2.3 - Typical system

Fig. 2 provides an example of an automation system, produced using
Nice components:
1 Gearmotor
2 Transmitter
3 Sensitive edge
4 Junction box
5 Control unit
6 Spiral cable
7 Flashing light
8 Photocell
9 Digital keyboard - Transponder reader - Key selector switch - Push button
panel
These parts are positioned according to a typical standard layout. With refer-
ence to Fig. 2, locate the approximate position for installation of each compo-
nent envisaged in the system.
Important – Before installation, prepare the electrical cables required for the
system, by referring to Fig. 2 and "Table 1 - Technical specifications of electri-
.
cal cables"
Caution! – When laying the ducting for routing the electrical cables and for the
cable entry point into the control unit housing, be aware that due to possible
deposits of water in the junction wells, the connection ducts might create con-
densate in the control unit, with consequent damage to the electronic circuits.

2.4 - Installation of the control unit

Proceed as follows when installing the control unit:
01. Open the control unit box: unscrew the screws as shown in Fig. 3-A /
Fig. 3-B;
02. Prepare the holes for routing the electrical cables for the accessories pro-
viding control and/or signalling functions. For this purpose, we recommend
using a special tool (e.g. hole cutter) on the marked positions at the bottom
of the box, also to ensure maintaining the level of IP protection. If neces-
sary, you can use the lateral cable entry points, but only by using suitable
ducting connections;
03. Secure the box. You can secure it in three ways:
a) directly onto the wall using the screws from inside the box (Fig. 4-A);
b) using the standard supports supplied (Fig. 4-B);
c) if the cable duct for routing the electrical cables is on the outside and
you need to fix the box at a maximum distance of 2 cm away from the wall
to allow the cables to be routed behind the control unit. NDA100 consists
of 4 spacers and a protective cover for introducing the cables inside the
control unit box. To install the unit using the (optional) accessory, refer to
Fig. 4-C.
04. At this point, you can make all the electrical connections: see Chapter 3.
To install the other devices used on the automated system, refer to the respec-
tive instruction manuals.
