Works Prior To Installation; Electrical Cables Preparation - Nice Riva Instructions Et Avertissements Pour L'installation Et L'utilisation

Durability calculation example (refer to Table 1 and to Graph 1):
- leaf length: 1.7 m and leaf weight: 200 kg = severity index: 20%
- Installation in windy areas = severity index: 15%
- no other fatiguing elements present
Total severity index = 35%
Estimated durability = 120,000 manoeuvre cycles

4.1 - WORKS PRIOR TO INSTALLATION

4.1.1 - Establish the position of the devices in the system
With reference to fig. 3 and fig. 4, locate the approximate position for
installation of each device envisaged in the system. The fig. 3 shows a
system built with this product plus other optional accessories from the
Nice Home line. The various elements are positioned according to a
standard and usual layout. The devices used are:
a) - 1 CLB201 command control unit
b) - 1 FL200 flashing indicator with built-in antenna
c) - 1 pair of PH200 photocells (made up of a TX and an RX)
d) - 2 RIVA200 electromechanical gearmotors
WARNING! - Some of these devices are optional and may not be
present in this package (see the Nice Home product catalogue).
WARNINGS:
Fixed type control devices must be positioned:
- in view of the automation;
- away from its moving parts;
- at a minimum height of 1.5 m from the floor/ground;
- not accessible to strangers.
4.1.2 - Establish the position of all the connecting cables
Refer to the instructions in section 4.2 to determine the pattern with which
to dig the routes for the cable ducts for the electrical cables.
4.1.3 - Obtain the tools and materials required for the work
Before beginning work, make sure you have all the tools and materials
required to carry out the work. Make sure that these are in good condition
and comply with local safety regulations.
4.1.4 - Carry out the preparatory works
Prepare the environment for the subsequent installation of the devices,
carrying out preliminary work such as, for example:
- excavation of routes for the cable ducting for the electrical cables (alter-
natively, external raceways may be used);
- installation of the cable ducting and their attachment in the concrete;
- sizing of all electrical cables to the desired length (see section 4.2) and
their passage in the ducting. Caution! - At this stage do not imple-
ment any type of electrical connection.
Warnings:
• Ducting and raceways are used to protect the electrical cables from
damage due to accidental impacts.
• When laying the ducting, also take into account that due to possible
deposits of water in the routing ducts, the ducting might create con-
densation in the control unit, with consequent damage to the electronic
circuits.

A - Electricity supply line
B - FLASH flasher output
C - Radio antenna
D - ECSbus devices cable
- STOP input
- SbS input
G - Gearmotor power supply cable
Note 1 - You may use a cable which is longer than 30 m, provided it has a larger gauge (for example, 3 x 2.5 mm
with, in the vicinity of the automation, safety grounding.
Note 2 - For the ECSbus cables and those for the STOP and SbS inputs, you can also use a single cable with more internal conductors, to
group multiple connections.
CAUTION! – The cables used must be suited to the installation environment; for example a cable type H03VV-F for indoor envi-
ronments, or type H07RN-F for outdoor environments, is recommended.

4.2 - ELECTRICAL CABLES PREPARATION

To prepare all connection cables, proceed as follows.
a) - Observe fig. 4 to understand how the various devices should be con-
b) - Observe fig. 4 to understand how to position the electrical cables in
c) - Read Table 2 to determine the type of cables to use; then use the
WARNING - The "ECSbus" technology allows you to connect multiple
devices together using, between one device and the next, a single "bus"
cable, with two internal electrical conductors. The connection between
the devices can adopt a "cascade", a "star" or a "mixed" configuration,
between the first two.
