4.7 Electrical connection
DANGER
The connection to the ground must be made only by an electrical maintenance technician.
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.
ATTENTION
Adhere to the indications on the EC identification label.
ATTENTION
A disconnect switch must be installed on the machine that hosts the pump.
ATTENTION
The switch’s disconnect power must be ≤ 10 kA and the rated current In = 6 A.
ATTENTION
All the electrical components must be connected to the ground. This is valid both for the electrical components and for controller devices.
For this purp
ose, 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.
