7.4 Electrical connection
Attention! Risk of material damage! A wrong connection (for instance inverting a phase with the neutral
or not connecting the neutral) DAMAGE IRREPARABLY: frequency converter, PLC, heating elements, motors.
Warning! Danger – electric current! The connections must be carried out by a qualified electrician.
7.3 Connection to compressed air supply
Fig. 9: Connection to compressed air supply
• Situated on the right hand side of the machine is the
filter/pressure regulator with outflow of condensation
together with quick fitting. Ensure that the
compressed air reaches the connecting area at least
7-8 bars and that the pressure is free from humidity
and has been suitably filtered. Always connect the
machine to the compressed air unit.
• Adjust the air pressure to 6,5 bars. Before
proceeding to any maintenance operation, it is
necessary to switch off machine, padlock it and also
disconnect the compressed air system by taking off
the fast snap-on fitting. The pneumatic plant does not
need any type of lubrication! The use of lubricant oils
can damage some of the pneumatic components.
Therefore the lubrication, in particular with some
types of oils, can seriously damage and compromise
the functioning of the machine. Never add lubricant
oils in the condensation collecting cup.
• To outflow the condensation it is sufficient to push
upwards the tap with the filter/ regulator under
pressure. The length and the inside diameter of the
pneumatic hoses must be proportioned for a correct
functioning of the G 500. Never supply the
G 500 with a pneumatic hose with 4 mm of internal
diameter.
Check that the voltage and the power frequency
available, correspond to those of the machine which are
shown on the identification plate fixed on the machine
frame. To connect the machine at 380-415-440 Volts,
use a cable with 5 wires (3 earth). The
three phases must be connected to L1,L2,L3, the neutral
to the N and earth to the connections PE (or 4 for the
USA version).
To connect use a 5 x 2,5 cable adequate for the total
power installed. To connect the machine at 220–240
Volts, use a cable with 4 wires (3 earth). The
three phases must be connected to L1,L2,L3, the earth to
the connections PE.
