ELECTRIC FEEDING
The electric feeding connection must be in conformance with the country legislation in which is used.
The electric feeding so must be maintained in conformance with the following technical prescriptions:
1.
the electric feeding must be always of type and have an intensity corresponding to the specifications indicated in the
machine plate. If excessive voltages are applied, some components will be damaged irreparably,
2.
a differential device must be foreseen coordinated with the protection circuit, respecting the legislation, the legislative
and regulation disposals in force in the installation country;
3.
the electric feeding cable outside the machine cover must be made pass in the spaces prepared from You and
adequately protected;
4.
if present the neutral conductor (N) before feeding the electric equipment, as for you its continuity must be guaranteed
(connected and available).
5.
before to feed the electric equipment, as for You must be guaranteed the continuity (connected and available) of the
green yellow conductor of the protection equipotential circuit.
PROTECTION DEVICE AGAINST THE OVERCURRENTS
The device is designed to resist to a symmetrical short circuit current of short duration not superior to 6kA. If the
acceptable assumed current of conditioned nominal short circuit, in the installation point results to be major to the showed
value, must be adequately limited.
Given that in the electric equipment supplied for the machine control and check, the electronic circuits aren't incorporated that
function with continue current, it is recommended to take adequate precautions to assure the protection against the in direct
contacts: in the protection field for the feeding automatic disconnection foresee APPROPRIATE DIFFERENTIAL
DEVICES. The differential device must be strongly resistant to the impulsive over voltages of atmospheric and operation
origin (cfr. EN 61008-1 last issues).
It is specified besides that:
1.
in the electric feeding sectioning device, in the head of the electric panel any nominal interruption power isn't
adapted because it is a plug/socket combination; besides it must be protected against the short circuits with a
protection device having nominal current not superior to the technical data,
2.
upstream the electric equipment feeding cable the protection device against the over currents must be installed and
maintained in conformance with the technical rules prescriptions.
ELECTRIC FEEDING SECTIONING DEVICE
The feeding sectioning device, as comparable from what described in the power circuits diagram delivered with the electric
equipment, is supplied for the machine feeding unique source.
In case of incompatibility between the net socket and the device plug change the socket with another type suitable from
maintenance personnel.
The feeding sectioning device allows separating (insulate) the machine electric equipment from the feeding, with the aim to
make possible the interventions fulfillment without electric shocks risks.
The sectioning device presents two possible positions:
OFF or "disconnected",
electric equipment
sectioned from the electric
feeding

ON or "connected", electric
equipment connected to the
electric feeding
