Installation
The connection of the dU/dt and sine filters is shown in the figure below.
Figure 9. Filter connection
NOTE!
The maximum motor cable length for P-type dU/dt-filter is 100 m. In case of multiple cables,
the length is defined as a total length of the cables. Cabling capacitance and the switching current
grow as a cable length function. Therefore there is a risk of filter overheating, when long cabling
lengths are used. If the cable length is not sufficient enough, it is recommended to use a filter one
size larger or sine filters.
S-type dU/dt filters safe operation area as a function of the switching frequency of the drive and
motor cable length is shown in Chapter 3.3. Note that diagrams show values based on pre-defined
cable capacitance. The values should be scaled in accordance with the actual capacitance of the
cable. In case of multiple cables the capacitance is defined as a sum of the cable capacitances.
NOTE!
Cooling of P-type dU/dt filters is based on natural air convection (AN). Therefore, proper
ventilation and placement inside the enclosure must be ensured during assembly. Suitability for
base or wall mounting is show in Table 17.
