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.
Note 1:
power supply cable longer than 30m may be used provided it has a larger gauge, e.g. 3x2,5mm
