1) The interference suppression filter is used to remove conducted interference in the main circuit. The field
-conducted
emissions meet radio suppression level B. The filter selection applies under standard conditions: 10 starts per hour,
start time 4 s at 300% I

Types of coordination
The type of coordination according to which the motor feeder with soft starter is mounted
depends on the application-specific requirements. Normally, fuseless mounting (combination
of motor starter protector and soft starter) is sufficient. If type of coordination 2 needs to be
fulfilled, semiconductor fuses must be fitted in the motor feeder.
Type of coordination 1 in accordance with IEC 60947
-4-1:
The device is defective following a short
-circuit failure and therefore unsuitable for fur-
ther use (personnel and equipment must not be put at risk).
Type of coordination 2 in accordance with IEC 60947
-4-1:
The device is suitable for further use following a short
-circuit failure (personnel and
equipment must not be put at risk)
.
The type of coordination only refers to soft starters in conjunction with the stipulated
protective device (motor starter protector / fuse), not to additional components in the
feeder.
