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
further 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.
