2.3 - List of cables

Figure 2 shows the cables needed for the connection of the devices in a typical
installation; table 3 shows the cable characteristics.
Connection
A: Power line
B: Flashing light with aerial
C: Photocells
D: Key-operated selector switch
E: Main sensitive edge
F: Movable edges
Note 1 – power supply cable longer than 30 m may be used provided it has a larger gauge, e.g. 3x2.5mm
near the automation unit.
Note 2 – a single 4x0.5mm cable can be used instead of two 2x0.5mm

Note 3 – please refer to Chapter "7.3.1 STOP Input" in situations where there is more than one edge, for information about the type of connection recom-
mended by the manufacturer.
Note 4 – special devices which enable connection even when the leaf is moving must be used to connect movable edges to sliding leaves.

INSTALLATION
The installation of Road400 must be carried out by qualified per-
sonnel in compliance with current legislation, standards and regula-
tions, and the directions provided in this manual.

3.1 - Preliminary checks

Before proceeding with the installation of Road400 you must:
• Check that all the materials are in excellent condition, suitable for use and
that they conform to the standards currently in force.
• Make sure that the structure of the gate is suitable for automation.
• Make sure that the weight and dimensions of the leaf fall within the specified
operating limits provided in chapter "2.1 Operating limits".
• Check that the static friction (that is, the force required to start the movement
of the leaf) is less than half the "maximum torque", and that the dynamic
friction (that is, the force required to keep the leaf in movement) is less than
half the "nominal torque". Compare the resulting values with those specified
in Chapter "8 Technical Characteristics". The manufacturers recommend a
50% margin on the force, as unfavourable climatic conditions may cause an
increase in the friction.
• Make sure that there are no points of greater friction in the opening or closing
travel of the gate leaves.
• Make sure there is no danger of the gate derailing and risk of it exiting the
guide.
• Make sure that the mechanical stops are sturdy enough and that there is no
risk of the deformation even when the leaf hits the mechanical stop violently.
• Make sure that the gate is well balanced: it must not move by itself when it is
placed in any position.
• Make sure that the area where the gearmotor is fixed is not subject to flood-
ing. If necessary, mount the gearmotor raised from the ground.
• Make sure that the area in which the gearmotor is mounted allows it to be
easily released and that the manual manoeuvre is easy and safe.
• Make sure that the mounting positions of the various devices are protected
from impacts and that the mounting surfaces are sufficiently sturdy.
• Components must never be immersed in water or other liquids.
• Keep Road400 away from heat sources and naked flames; in acid, saline or
potentially explosive atmosphere; this could damage Road400 and cause
malfunctions or dangerous situations.
• If there is an access door in the leaf, or within the range of the gate move-
ment, make sure that it does not obstruct normal travel. Mount a suitable
interblock system if necessary.
• The control unit must be connected to a power supply line equipped with a
safety grounding system.
• The power supply line must be protected by suitable magneto-thermal and
differential switches.
• A disconnection device must be inserted in the power supply line from the
electrical mains (the distance between the contacts must be at least 3.5 mm
with an overvoltage category of III) or equivalent system, for example an out-
let and relative plug. If the disconnection device for the power supply is not
mounted near the automation, it must have a locking system to prevent unin-
tentional, unauthorised connection.

3.2 - Installation of the gearmotor

The gearmotor must be fastened directly to an already existing mounting sur-
face using suitable means, for example expansion screw anchors. Otherwise,
The cables used must be suitable for the type of installation; for
example, an H03VV-F type cable is recommended for indoor applications,
while H07RN-F is suitable for outdoor applications.

cables.

in order to fasten the gearmotor the installer must:
1. Dig a foundation hole with suitable dimensions referring to Figure 3.
2. Prepare one or more conduits for the electrical cables as shown in figure 4
3. Assemble the two clamps on the foundation plate setting one nut under-
neath and one on top of the plate.
The nut underneath the plate must be as shown in Figure 5 screwed so that
the threaded part protrudes above the plate by approximately 25÷35 mm.
4. Pour the concrete and position the foundation plate at the distances shown
in fig. 3, making sure it is level and in line with the leaf before the concrete
sets. Wait for the concrete to harden completely.
5. Remove the 2 upper nuts of the plate and then place the gearmotor onto
them.
Check that it is perfectly parallel to the leaf, then screw the two nuts and
washers supplied, as shown in Figure 7.
If the rack is already present, once the gearmotor has been fastened, use the
adjustment dowels as shown in Figure 8 to set the pinion of Road400 to the
right height, leaving 1÷2 mm of play from the rack.
Otherwise, in order to fasten the rack the installer must:
6. Release the gearmotor as shown in paragraph "Release and manual move-
ment" of Chapter "Instructions and Warnings for users of the ROAD gear-
motor"
7. Open up the leaf completely and place the first piece of the rack on the pin-
ion. Check that the beginning of the rack corresponds to the beginning of
the leaf, as shown in Figure 9. Leave a 1÷2mm play between the rack and
the pinion, then fasten the rack to the leaf using suitable means.
In order to prevent the weight of the leaf from affecting the gearmo-
tor, it is important that there is a play of 1÷2mm between the rack and
the pinion as shown in Figure 10.
8. Slide the leaf and use the pinion as a reference point to fasten other ele-
ments of the rack.
9. Cut away the exceeding part of the rack.
10. Open and close the gate several times by hand and make sure that the
rack is aligned with the pinion with a maximum tolerance of 5mm. Moreo-
ver, check that the play of 1÷2mm has been respected along the entire
length between the pinion and the rack.
11. Thoroughly tighten the two fixing nuts of the gearmotor making sure it is
well fastened to the ground. Cover the fixing nuts with the relative caps as
shown in figure 11.
12. Fix the two "Opening" and "Closing" limit switch brackets with the relative
dowels to the outer sides of the rack as shown in Figure 12. Consider that
the leaf will slide for about another 2÷3cm after the limit switch cuts in. The
brackets should be positioned at a sufficient distance from the mechanical
stops.
13. Lock the gearmotor as shown in paragraph "Release and manual movement"
of Chapter "Instructions and Warnings for users of the ROAD gearmotor".
3.3 - Installation of the various devices
If other devices are need, install them following the directions provided in the
corresponding instructions. Check this in paragraph "3.5 Description of electri-
cal connections" and the devices which can be connected to the Road400 in
Figure 15.

3.4 - Electrical connections

Only carry out electrical connections once the electricity supply to
the system has been switched off. Disconnect any buffer batteries pre-
sent.
