This connection scheme is only an installation proposal and does not replace
professional planning and execution!
If the drive converter system operates at rated operation, the coolant circuit can be done
in a series connection. It should be noted that the temperature is analog measured in the
slave modules and an error signal is given digitally to the master. The water return flow
should always be attached at the master in order to display real temperatures.
The heat power dissipation for each unit size can be found in the technical data. The
resulting volume flow has to be in the recommended operating range of the temperature
difference (see diagram
). The relationships between heat power dissipation,
flow and temperature difference are shown in the diagram
.
