NOTE: This diagram only shows a possible application of the unit and should be considered merely as an example. Only an in-depth analy-
sis of the risks of the "Machine" gate and a proper evaluation of the end user requirements will be able to establish how many and which ele-
ments must be installed.
2.3) List of cables
The typical system shown in figure 2 also states the cables required for connection of the various devices, the specifications of which are
provided in table 1.
!
The cables used must be suitable for the type of installation; for example, an H03VV-F type cable is recommended
for indoor applications, while H07RN-F is suitable for outdoor applications.

Connection
A: Electrical power line
B: Flashing light with aerial
C: Electric lock
D: Photocells
E: Key-operated selector switch
F: Connection to the motors.
G: Connection to sensitive edge
Note 1: power supply cable longer than 30 m may be used provided it has a larger gauge, e.g. 3x2,5mm
tem is provided near the automation unit.
