8 WG20 Instructions
3.1.1
Operating Limits
Chapter 6 "Technical Characteristics" provides the fundamental data
needed to determine whether all the WG20 components are suitable for
the intended application.
In general, WG20 is suitable for the automation of gates featuring leaves
up to 4,5m wide, weighing up to 400 kg, with opening angle of up to
130° for residential applications.
The shape of the gate and the climatic conditions (e.g. presence of
strong wind) may reduce these maximum limits. In this case it is
necessary to measure the torque needed to move the leaves under the
worst conditions, and to compare it to the data provided in the technical
characteristics chart for the WG20 gearmotor.
3.1.2
Tools and Materials
Make sure you have all the tools and materials needed to install
the system; make sure that they are in good condition and
serviceable according to current safety standards. See examples
in Figure 13.
3.1.3
List of Cables
The cables required for the installation of WG20 may vary depending on the type and quantity of devices to be installed; figure 14 shows the cables
needed for a typical installation; no cable is supplied with WG20.

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.
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.
