2.4) Wiring list<br />
On the typical system of figure 3 the cables are specified for connection of the various devices; table 6 specifies the relative characteristics<br />
of the cables.<br />
! The cables used for connecting the various devices must be suitable for the type of installation: For example a cable<br />
type H03VV-F is re<strong>com</strong>mended if located indoors.<br />
Table 6: Wiring list<br />
Connection Cable type Maximum admissible length<br />
A: Electric power line 1 cable (3 x 1.5 mm²) 30 m (*)<br />
B: 12V Flashing Light 1 cable (2 x 1 mm²) 20 m<br />
C: Aerial 1 shielded cable (type RG58) 20 m (re<strong>com</strong>mended: Less than 5 m)<br />
D: Photocells 1 cable (2 x 0.5 mm²) 20 m<br />
E: Key-operated selector switch 1 cable (4 x 0.25 mm²) 20 m<br />
F: Sensitive edge 1 cable (2 x 0.25 mm²) 20 m<br />
Note: (*) if the power cable is longer than 30 m, a cable with a larger section is required, (e.g. 3 x 2,5 mm 2 ) and safety earthing is necessary<br />
in the vicinity of the automation.
