Multi-tier drive line-up

The following points must be observed for the arrangement of a multi-tier drive line-up:

● The individual wires must be shielded, and the shield must be attached at both ends.

● The DC link is continued outside the components using the DC link adapter (for

● The distance between the tiers of modules primarily depends on the wiring, the cable

● The inlet temperature of the air sucked in for cooling the module must not exceed 40° C

Operating faults due to incorrectly laid cables

Particularly with regard to satisfying the EMC requirements, signal cables should not be laid

parallel to power cables.

Arrangement of the components for infeed of the DC link voltage from the right

If the infeed is on the right-hand side of the drive line-up (e.g. in a multi-tier configuration),

the rules described in Chapter Single-tier drive line-up (Page 699) apply in the inverse

• Arrangement of the Motor Modules depending on their power, starting with the highest

• DC link components, such as Braking Modules, at the end of the tier
