NOTICE

Validity of the documents

This document is only valid in combination with the operating instructions for the relevant frequency inverter.

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.

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

POWERLINK field bus. It is connected to the inverter via the system bus, and can communicate

directly with up to 4 frequency inverters. 2 digital inputs are available.
