Introduction to the guide
What this chapter contains
This chapter describes the contents of this guide. It also contains information on the
applicability, safety, target audience and the purpose of this guide.
Applicability
This guide applies to ACS355 drive modules connected to a common DC bus.
Safety instructions
Follow all safety instructions delivered with the drive.
Read the complete safety instructions before you install, commission, or use the
drive. The complete safety instructions are given at the beginning of the User’s
manual.
In addition:
• follow all the safety instructions given in section Limitations on page 13
• make sure that you set parameter 2020 BRAKE CHOPPER as instructed in
section Obligatory parameter settings on page 23.
Target audience
This guide is intended for people who plan the installation, install, commission, use
and service ACS355 drive modules connected to a common DC bus. Read the
User’s manual before working on the drive.
You are expected to know the standard electrical wiring practices, electronic
components, and electrical schematic symbols.

- 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
