NOTICE

All of the information that is relevant for a safe start-up of this module and the frequency inverter is only available
under these conditions.

Validity of the documents

Scope of supply

1 x Module SK CU4-POL
1 x System bus cable set grey / black
1 x 24 VDC cable set brown / blue
2 x Connecting screws M4 x 20, cross-head

Field of use

Internal interface for connecting a decentralised frequency inverter (SK 180E … SK 2xxE) to a

ATTENTION

Derating

Depending on the installation location of the module (SK 180E, SK 190E or SK 2xxE), the operating mode (S1,
S3 ...) and the installation type (wall-mounting, motor -mounting) of the frequency inverter as well as the type of

permissible am
