2.2.1 SK TU1 Profibus Module, Overview

The Profibus DP communication modules SK TU1-PBR or SK TU1-PBR-24V are used to connect
drive units of the SK 700E series to higher level automation systems via Profibus DP.

Note

If several SK 700E frequency inverters are installed immediately adjacent to each other
in a control cabinet, only SUB-D9 Profibus bus connectors with a 45° or 0° cable outlet
should be used to connect the Profibus technology unit.

In general, Profibus bus connectors with a 90° cable outlet should not be used, as due
to the contact of the bus connector housing with the cover of the frequency inverter, the
Profibus technology unit may be tilted.

If necessary, in case of any vibration and contact problems, the Profibus cables should
be fixed by means of SK 8 shield terminals and a shield bracket in the control cabinet.

Note

The cable shield must be connected to the functional earth

2

(usually the

electrically conducting mounting plate) in order to avoid EMC interference in the
device.

To achieve this, in the Profibus connector the shield must be connected to a large area
of the D-SUB connector and the functional earth.

In systems, electrical equipment is usually connected to a functional earth. This serves as a means to dissipate leakage and

interference currents in order to ensure EMC characteristics and must therefore be implemented according to high frequency
technology aspects.
