Terminal Assignments and Connections
The subsequent diagram shows the assignment of the screw terminals.
We recommend to connect the Minus wire of the power supply to earth potential. GND
terminals 4, 6 and 12 are connected internally. Depending on input voltage and load of the
auxiliary voltage output, the total power consumption of the unit is about 200 mA.
