WARNING
• Before positioning and starting the machine, read section “2. Sicurezze” carefully.
• After stating the machine, the power outlets are live, even without cables connected.
6.1 Grounding
WARNING
• The machine is not equipped with a residual current circuit breaker, and must not be connect-
ed to a grounding system.
• Protection against electric shock from indirect contacts is ensured by the "electrical separation" protec-
tion, with equipotential connection between all the masses of the machine.
• The limitation of the electrical circuit extension is essential for safety purposes; do not power systems
with a length greater than 200 meters.
• The power cables of the equipment must be equipped with the protective conductor (yellow-green cable)
to ensure the equipotential connection between the mass of the equipment and the mass of the machine;
this provision is not valid for double insulated or reinforced insulated equipment recognizable by the
symbol
.
• The cables must be suitable for the environment in which they are operated.
In case of temperatures below 5°C, PVC cables become rigid and the PVC insulation tends to be cut at
therstfold.
• Electrical separation protection is not suitable if the machine is intended to power complex systems, or
located in particular environments with a higher risk of electric shock.
In these cases, it is necessary to adopt the electrical safety measures required by current regulations.
Example:
It is possible to install a high sensitivity, 30mA, residual current circuit breaker and ground the machine
Neutral.Thisoperationmustbeperformedbyaqualiedelectricianoratanauthorisedservicecentre.
In this case, machine grounding is mandatory to ensure protection against indirect contacts by the resid-
ual current circuit breaker.
Connect the machine to a grounding system via a cable
using the grounding terminal (1).
