Connector for redundant power supply

Device variants with 1 or 2 power supply units
There are devices variants with one power supply unit or with two power supply units. With
device variants with two power supply units, the 2nd power supply unit is also known as the
redundant power supply unit.
The connection is made using a 4-terminal plug-in terminal block to which two power supply
units can be connected (connected redundantly).
If two power supply units are connected, this is known as a redundant power supply.
Connect two power supplies as described below to achieve a correlation between the pin
assignment and LED display.
