HF output filters

INFORMATION

Install output filters next to the corresponding inverter. Leave a ventilation space of at least 100 mm (3.94 in) below and above the output filter. No clearance is required on the sides.

• Limit the length of the cable between inverter and output filter to the absolute minimum needed. Maximum 1 m / 3 ft with unshielded cable, 10 m / 33 ft with shielded cable.
• Several motors can be connected to one output filter when operating a motor group from one inverter. The total value of the rated motor currents must not exceed the nominal throughput current of the output filter.
• Two identical output filters can be connected in parallel to one inverter output to double the nominal throughput current. To do this, connect all like connections to the output filters in parallel.
• Output filter connection V5 (with HF..-503) or 7 (with HF..-403) must not be connected when the inverter is operated with f_PWM = 4 or 8 kHz.
• No V_{DC link} connection is permitted for size 0XS units.
