9.3 Mains supply

DANGER
Electric shock
Death or serious personal injury
- Use the recommended fuse size. See sections
31.1 Supply voltage
9.3.1 Single-phase supply voltage
• 1 x 200-240 V - 10 %/+ 10 %, 60 Hz, PE.
Check that the supply voltage and frequency correspond to the
values stated on the nameplate.
If you want to supply the motor through an IT
network, make sure that you have a suitable motor
variant. If you are in doubt, contact Grundfos.
The wires in the motor terminal box must be as short as possible.
Except from this is the separated grounding conductor which
must be so long that it is the last one to be disconnected in case
the cable is inadvertently pulled out of the cable entry.
