This operation must be performed by personnel who has been adequately trained on the risks arising from the
control equipment and the machine it is connected to. The personnel must be informed regarding the additional risks
coming from particular mechanical or electrical calibration procedures performed during this phase.
Only once COMMISSIONING is completed, the operators are allowed to operate the
The equipment is supplied complete with all the components, closed and tested. Therefore, the user is generally
only required to implement the wiring to the power supply line in accordance to the requirements of the technical
documentation and Chapter 2 TRANSPORT AND INSTALLATION.
Even though the single tests prescribed by law have been performed in the Varisco SpA
factory, the equipment installer is not exempt from the obligation to inspect it following
transport and installation!
The following verifications are required before starting-up the machine/system so as to prevent errors or
accidents due to the wiring phase of the components on board the machine:
VERIFICATIONS
the control panel, control push buttons, electrical wires and the protective sheaths must be intact;
the connections of all the external sources of energy, in particular the electrical connections, must be
correct and the power supply corresponds with the specified limits such as voltage, frequency, etc.;
the operational tests of the normal and emergency stop devices must have been performed.
STARTING-UP
The equipment is tested within the Manufacturer's premises before being shipped.
The following must be performed before the first start-up of the machine/system controlled by the
equipment:
check the sense of rotation of the motor, as follows:
1. Activate the main switch control lever of the contro panel, bringing it to the "I" position.
2. Turn the selector starter motor in position "1" and immediately after turn it to position "0" (ref. 4 figure 1).
3. Check that the sense of rotation of the motor is correct.
Should the sense of rotation of the motor not be correct, proceed as follows:
a) Activate the main switch control lever of the control panel, bringing it to the "0" position.
b) Disconnect the power supply to the control panel via the switch upstream the power supply line.
c) Invert any two of the three phases in the control panel line junction box (L1 - L2 - L3).
d) Close the electric cabinet.

The employer is legally obliged to keep the systems and safety devices in a good maintenance state so as to
guarantee safety.
Regular maintenance involves periodic verifications so as to guarantee the efficiency of the electrical equipment
and components.
The above is based on the assumption that maintenance is performed by qualified personnel who is very
familiar with the electrical equipment and knows how to intervene in routine operations as well as in the case of
faults or anomalies.
