PREVENTIVE MEASURES AGAINST ELECTRICAL HAZARDS
The preventive measures provided for by the EN 60204-1 standard have been adopted against the danger of
direct and indirect contact and all the tests provided for by the above standard have been performed as
certified in the attachment to the EC declaration of conformity. All the tests provided for by the current
technical regulations have also been carried out for implementation of the EEC directive on EMC.
All the components are guaranteed by the manufacturers and each one is marked.
The machine is supplied with multi-pole cable with flexible wires in a PVC sheath type N 1 V V - K with low
gas emission.
The socket, interlocked by a switch, must be positioned at a height of approximately 130 cm from the floor
where there is no risk of knocking or damage.
At start-up the following MUST be checked:
-
correspondance between mains voltage and machine voltage
-
correct connection of the phases
-
correct motor rotation direction
The equipment and all other electrical components are installed in closed housings to prevent any DIRECT
contact with live parts; the following electrical current danger sign is affixed to the protective panel(s):
To protect against INDIRECT contacts, all the metal masses are connected via a yellow-green wire to the PE
terminal in the F.M. box to which the yellow-green wire of the multi-pole power supply cable is also
connected.
Via the plug-socket connection, this wire MUST guarantee electrical continuity between the machine and the
general earth system; the machine user will be responsible for ascertaining the suitability and efficiency of
the general system and accessory equipment necessary to cut off the power supply in the event of a failure.
To prevent the danger of faulty operation of the control circuit, one end of the transformer secondary circuit is
connected to earth; in addition, automatic switches are fitted both on the primary and secondary circuits.
The controls and signalling devices together with the symbols indicating their functions are fitted on a panel;
IP 54 protection rating is guaranteed overall by the characteristics of the individual electrical components and
by the seal fitted between the housing and the cover.
The machine as a whole is protected to IP 44.
The machine electrical equipment also includes a mushroom-headed emergency stop located on the front of
the machine.
