 4x1mm² section (or 2x1,5mm² for 24V
operators)(minimum H05RN-F type) coming directly from
the control panel (without any connection and shunt box)
and supplied by the installer;
WARNING: do not remove too much outer insulation on the
power supply cables.
• Execute motor connections as indicated:
24/230V version with limit switches
• For the operator power supply connection follow the instruc-
tions of the basic version.
• Open a second hole in the plastic cover and apply the se-
cond provided cable clamp (a reduced M16).
• Use a 3x0,75mm² cable (not supplied) and look at the dia-
gram at page 11 for a correct limit switches wiring to the
control panel.
230V version with encoder
• For the operator power supply connection follow the instruc-
tions of the basic version.
• Open a second hole in the plastic cover and apply the second
provided cable clamp (a reduced M16).
• Use a 3x0,5mm² LiYY (DEA art. 182021) to be ordered a
part) and follow the diagram on page 11 to correctly connect
the encoder to the control board.
• Use the cable with panduit connector supplied in the kit to con-
nect the previously used cable to the control board, by using the
clamp 3 "poli" inside the package.
WARNING: Maintain the ground conductor at a major length
respect the active conductors so that, if the cable exit from its
fixing housing, the active conductors tighten up as first.
WARNING: Respect the Phase-Neutral polarity of the tension as
explained by the instructions manual of the control panels
of LOOK.
• Re-assemble the plastic cover ensuring that any cable do not
touch moving parts of the operator
WARNING: LOOK limit switches have been exclusively foresaw
to directly connect their inputs to the control panel and so
they are submitted to a very safety low tension. Therefore
keep a proper distance between limit switches cables and
power supply cable of 230V operator.
WARNING: while installing, maintain a proper distance between
the power cable conductors and the operator
