1)
The specified voltages and the necessary impulse withstand/test voltages for the transformer
secondary windings with respect to ground. Since the transformers generally have temperature
evaluation systems in the windings, the specified test voltages are required for strengthened
insulation. If no control circuits have been installed in the windings, test voltages in accordance
with the basic insulation are sufficient.

3.5.8 Power Stack Adapter
The Power Stack Adapter (PSA) acts as the physical interface between the power unit and
the open-loop/closed-loop controller. This is where the galvanic isolation (electrical coupling
via light) between the power unit and the open-loop controller takes place. Data is exchanged
between the Power Stack Adapter and the Control Unit via the DRIVE-CLiQ high-speed serial
communication interface.
