3.1.3 List of cables
The cables required for the installation of SL1 may vary depending on the type and quantity of devices to be installed; figure 17 shows the cables
needed for a typical installation; no cable is supplied with SL1.

3.2 Preparing the Electrical System
WARNING: 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.

[E] Radio aerial RG58 type shielded cable 20m(recommended less than 5m)
[F] Power supply line
3x1.5mm
2
cable
30m (note 1)
Note 1 A power supply cable longer than 30 m may be used provided it has a larger gauge, e.g. 3x2.5mm
2
, and that a safety grounding system
is provided near the automation unit.
Note 2 For the ESCbus, STOP and OPEN cables, there are no special contraindications to the use of a single cable that groups together multiple
connections; for example, the STOP and OPEN inputs can be connected to the KS1 selector switch using a single 4x0,5mm
2
cable.
With the exception of the power line, the rest of the system uses extra-
low voltage (approx. 24V); the wiring can therefore be done by personnel
that is not properly qualified, provided that all the instructions in this
manual are carefully observed.
After selecting the position of the various devices (refer to figure 1) you
can start preparing the conduits for the electrical cables connecting the
devices to the control unit.
The conduits are designed to protect the electrical cables and prevent
accidental breakage, which may be caused by the passage of vehicles,
for instance.
Although the connection of SL1 to the electrical mains is beyond the
scope of this manual, we wish to remind you that:
• The power supply line must be laid and connected by a qualified
professional electrician.
• Alternatively, have a suitably protected 16A "shuko" outlet
installed, where you can plug in SL1.
• The power supply line must be protected from short circuits
and ground leakage; a device must be provided to enable the
disconnection of the power supply during the installation and
maintenance of SL1 (the plug with outlet are suitable for this
purpose).
