2. Establish RJ12-RJ12 cable connection between
control unit and Frequency Inverter.
As long as a diagnostics glass or a blind plug is
open, make sure that no dirt or moisture enters the
device.
3. After commissioning for regular operation,
reinsert
all diagnostics glasses or blind plugs
and pay
attention to
sealing
.

3.2.2 Connection of multiple devices to one parametrisation tool
In principle it is possible to access several frequency inverters via the
ParameterBox
or the
NORD CON software
. In the following example, communication is made via the parameterisation tool,
by tunnelling the protocols of the individual devices (max. 4) via the common system bus (CAN). The
following points must be noted:
1. Physical bus structure
Establish a CAN connection (system bus) between the devices
2. Parameterisation

3. Connect the parameterisation tool as usual via RS485 (e.g. via RJ12) to the
first
frequency
inverter.
Conditions / Restrictions:
Basically, all of the currently available frequency converters from NORD (SK 1x0E, SK 2xxE,
SK 5xxE) can communicate via a common system bus. When devices in the SK 5xxE model series
are incorporated, the framework conditions described in the manual for the device series concerned
must be noted.

In order to integrate an SK 2xxE-FDS frequency inverter into a system bus, the option slots M7, and if
necessary M5 must be equipped with the appropriate SYSS (M7) or SYSM (M5) plug connectors.
