A galvanic separation must fulfil the requirements for reinforced
insulation including creepage distances and clearances specified
in EN 60335.
5.4 Electrical connection - three-phase pumps, 11-22
kW
5.4.1 Preparation
Before connecting the E-pump to the mains, take the issues
illustrated in the figure below into consideration.

fuses, additional protection and protective earthing
5.4.2 Protection against electric shock - indirect contact
EN 61800-5-1 specifies that the pump must be stationary and
installed permanently when the leakage current is greater than 10
mA.
One of the following requirements must be fulfilled:
• A single protective earth conductor having a cross-sectional
area of minimum 10 mm

Warning
The user or the installer is responsible for the
installation of correct earthing and protection
according to local standards. All operations must be
carried out by qualified staff.
Warning
Never make any connections in the pump terminal
box unless all electric supply circuits have been
switched off for at least 5 minutes.
Note for instance that the signal relay may be
connected to an external supply which is still
connected when the mains supply is disconnected.
Warning
The surface of the terminal box may be above 70 °C
when the pump is operating.

Warning
The pump must be earthed in accordance with local
regulations.
As the leakage current of 11-22 kW motors is greater
than 10 mA, take extra precautions when earthing
these motors.
