Use components and materials with CE marking
which are compliant with the Low Voltage Directive
2014/35/EU and EMC Directive 2014/30/EU.
The power supply line for the automation must be
fitted with a multi-pole circuit breaker, with a suitable
tripping threshold, a contact opening distance of at
least 3 mm and a breaking capacity that complies
with current regulations.
The power supply for the automation must be fitted
with a 30 mA differential switch.

Check that the protective earthing system com-
plies with applicable regulations in the country of
installation.
The electrical cables of the automation system must
be of a size and insulation class that is compliant
with current legislation and laid in appropriate rigid
or flexible conduits, either above or below ground.
Use separate conduits for the power supply and the
12-24 V control devices / accessories cables.
In the case of a Master-Slave configuration, a cable
conduit has to be installed for the cables that connect
the two electronic boards.
Check buried cable plans to ensure that there are no
other electrical cables in proximity to the planned
digging/drilling locations to prevent the risk of
electrocution.
Check that there are no pipes in the vicinity as well.
The external electronic board must be housed in an
enclosure that has a minimum IP 44 protection rating
and fitted with a lock or another type of device to pre-
vent access by unauthorised persons. The enclosure
must be located in an accessible and non-hazardous
area and at least 30 cm from the ground. The cable

The conduit fittings and the cable glands must prevent
the entry of moisture, insects and small animals.
Protect extension connections using junction boxes
with an IP 67 protection rating or higher.
The overall length of the BUS cables must not exceed
100 m.
It is recommended to install a flashing light in a visible
position to indicate when it is moving.
The control accessories must be positioned in areas
that are always accessible and not dangerous for
the user. It is recommended to position the control
accessories within the field of view of the automation.
If an emergency stop button has been installed, it
must be EN13850 compliant.
Comply with the following heights from the ground:
- control accessories = minimum 150 cm
