8- ELECTRICAL CONNECTIONS
Provide a manual disconnector near the machine to be able to cut it off the power line during maintenance
operations.
Provide a fuse or magnetothermal cutoff switch to protect the machine.
The power cables must be sized taking into account the maximum machine absorption value, shown on the
label and in the technical manual; however, they should not be less than 0.75 sq.mm.
Check that the voltage and frequency of the power mains is 230V - 50Hz.
Before carrying out any machine servicing, make sure that the main power supply is switched off and that it
can not be turned back on unintentionally. Before opening the electrical box, wait at least 60 seconds after
disconnecting the power supply. In any case, after opening the electrical box, before touching the board or the
electrical connections, check with a tester (set to direct V) that the voltage at capacitor ends is less than 38V
(test points are provided on the board for this specific purpose). Stop servicing the machine if the measured
voltage is higher than 38V.
The unit has hydraulic and electrical connections on opposite
sides; if the electrical pre-setting has been provided on the
same side as the hydraulic connections, it is possible to reach
the opposite side by routing the wires over the back panel; the
wires, routed in this way, will then be covered by the covering
cabinet cross piece.
