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.

The device is suitable for further use following a short-circuit failure. (Personnel and
equipment must not be put at risk).
