Configuration
The Auxiliary Power Supply Module is connected on the plant side to a voltage
corresponding to the respective rated device voltage.
The standard version contains the following components:
● Fuse switch disconnector with fuse monitoring for external evaluation
● Supply of auxiliary busbar system with 3 auxiliary voltages:
● Customer terminal blocks 230 V 1 AC and 380 V 2 AC, e.g. for supplying power to a
● Transformer with output voltage 230 V 1 AC
● SITOP power supply 24 V DC
● 6-pole auxiliary current busbar for 24 V DC supply and fan power supply, including the
● PE busbar, nickel-plated (60 x 10 mm), including jumper for looping through to the next
Note
The configuration example of the Auxiliary Power Supply Module is used to illustrate the
positioning of the factory-fitted components. They show the maximum possible configuration
of the modules, which contain all options that can be ordered.
