3 - PRELIMINARY CHECKS

Before installing the product, perform the following checks and in-
spections:
- make sure that the product fixing zone is not subject to flooding;
- check that the electricity supply line to which the product is to be
connected is suitably earthed and protected by an overload and dif-
ferential safety breaker device;
- the system power supply line must include a circuit breaker device
with a contact gap allowing complete disconnection in the conditions
specified by class III overvoltage;
- ensure that all the material used for installation complies with the
relevant regulatory standards;
- Please refer to Fig. 1 and in particular to the table with the nomen-
clature of the main parts to which reference will be made throughout
this manual.
- Please refer to Figs. 2 and 3 showing the overall dimensions and
the typical installation diagram of an automation system for road bar-
rier.
Before powering and starting up the product, check and verify the

4 - LIST OF CABLES REQUIRED

The cables required for connection of the various devices in a stan-
dard system are listed in the cables list table.
The cables used must be suitable for the type of installation; for

* If the power supply cable is more than 20 m long, it must be of larger gauge (3x2.5mm2) and a safety grounding system must be installed
near the automation unit.

following points:
- check that the manual movement of the barrier is smooth and free
from higher friction areas and jamming;
- check that the barrier bar, moved manually, is still balanced if incli-
ned to an angle of 45°..
Warnings:
- high acidity or salinity or nearby heat sources might cause the pro-
duct to malfunction;
- in case of extreme weather conditions (e.g. snow, ice, wide tempe-
rature variations or high temperatures), friction may increase, cau-
sing a corresponding rise in the force needed to operate the system;
example, an H03VV-F type cable is recommended for indoor appli-
cations, while H07RN-F is suitable for outdoor applications.
