PM motor
For the PM motor, see the cable sizing table below. This table is
given for reference only, and it must under no circumstances be
used instead of the current local standards.

The value of the rated current and the motor cable cross-
sections are given for reference only. As a reminder, the motor
rated current permitted varies according to the switching
frequency and the temperature.
(2)
For 110 kW and higher power, there are two wires on each
phase, so six wires are used in total.

170M: Bussmann fuses.
(4)
The power cable cross-sections are given for reference only
for a current corresponding to the value of the Ico current at 3
kHz, a maximum length of 50 m, output frequency less than
100 Hz and an ambient temperature of 40 °C. We recommend
screened multi-core power cables. See fig. 20. The values
supplied are typical values.

The PE conductor cross-section must be not less than half of
the associated phase conductor cross-section assuming that
the same material is used.
AC motor
For BMS systems supplied with AC motor, see recommendations
from VFD manufacturer.
Software
The Grundfos BMS hs pump is supplied with the required
software configuration file, if the VFD is supplied by Grundfos.
You can find the number of the software configuration file on the
small sticker placed below the control panel in the control cabinet
for the frequency converter.
See also the configuration reference guide supplied with the
product.
Do not change any settings without guidance from
Grundfos Service.
