The overpressure disconnector can extend the capacitor by 8 mm. Therefore
sufficient space must be left above the terminals when mounting the capacitors.
The capacitors are connected in delta. In NSIN1380-6, two capacitors are connected
in parallel. The minimum cross-sectional area of capacitor wiring is as follows:
NSIN0210-6, NSIN0315-6, NSIN0485-6
See the chapter
The filters are cooled by a fan; the airflow must be directed through the choke unit,
and recirculation prevented e.g. with an air baffle. It must be made sure that there is
enough cooling air available and that the hot air can freely escape the filter
enclosure or cubicle.
The cooling fan must be provided with a 230 V AC supply.
Motor cabling
The maximum cable length between the drive and the filter is 5 metres. If the
required length exceeds 5 metres, du/dt filters must be used at the drive output. The
cable length between the filter and the motor is not restricted. All other cabling
requirements for the ACS800 also apply to the filters. See the Hardware Manual of
the drive.
