• Maximum motor cable length for NOCH0xxx-6x filters (cumulative for several parallel-connected motors): NOCH0016-60/62 150 m NOCH0030-60/62 (can be increased to 300 m by NOCH0070-60/62 connecting two filters in series) NOCH0120-62 NOCH0016-65 50 m NOCH0030-65 (can be increased to 100 m by NOCH0070-65 connecting two filters in series) NOCH0120-65...
• NOCH0xxx-6x filters are designed to cool by natural convection, thus the following free space requirements apply: Wall-mounted filter units: 300 mm on each free side. Exception: 500 mm above the filter if installed below the drive. Floor-mounted filter units: 300 mm on each free side.
Ambient conditions, storage Ambient storage conditions refer to the conditions du/dt filters are subjected to during storage in the protective package. ° Temperature: -40 to +70 Relative humidity: Less than 95%, no condensation allowed Atmospheric pressure: 70 to 106 kPa Vibration: AOCH0xxx-70: Max 1 mm (5 to 13.2 Hz), max 7 m/s (13.2 to 100 Hz) sinusoidal...
