- Dimensioning procedure 15
- If you plan to connect one or more acsm1 drives to the same dc bus with acs355 drives take into account the following recommendations 15
- Instead of an external dc chopper you can use acsm1 s brake chopper which is independent of common dc operation acs355 has a brake chopper as well but in this case it cannot be used 15
- Prefer acsm1 as the supply unit because its supply diode bridge is over dimensioned 15
- Use external ac chokes in supply even though not recommended for acsm1 drives 15

- Acs355 dc fuse ratings 32
- If there is no overload the fuses can be dimensioned directly according to the power of the drive 32
- Technical data of common dc applications 32
- The fuse rating depends on the fuse type gg or ur and the temporary overload of the drive 32
- The recommended ratings rule of thumb are presented in the table below the voltage rating of the fuses is 690 v 32
- With gg fuses a rating one size smaller can be taken 32
- With ur fuses the rating is determined by the maximum instantaneous dc current because fuses work fast in practice the fuses have to be selected for a current about two times higher than the dc current calculated from the nominal power 32
