| | | A motor filter is required: - For long motor cables > 50 m (shielded) or > 100 m (unshielded) - If motors are used with an insulation system not suited for inverter operation. Lenze motors feature insulation with a high thermal reserve. Please note: - The frequency inverter is also loaded with approx. 12% of the motor filter rated current. - Shielded motor cables are required for a CE-typical installation Technical data for 150% overload | | - The typical mains voltage drop via the motor filter at rated current and rated frequency is 2-3% of the output voltage - The filters indicated are suitable for a mains voltage of up to 3 x 460 V ± 10% - The +UG and -UG terminals must be connected with the same cable cross-section as the motor cable. | | |
