Works Prior To Installation; Electrical Cables Preparation - Nice Maestro300 Instructions Et Avertissements Pour L'installation Et L'utilisation

––– STEP 4 –––

4.1 - WORKS PRIOR TO INSTALLATION

4.1.1 - Establish the position of the devices in the system
With reference to fig. 1 and fig. 5, locate the approximate position for
installation of each device envisaged in the system. The fig. 1 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 FL200 flashing indicator with built-in antenna
b) - 1 pair of PH200 photocells (made up of a TX and an RX)
c) - MAESTRO300C gearmotor with incorporated CL206 control unit
d) - MAESTRO300M gearmotor
e) - Closure stop (not supplied)
WARNING! - Some of these devices are optional and may not be
present in this package (see the Nice Home product catalogue).
WARNINGS:
• The gearmotors must be affixed to the column/wall, laterally to the
respective gate leaves;
• 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 space in 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 condi-
tion 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 implement 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.
• Place the ends of the ducting in the vicinity of the points provided for
affixing the devices.

A - Electric power line
B - FLASH flashing indicator output
C - Antenna cable
D - ECSbus devices cable
- STOP input
- SbS input
E - Gearmotor power supply cable
Note 1 - A power supply cable longer than 30m may be used provided it has a larger gauge (3 x 2.5mm
provided near the automation.
Note 2 - If the "ECSbus" cable is longer than 20m, up to 40 m, a larger gauge (2 x 1mm
Note 3 - These two cables may be replaced by a single 4 x 0.5 mm
CAUTION! – The cables used must be suited to the type of environment of the installation site.

4.2 - ELECTRICAL CABLES PREPARATION

To prepare all connection cables, proceed as follows.
a) - Observe fig. 5 to understand how the various devices should be
connected to the control unit and the terminals to be used for each
connection. Important - Only devices which support "ECSbus"
technology can be connected to the "ECSbus" terminal.
b) - Observe fig. 1 to understand how to position the electrical cables in
the environment. Then, draw a similar diagram on paper, adapting
it to the specific needs of your system. Note - This diagram will be
useful, both to guide the excavation of the routes for the cable duct-
ing, and for drawing up a complete list of the cables required.
c) - Read Table 2 to determine the type of cables to use; then use the
diagram you just drew and the environmental measurements to
determine the length of each individual cable. Caution! - Each cable
must not exceed the maximum length indicated in Table 2.
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.
