The unmounted connectors and the power and signals cables must have suitable thickness with
regard to the absorption of the machine and type in accordance with regulations in force. They
can be ordered separately (see Paragraph 7.1).
The pump must be installed in an industrial environment in compliance with prevailing law.
In order to prevent dangers of electrocution due to direct or indirect contact with the live parts,
the electrical power supply line must be adequately protected with a specific breaker switch with
0.03 Ampere tripping threshold and max tripping time of 1 second.
DANGER:
check the correspondence between the electrical power supply of the pump and that of
the machine / electrical power supply system (by means of the electrical specifications
declared on the CE Tag applied on the side of the pump reservoir).
DANGER:
a disconnect switch must be installed on the machine that hosts the pump.
DANGER:
the switch’s disconnect power must be ≤ 10 kA and the rated current In = 6 A.

DANGER:
all the electrical components must be connected to the ground. This is valid both for the
electrical components and for controller devices. For this purpose, ensure that the
ground wire is connected directly. For safety reasons, the ground cable must be about
100 mm longer than the phase wires. In the event of accidental disconnection of the
cable, the ground terminal must be the last to disconnect.
