F.4
CHECKS BEFORE INSTALLATION
Once removed from the packaging, check that the machine is free of abrasions or damaged
parts.
The materials that make up the packaging are recyclable.
Check that the mains voltage is compliant with the one required by the motor.
Check the diameter of the fittings to be connected to the pump.
HIGH TEMPERATURE HAZARD:
If the pumped fluid has a constant temperature above
60°C, the walls of the pump can reach temperatures that are dangerous for direct contact, so
it is necessary to provide appropriate signs or shielding.

ELECTRICAL CONNECTION
F.5.1
STANDARD CONFIGURATION WITH ELECTRICAL PANEL
These operations must be carried out at the end of the machine positioning and fixing operations, in order
to guarantee the correct functioning of the machine.
Electrical power supply connection
The connection of the machine to the mains must be carried out by specialised personnel, in compliance
with state-of-the-art technical practices and safety standards in force.
The machine must be connected to a protected earth circuit of proven efficiency.
If in doubt about the efficiency of the earth circuit, do not connect the machine.
The User is required to provide an adequate disconnect switch of the electrical line upstream of the
machine, as well as effective means of protection against surge currents and indirect contacts.
Effective means of protection against surge currents can be represented by the following elements
(correctly sized and adapted to the characteristics of use):
Fuses,
Automatic cut-outs,
Thermal-magnetic circuit breakers.
Effective means of protection against indirect contacts can be:
Residual current devices,
Fault sensors.
When connecting the machine to the mains, check:
That the data of the power supply correspond to the electrical data indicated in the wiring diagram
attached to the machine (an incorrect power supply voltage can damage the machine);
That the power supply network is equipped with an adequate grounding system.
The correct position and fixing of:
Guards,
Emergency button.
Connect the electrical panel of the machine using cables which are suitable for the current absorbed.
Use connection accessories (cable lugs, bolts, etc.) suitable for the cable to be connected and for the
current absorbed; these devices must be assembled according to the manufacturer's and accessories
instructions, as well as according to state-of-the-art technical practices.
Use wiring accessories (sheaths, junction boxes, etc.) that do not compromise the IP protection degree of
the electrical panel.
For a description of the controls, refer to the attached documentation.
F.5.2
CONFIGURATION WITHOUT ELECTRICAL PANEL (OPTIONAL)
The electrical panel and manual controls:
Must be installed at a height and in a position such as to allow easy access without effort for the
operator during use.
They must also be installed outside dangerous areas.
Useful information on this can be found in the standards EN60204-1 and EN894-4.
The electric control panel and the connection cables must comply with the regulations in force.
