Preliminary Checks; Installation Of The Gearmotor - Nice Robus 350 Instrucciones Y Advertencias Para El Instalador

3.1) Preliminary checks

Before proceeding with the installation of ROBUS350 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 Char-
acteristics". 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 open-
ing or closing travel of the gate leaves.
• Make sure there is no danger of the gate derailing.
• Make sure that the mechanical stops are sturdy enough, and that
there is no risk of deformation even when the leaf hits the mechan-
ical 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 there is no risk of flooding in the area the gearmotor is
fixed to. Mount the gearmotor raised from the ground if necessary.

3.2) Installation of the gearmotor

The gearmotor must be fastened directly to an already existing
mounting surface using suitable means, for example expansion
screw anchors. Otherwise, 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
underneath and one on top of the plate. The nut underneath the
plate must be screwed to the end of the thread so that the threa-
ded part protrudes above the plate by approximately 25÷35 mm.

• Make sure that the installation area enables the release of the
gearmotor and that it is safe and easy to release it
• Make sure that the mounting positions of the various devices are
protected from impacts and that the mounting surfaces are suffi-
ciently sturdy.
• Never immerse components in water or other liquids.
• Keep ROBUS350 away from sources of heat and open flames and
acid, saline or potentially explosive atmospheres. Situations such
as these could damage ROBUS 350 and cause either malfunc-
tions or dangerous situations.
• If there is an access door in the leaf, or a within the range of move-
ment of the gate, make sure that it does not obstruct normal trav-
el. Mount a suitable interblock system if necessary.
• Only connect the control unit 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 3.5mm with an overvoltage category of III) or equivalent
system, for example an outlet and relative plug. If the disconnec-
tion device for the power supply is not mounted near the automa-
tion, it must have a locking system to prevent unintentional, unau-
thorised connection.
4.Pour the concrete and, before it starts to harden, set the founda-
tion plate to the values shown in Figure 3. Check that it is parallel
to the leaf and perfectly level. Wait for the concrete to harden com-
pletely.
5.Remove the 2 upper nuts of the plate and then place the gear-
motor onto them. Check that it is perfectly parallel to the leaf, then
screw the two nuts and washers supplied, as shown in Figure 7.
