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-
cy stops, etc.) must be installed taking into account the applicable
ATTENTION! Important safety instructions.

4. Installation
The given operating and performance features can only be guaranteed with the use of DITEC ac-
cessories and safety devices. Unless otherwise specified, all measurements are expressed in mm.
4.1 Preliminary checks
Make sure the gate structure is sturdy and the hinges are lubricated and smooth.
If possible, fit an opening and closing stop. Otherwise, use the mechanical stops (integrated
for opening stop with PWR50AC, optional for closing stop with PWRFM, integrated for opening
and closing stops with PWR50H/HR) and/or the electromechanical limit switches (included for
PWR50HV) if available. The mechanical construction elements must comply with the requisites
of Standard EN12604.
The automation fastening point varies according to the space available and the gate to
be automated. The installer must therefore choose the best solution to ensure that the
system works correctly in each individual situation.
The installation measurements indicated in the table allow you to choose the values of [A] and [B]
on the basis of the required opening angle and in relation to the on-site spaces and overall dimen-
sions.
Increasing measurement [A], you reduce the approach speed during opening.
Reducing measurement [B], you increase the gate opening angle.
Measurements [A] and [B] must, however, be compatible with the effective motor stroke.

13
IP2393EN
4.2 Fastening the brackets
After selecting the most suitable point for fastening the front bracket [18] to the gate wing, to
establish its height you must first size, position and fasten the rear bracket [17].
If necessary, shorten the rear bracket [17] following the indications given in Tab. 4.1.
-Once you have fastened the rear bracket [17] following the measurements given on page 9,
fasten the front bracket [18] to the gate.
- With the gate fully closed, position the front bracket [18], respecting the measurement (L).
Make sure the front bracket [18] and rear bracket [17] are properly levelled, as shown in the
figures below, then fasten the front bracket [18] to the gate.

IP2393EN
4.3 Using the mounting tool
During installation, the bracket positioning operation can be greatly simplified by using the
mounting tool (PWRMI - optional accessory), which allows you to ascertain the correct fastening
position of the brackets and the distance between them. This avoids positioning errors and incor-
rect fastening hole alignment, thanks also to the built-in spirit-level.
The mounting tool is compatible with all the pistons of the PWR, Obbi and Luxo series.

4.4 Installing the gear motor
• Open the lock hatch [8], loosen the 3.9x22mm screw [9] and remove the rear cover [7].
Loosen the screw M4 x 8mm [10] and take out the front cover [11] as shown in the figure.
Release the motor by inserting the key [23] in the relative lock [24] and turning it clockwise (see
the USER INSTRUCTIONS).
• Fasten the motor to the rear bracket [17] using the M8 x 45mm screw [19], the bush [20] and
the Ø 24mm washer [21], then tighten the M8 self-locking nut [22] as far as it will go.
• Open the gate wing manually and insert the front coupling pin [25] in the slot of the front fas-
tening bracket [18]. Lock the pin in the bracket using the washer Ø30mm [26] and nut M16 [27]
supplied. Before installing the motor, grease the rotation points.
NOTE: pay special attention to the correct assembly of the washer on the brackets.
• For PWR50H/HR/HV insert the protective brushes [12] in the relative guides on the front cover
[11] (see Fig. 4.1b).
• After making the adjustments (par. 4.5), insert the front cover [11] on the drive screw and fix it
in place using the screw [10].
NOTE: make sure the drive screw [25] enters the head [28] of the cover [11] correctly (detail
in figure 4.1a).
