sioned as specified in the chapter on "Testing and commissioning".
• Inspect the automation mechanism frequently to check for unbalancing, signs
of wear or damage to electrical cables and mechanical parts. Do not use the
automation mechanism if adjustment or repair is required.
• If it is not used for a long time, remove the optional battery (PS124) and keep
it in a dry place to make sure it does not leak harmful substances.
• Packaging materials must be disposed off in accordance with local regula-
tions.

1.3 - Warnings for use

• The product is not intended for use by persons, including children, with limit-
ed physical, sensory or mental capacities, or who lack experience or knowl-
edge, unless supervised or trained in the use of the product by a person
responsible for their safety.
• Any children near the automation system must be kept under supervision to
ensure that they do not play with it.
• Do not allow children to play with the fixed control devices. Keep remote con-
trol devices out of the reach of children.
• Clean the surfaces of the product with a soft, slightly damp cloth. Use only
water; do not use cleaning products or solvents.
PRODUCT DESCRIPTION AND

INTENDED USE
This product is intended for use to automate sliding gates for residential use; it
is a retractable gearmotor which may be installed in a column. IMPORTANT! –
All uses other than the intended use described and use in environmental
conditions other than those described in this manual should be consid-
ered improper and forbidden!
Naked combines an electronic control centre with a finger joint. Electrical con-
nections with external devices are simplified thanks to use of the "BlueBUS", a
technique permitting connection of multiple devices with only 2 wires.
If powered from the grid, Naked can host a buffer battery (mod. PS124, optional
accessory) which permits the automation mechanism to continue to perform a
number of manoeuvres even in the event of a black-out. In the event of a black-
out, it is still possible to move the gate by releasing the gearmotor using the key
provided (see point 3.7); or you may use the optional accessory: PS124 buffer
battery permitting a number of manoeuvres even in the absence of grid power.
The automation mechanism permits installation of various accessories to add
functions and improve security.

INSTALLATION

3.1 - Pre-installation checks

Important! - The installation of NAKED must be carried out by qualified
personnel in compliance with current legislation, standards and regula-
tions, and the directions provided in this manual.
Before proceeding with the installation of NAKED 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 spe cified
operating limits provided in chapter "3.2 Operating limits".
• Check that the force required to start the movement of the leaf is less than
half the "maximum torque", and that the force required to keep the leaf in
movement is less than half the "nominal torque". Compare the resulting val-
ues with those specified in Chapter "8 Technical Characteristics". The manu-
facturers recommend a 50% margin on the force, as unfavourable climatic
conditions may cause an increase in the friction.
• Check that the internal dimensions of the column are appropriate (at least
140 x 140 mm).
• Check the seats prepared for fixing the column.
• Check that there is enough space in the area at the back inside the column to
insert the gearmotor, pass the cables through and connect them.
• Check that the column is correctly earthed in the installation.
• Important! – Make sure that the column has been prepared correctly in
compliance with local legislation and guarantees a protection of at least IP44
when the lid is closed.
• Make sure that there are no points of greater friction in the opening or closing
travel of the gate leaves.
2 – English
• 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 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 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 sufficiently sturdy.
• Components must never be immersed in water or other liquids.
• Keep NAKED away from heat sources and open flames; in acid, saline or
potentially explosive atmosphere; this could damage NAKED and cause mal-
functions or dangerous situations.
• If there is an access door in the leaf, or within the range of movement of the
gate, make sure that it does not obstruct normal travel. Mount a suitable
interblock system if necessary.
• Connect the gate to the protective earth in accordance with current legislation.
• Provide a device on the electrical power line ensuring complete disconnec-
tion of the automation mechanism from the grid. The disconnection device
must have contacts with an opening distance large enough to permit com-
plete disconnection under the conditions sanctioned by overvoltage catego-
ry III, in accordance with installation regulations. The device ensures quick,
safe disconnection from the power supply if needed, and must therefore be
positioned in view of the automation mechanism. If, on the other hand, it is
located in a position which is not visible, there must be a system for prevent-
ing accidental or unauthorized reconnection with the power grid to prevent
this risk. The disconnection device is not supplied with the product.

3.2 - Operating limits

Chapter 8 "Technical Characteristics" provides the only data needed to deter-
mine whether the products of the NAKED line are suitable for the intended
application.
The structural characteristics of NAKED make it suitable for use on sliding leaves in
conformity with the limits indicated in tables 1 and 2.
The effective suitability of NAKED to automate a particular sliding gate depends
on the friction as well as other correlated factors, such as ice, that could inter-
fere with the movement of the leaf.
For an effective control it is absolutely vital to measure the force necessary to
move the leaf throughout its entire run and ensure that this is less than half of
the "nominal torque" indicated in chapter 8 "Technical characteristics" (a 50%
margin on the force is recommended, as unfavourable climatic conditions may
cause an increase in the friction); furthermore, it is necessary to take into con-
sideration the data indicated in tables 1 and 2 to establish the number of
cycles/hour, consecutive cycles and maximum speed allowed.
NKSL400 - Limits in relation to the length of the leaf
Leave width (m)
Up to 4
4 ÷ 6
NKSL400 - Limits in relation to the weight of the leaf
Leaf weight (kg)
Up to 200
200 ÷ 400
The length of the leaf makes it possible to determine both the maximum num-
ber of cycles per hour and consecutive cycles, while the weight makes it possi-
ble to determine the reduction percentage of the cycles and the maximum
speed allowed. For example if the leaf is 5 m long it will be possible to have 23
cycles/hour and 11 consecutive cycles. However, if the leaf weighs 350 Kg,
they must be reduced to 50%, resulting in 11 cycles/hour and 5 consecutive
cycles, while the maximum speed allowed is V5: "very fast". The control unit
has a limiting device which prevents the risk of overheating based on the load
of the motor and duration of the cycles. This device triggers when the maxi-
mum limit is exceeded. The manoeuvre limiting device also measures the ambi-
ent temperature reducing the manoeuvre further when the temperature is par-
ticularly high.
