In the case of FC operation considerable electromagnetic interference occurs.
Here the limits specified in the pertinent standards and guidelines need to be
complied with under all circumstances by the installer. In order to reduce the
level of electromagnetic interference, shielded motor cables, shielded cable
feedthroughs, mains filters and EMC compliant ground connections are
required between frequency converter and pump.
In order to protect the pump, current limits in the frequency converter as a
function of the frequency must be taken into account.
Operation of the frequency converter requires the corresponding mains filter.
Note for maximum speeds that in the case of increased speeds and the
avail able maximum power, the maximum permissible pressure difference can-
not be attained.
