Power supply
The power supply is connected using a 4-pin plug-in terminal block.
The power supply can be connected redundantly. Both inputs are isolated. There is no
distribution of load. When a redundant power supply is used, the power supply unit with the
higher output voltage supplies the device alone. The power supply is connected over a high
resistance with the enclosure to allow an ungrounded set up. The two power supplies are
non-floating.
