DANGER
Tampering with the protections or any appliance modification could cause risks to users or
other exposed people.
The manufacturer does not assume any responsibility for direct or in direct damage to
people, things or animals following tampering with the protections.
On the Control Panel there’s the Main Switch (C1) also acting as Emergency Switch.
A Guard (optional) can be installed on the machine. This does not allow the operator to touch any moving
part of the machine during the test execution. The guard is formed by a wooden box and by an electronic
blocking device that disconnects the sieving unit whenever the box is opened during the test running.
Chapter 4 INSTALLATION INSTRUCTIONS
4.01
LOCATION
The equipment must be placed in an ideal position and environment for the use it has been conceived for (laboratory
use and protected from atmospheric agents) and that the machine is placed by a qualified operator.
ALLOWED TEMPERATURE: from +5°C to +40°C
ALLOWED RELATIVE HUMIDITY: from 30% to 70%
MAXIMUM HEIGHT OVER SEA LEVEL: 1000 m
GENERAL ADVICE
• The machine must be installed in an area which allows ease of access to all parts so that maintenance may be
carried out.
• Unauthorised people and objects which could be potential sources of danger must not be permitted in the area
surrounding the machine.
• Do not position the equipment near instruments or appliances which could produce vibrations.
4.02
TRANSPORTATION AND MOVEMENT
These instructions are applicable to the machine assemblers.
Ensure the equipment is correctly supported at the lifting point and that the machine does not slip.
Do not remain in direct line with the application of force and do not allow personnel where there are loads that cannot be
adequately supported by mechanical means.
4.03
ELECTRICAL CONNECTION
DANGER
Wiring of the electrical system must be carried out by qualified personnel.
Before wiring consult the electric plan linked to the instructions manual and the
registration plate on the machine for information regarding supply, frequency and
nominal current.
Connect the earthing system via the PE terminal (yellow-green) before any other
connection.
Apply a knife switch at the top of the connecting cable of the machine to the power
system.
The knife switch must be combined with a safety device against the overload with a
differential switch (safety switch).
The technical features of the safety device must be in accordance with the standards in
force in the country where the machine has been installed.
ELECTRIC TOLERANCES:
• Real voltage ± 10 % of the nominal one
• Frequency: ± 1 % of the nominal one in a continuous way
± 2 % of the nominal one for a short period
• The harmonic distortion of the sum from the second to the fifth harmonics not more than 10 % of the total voltage as
a real value between the conductors. A further distortion of 2% is accepted for the sum from the sixth to the thirtieth
harmonics of the real total value between the conductors.
• With reference to the voltage imbalance of the three-phase voltage, the inverted sequence component and the zero
sequence component must not be more than 2% of the direct sequence component of the voltage.
• The voltage pulses must not last more than 1,5 ms with an up/down time between 500 ms and 500 ms and a peak
value not higher than 200 % of the real value of the nominal tension.
