Children should be supervised to ensure that they do not play with the appliance.
1.2.3 General safety rules
WARNING:
Always keep the work area clean.
Pay attention to the risks presented by gas and vapors in the work area.
Always bear in mind the risk of drowning, electrical accidents, and burn injuries.
DANGER: Electrical hazard
Avoid all electric dangers; pay attention to the risk of electric shock or electric arcs
Unintended rotation of motors creates voltage and can charge the unit, resulting in death,
serious injury, or equipment damage. Ensure that motors are blocked to prevent unintended
rotation.
Magnetic fields
The removal or installation of the rotor in the motor casing generates a strong magnetic field.
DANGER: Magnetic hazard
The magnetic field may be dangerous for anyone wearing peacemakers, or any other medical
devices sensitive to magnetic fields.

4.1.1 Installation area
DANGER: Potentially explosive atmosphere hazard
The operation of the unit in environments with potentially explosive atmospheres or with
combustible dusts (e.g.: wood dust, flour, sugars and grains) is strictly forbidden.
WARNING:
Always wear personal protective equipment
Always use suitable working tools
When selecting the place of installation and connecting the unit to the hydraulic and electric
power supplies, strictly comply with current regulations.
Ensure that the input protection rating of the unit (IP 55, NEMA Type 1) is suitable for the
installation environment.
CAUTION:
Input protection: to ensure the IP55 (NEMA type 1) protection index make sure that the unit is
closed correctly.
Before opening the terminal box cover, check that there is no liquid in the unit
Make sure that all unused cable glands and cable holes are correctly sealed
Make sure that the plastic cover is correctly closed
Do not leave the terminal box without cover: risk of damage due to contamination.
4.1.2 Unit installation

4.2 Electrical Installation
DANGER: Electrical hazard
The connection to the electric power supply must be completed by an electrician possessing the
technical-professional requirements outlined in the current regulations.
4.2.1 Electrical requirements
Local directives prevail on the specific requirements indicated below.
Electrical connection checklist
Check that the following requirements are met:
The electrical leads are protected from high temperature, vibrations, and collisions.
The current type and voltage of mains connection must correspond to the specifications on
the data plate on the pump.
The power supply line is provided with:
- High sensitivity earth leakage circuit breaker (30 mA) [RCD residual current device] suitable
for fault currents to the earth, with pushbutton AC or DC components (single-phase
version), or pushbutton AC or DC and direct current components (three-phase version)
- A mains isolator switch with a contact gap of at least 3 mm.
The electrical control panel checklist
NOTICE:
The control panel must match the ratings of the electric pump. Inappropriate combinations do not
guarantee the protection of the unit.
Check that the following requirements are met:
The control panel must protect the pump against short-circuit. A time lag fuse or a circuit
breaker (Type C model is suggested) can be used to protect the pump.
The pump hasbuilt in overload and thermal protection, no additional overload protection is required.
DANGER: Electrical hazard
Before starting work on the unit, make sure that the unit and the control panel are isolated from
the power supply and cannot be energized.
Grounding (earthing)
DANGER: Electrical hazard
Always connect the external protection conductor to the ground terminal before attempting to
make any other electrical connections
Connect all the electric accessories of the pump and the motor to the ground, making sure that
the connections are completed correctly
Check that the protection conductor (ground) is longer than the phase conductors; in case of
accidental disconnection of the power supply conductor, the protection conductor (ground)
must be the last one to detach itself from the terminal.
Use a cable with several strands to reduce electric noise.
4.2.2 Wire types and ratings
All cables must comply with local and national standards in terms of section and ambient
temperature
Use cables with minimum heat resistance +70°C (158°F); to ensure compliance with UL
(Underwriters Laboratories) regulations, all power supply connections must be completed
using the following types of copper cables with minimum resistance +75°C: THW, THWN
Cables must never enter into contact with the motor body, the pump and the piping.
The wires connected to the power supply terminals and the fault signal relay (NO, C) must be
separated from the others by means of reinforced insulation.
