3.2.1
Connection to the Electrical Mains
Although the connection of GD0 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.
• Have a suitably protected 16A “schuko” outlet installed, where
you can plug in GD0.
• Make sure that the power supply cable does not hang over mov-
ing parts or hazardous areas.
• The electric line must be grounded and protected against short
circuits; a bipolar disconnection device must also be present with
contact separation of at least 3mm, which allows the power sup-
ply to be disconnected during the installation and maintenance of
the GD0.
With the exception of the plug and the power cable, the rest of the sys-
tem 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 13) you
can start preparing the conduits for the electrical cables connecting the
devices to the control unit.
The shock-resistant conduits are designed to protect the electrical
cables and prevent accidental breakage.
Install any fixed control close to the door but away from moving parts and
at a height of 1.5m.
WARNING: the cables used must be suitable for the type of installation; for example, an H03VV-F type cable is recommended for indoor
applications.
Note 1:
For the PHOTO, 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 4x0.25mm
2
cable.

The cables required for the installation of GD0 may vary depending on the type and quantity of devices to be installed; figure 13 shows the cables
needed for a typical installation; no cable is supplied with GD0.
