General safety precautions
This installation manual is intended for qualified personnel only
•Installation, electrical connections and adjustments must be per-
formed by qualified personnel, in accordance with Good Working
Methods and in compliance with the current regulations • Read
the instructions carefully before installing the product. Wrong
installation could be dangerous • Before installing the product,
make sure it is in perfect condition •
The packaging materials (plastic, polystyrene, etc.) should not
be discarded in the environment or left within reach of children,
as they are a potential source of danger • Do not install the product
in explosive areas and atmospheres: the presence of inflammable
gas or fumes represents a serious safety hazard • Make sure that
the temperature range indicated in the technical specifications is
compatible with the installation site • Before installing the motori-
zation device, make sure that the existing structure, as well as all
the support and guide elements, are up to standards in terms of
strength and stability. Verify the stability and smooth mobility of the
guided part, and make sure that no risks of fall or derailment subsist.
Make all the necessary structural modifications to create safety
clearance and to guard or isolate all the crushing, shearing, trapping
and general hazardous areas • The motorization device manufac-
turer is not responsible for failure to observe Good Working Methods
when building the frames to be motorized, or for any deformation
during use • The safety devices (photocells, safety edges, emergen-
ATTENTION! Important safety instructions.
Please follow these instructions carefully. Failure to observe
the information given in this manual may lead to
severe personal injury or damage to the equipment.
Keep these instructions for future reference.

cy stops, etc.) must be installed taking into account the applicable
laws and directives, Good Working Methods, installation premises,
system operating logic and the forces developed by the motorized
door or gate • The safety devices must protect against crushing,
cutting, trapping and general danger areas of the motorized door or
gate. Display the signs required by law to identify hazardous areas.
Each installation must bear a visible indication of the data identifying
the motorized door or gate • Before connecting the power supply,
make sure the plate data correspond to those of the mains power
supply. An omnipolar disconnection switch with a contact opening
distance of at least 3mm must be fitted on the mains supply. Check
that there is an adequate residual current circuit breaker and a
suitable overcurrent cutout upstream of the electrical installation
in accordance with Good Working Methods and with the laws in force
• When requested, connect the motorized door or gate to an effec-
tive earthing system that complies with the current safety standards
• Before commissioning the installation to the end user, make sure
that the automation is adequately adjusted in order to satisfy all the
functional and safety requirements, and that all the command, safe-
ty, and manual release devices operate correctly •
During installation, maintenance and repair operations, cut
off the power supply before opening the cover to access the
electrical parts • The protection cover of the operator must be
removed by qualified personnel only.
The electronic parts must be handled using earthed antistat-
ic conductive arms. The manufacturer of the motorization
declines all responsibility if component parts not compatible with
safe and correct operation are fitted • Only use original spare parts
for repairing or replacing products • The installer must supply all
information concerning the automatic, manual and emergency
operation of the motorized door or gate, and must provide the user
with the operation and safety instructions.

4.1 Preliminary checks
4. Installation
The declared operating and performance features can only be guaranteed with the use of Ditec
accessories and safety devices.
Unless otherwise specified, all measurements are expressed in mm.
Check that the structure of the gate is sturdy and that the hinges are lubricated and function
smoothly. If possible, provide an opening and closing stop, otherwise use the integrated mechan-
ical stops and/or the electric limit switch (optional) if available. The mechanical parts must be in
accordance with the provisions of the EN12604 standard.
The fixing point of the automation varies depending on the space available and the gate
to be automated, therefore it is up to the installer to choose each time the best solution
to ensure the correct operation of the system.
The installation measurements indicated in the table allow to choose the values of [A] and [B] on
the basis of the desired opening angle and in relation to the on site spaces and overall dimensions.
Increasing measurement [A], you reduce the opening approach speed.
Reducing measurement [B], you increase the degrees of gate opening.
Measurements [A] and [B] must, however, be compatible with the effective stroke of the piston.

After choosing the most suitable fastening point for the front bracket [14] to the gate wing, to de-
termine the height position, proceed with the sizing, positioning and fixing of the rear bracket [13].
If necessary, shorten the rear bracket [13] following measurement (S) in Tab. 4.1.
- Once you have fastened the rear bracket [13] following the measurements indicated on page 10,
fasten the front bracket [14] to the gate.
- With the gate completely closed, position the front bracket [14], in accordance with measure-
ment (L). Check that the front bracket [13] and rear bracket [14] are properly levelled as shown
in the following figures and fasten the front bracket [13] to the gate.
4.2 Bracket fastening
Configuration [A] is the one recommended for a greater mechanical resistance.
NOTE: If necessary, the front bracket [14] can be rotated and fixed as shown in figures
[B], in this way the operator position will be higher by about 40 mm.

The positioning of the brackets can be greatly simplified by using the positioning template (op-
tional accessory), which allows to establish with certainty the fixing positions and distances of a
bracket with respect to the other during installation. In this way positioning errors and incorrect
alignment of the fixing holes are avoided thanks to the level integrated in the template.
The installation template is compatible with all pistons of the PWR, Obbi and Luxo series.

• Open the release lock hatch [8], loosen the screw [9] and remove the rear cover [7].
• Release the piston by inserting the key [10] in the appropriate pin [11] and turn it counter-clock-
wise as indicated by the arrow.
• Insert the rear bushing [18] into the hole of the rear bracket [13] and lubricate the pivot points.
• Fix the piston to the rear bracket, fully tightening the M8x45 screw [19] to nut [20].
• Open the wing manually and insert the front mounting pin [15] into the hole of the front fastening
bracket [14]; block the pin in the bracket using the washer [16] and the M8x16 screw [17] supplied.
• Moving the gate manually, check that the entire stroke takes place without interference.

4.5 Adjusting the mechanical end stops
The mechanical end stops are adjusted in steps of 4 mm.
Example: GATE WING STOP at stroke [R] = 340 – 344 – 348 mm, etc.
If the stopping point of the gate wing does not coincide with the required position, remove the
mechanical end stop and rotate it 180° before replacing it in the toothed guide (as shown in the
figure below).
In this way, the mechanical end stops are still adjusted in 4mm steps, but at points differentiated
by 2 mm.
Example: GATE WING STOP at stroke [R] = 338 – 342 – 346 mm, etc.

4.6. Electrical connections
The PWR25H and PWR35H gear-motors can be connected to control panels LCU30 and LCU40.
To connect the automation to the control panel, proceed as follows:
• Remove the rear cover [9] as shown in paragraph 4.4;
• Fit the cable gland on the automation, securing it with the nut inserted in the hole in the casting
(Fig. 4.1 and 4.2), then insert the connecting cables (Fig. 4.3);
• Connect the various wires as shown in the wiring diagram in Fig. 4.4;
• Secure the rear cover [9] to the gearmotor.
The electrical wiring and start-up of the gear-motors PWR25H and PWR35H are shown in the
installation manuals of control panels LCU30 and LCU40.
A flexible corrugated Ø16 pipe and related Ø20 fitting (not supplied) can be used to increase pro-
tection of the motor cable.
