2) Product description and applications

NAKED is a line of irreversible electromechanical gearmotors for the
automation of sliding gates. It is equipped with an electronic control
unit and connector for the optional SMXI or SMXIS radiocontrol
receiver. The electrical connections to external devices have been
simplified through the use of "BlueBUS", a technique by which sev-
eral devices can be connected up using just 2 wires. NAKED oper-
Other products are also part of the NAKED line, the difference of which is described in table 1.

2.1) Operating limits

Chapter 8 "Technical Characteristics" provides the only data needed
to determine whether the products of the NAKED line are suitable for
the intended application.
The structural characteristics of NAKED make it suitable for use on slid-
ing leaves in conformity with the limits indicated in tables 2, 3 and 4.
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 interfere with the movement of the leaf.
For an effective control it is absolutely vital to measure the force nec-
essary to move the leaf throughout its entire run and ensure that this
is less than half of the "nominal torque" indicated in chapter 8 "Tech-
nical 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 consideration the

ates with electric power. In the event of a power failure, the gearmo-
tor can be released using a special key in order to move the gate
manually. Alternatively, there is the PS124 buffer battery (optional
accessory) which makes it possible to use the gate also during the
event of a power failure.
