This document covers the following filter types: • RFI - filters on the input side, and ® • dU/dt - filters and sine - filters on the output side of the VACON NX AC drive. Safety notice WARNING: All internal components and component boards, with the exception of the galvanically separated input and output terminals are connected to high voltage when the AC drive is connected to the mains.
Page 5
The galvanically coupled interference may have to ® be filtered in order to achieve EMC compliance. The VACON NX range of AC drives contain an internal filter for bringing the drives into compliance with the standard (specifically IEC 61800- 3:2004).

2.1.1 General ® Table 1 shows the filters used to make the VACON NX range of AC drives comply with EN/IEC 61800-3 for the domestic and industrial environment, in case the basic drive does not comply. All enclosure sizes 4 - 9 comply with the requirements of EN/IEC 61800-3, ed 2 for the categories 1 and 2, the 690 V versions for category 3.
NX AC drives comply with the immunity requirements EN/IEC 61800-3; 2004, second environment as standard. Note that the filters RFI-0012-5-IP54 to RFI-0105-5-IP54 are designed to fit mechanically directly to the corresponding drive. All others are loose and must be connected to the drive separately.

Filter types vacon • 11 2.1.3 External RFI filter types The external filters must be mounted close to the input of the drive or drive system. Note that the cable layout must be such, that the maximum physical separation exists between the filter input and output cables.
Page 12
• 12 Filter types Installation recommendations: The motor cable must be kept as short as possible both inside and outside the enclosure. This means that the optimum location for the drive is close to the driven motor in wall mounted units or close to the cable conduit hole in enclosed units.

Filters are chosen so that their rated current > drive rated current. They will thermally withstand ® the same overload specifications as the drive. For VACON NX there is only one range of filters, suitable for the voltage range from 380 to 690 V. The filters can also be used at lower voltages, if required.

• 22 Filter types The S- type dU/dt filters are forced air cooled and require a 220 V AC power supply for their fans. The filter has a build-in thermal switch, which indicates if the filter temperature has exceeded the safe limits.
Page 23
Filter types vacon • 23 There are enclosure restrictions and details for selection and mounting when using UL listed accessories, IP00 dU/dt-filter models. These restrictions and details should be noted during the filter assembly. For details of drive selection and enclosure restrictions, see Table 15.
NOTE! The sine filters are designed for a switching frequency of 1.5 kHz for 690 V AC and 3.6 kHz for ® 500 V AC, which corresponds to the nominal switching frequency of VACON NX drives. It is safe to increase the switching frequency, but IT IS NOT ALLOWED TO DECREASE THIS VALUE below nominal, as there is a risk of overheating.
