Installation, connection and operation

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 connection cable between inverter and output filter to the absolutely necessary length. Maximum 1 m (3 ft) with unshielded cable, 10 m (33 ft) with shielded cable.
An unshielded motor line is sufficient when using an output filter. Note the following instructions when you use an output filter together with a shielded motor cable:

The maximum permitted length of the motor cable for operation without V_DC
link connection is 20 m (66 ft).

Operation with V_{DC link} connection is required if the motor cable is longer than 20 m (66 ft).

The rated through current of the output filter must be higher than or equal to the output current of the inverter. Note whether the projected output current of the inverter is 100% I_N (= rated output current) or 125% I_N (= continuous output current).
Several motors can be connected together to one output filter when operating a motor group from one inverter. The total value of the rated motor currents must not exceed the rated throughput current of the output filter.
It is possible to connect two output filters of the same type to one inverter output to increase the rated through current. To do this, connect all like connections to the output filters in parallel.
Considerable noise (magnetostriction) may occur in the output filter especially if operating with f_PWM = 4 kHz. In environments susceptible to noise, SEW-EURODRIVE recommends operation with f_PWM = 12 kHz (or 16 kHz) and V_{DC link} connection. Observe the notes regarding V_{DC link} connection.
When the inverter is operated with f_PWM = 4 or 8 kHz, the output filter connection V5 (with HF..-503) or 7 (with HF..-403) must not be connected (no V_{DC link} connection).
No V_{DC link} connection is permitted for size 0XS units.
