| | | A motor filter is required: - For long motor cables > 100 - 200 m (shielded) or > 200 -400 m (unshielded) A sinusoidal filter is recommended: - If inverters are being used for the mains supply to systems which require a specific mains frequency - On UPS | | Please note: - The frequency inverter is also loaded with approx. 10% of the sinusoidal filter rated current - The typical mains voltage drop via the sinusoidal filter at rated current and rated frequency (fn = 50 Hz) is 7% of the inverter output voltage - The maximum permissible field frequency is 120 Hz - The filters indicated are suitable for a mains voltage of upto3x460V± 10% | | |
