WARNING
Danger to life from electric shock in the event of a fault
In the event of a fault, devices connected to the mains may be live. There is a danger to life from
electric shock when making contact with live components.
► Always keep the mains connection freely accessible so you can disconnect it at any time.
The pump operates with a 48 VDC external power supply. The power supply and cable are available as
accessories (see chapter "Accessories").
It can also operate with an external power supply and a cable supplied by the customer with the re-
quired characteristics .
If the pump is connected to a main 48 VDC network (as defined by standard EN 61000-6), add a filter
and an overvoltage clipping system on the power line at the pump inlet: contact our service center. The
“-” pole of the 48 VDC is grounded internally.
