11.2 Pumps with VFD

Observe the installation and operating instructions for the pump and the supplier
manual "BU 0180" for the VFD on

https://www.nord.com

. Pay attention to the

special VFD parameter settings for DMX.

VFD variants used with DMX pumps

The supplier offers a wide range of VFD variants. DMX pumps are available with the following
VFD variants:

•

VFD mounted on the pump motor

•

VFD with IP66 housing

•

VFD with potentiometer

•

VFD without braking resistor (BW)

•

VFD without ATEX approval.

11.2.1 Identification of pumps with VFD

Pumps with motors with PTC sensor and VFD are available in different variants which are shown
on the nameplate and explained in the type key. The last two letters of the type designation indi-
cate the VFD variant.
