Connect the Embedded PC as follows:
1. Open a spring-loaded terminal by slightly pushing with a screwdriver or a rod into the square opening
above the terminal.
2. The wire can now be inserted into the round terminal opening without any force.
3. The terminal closes automatically when the pressure is released, holding the wire safely and
permanently.

You have successfully connected the voltage source to the power supply terminal when the two upper
LEDs of the power supply terminal light up green.
The left LED (Us 24V) indicates the supply of the basic CPU module and terminal bus. The red LED (Up
24V) indicates the Bus Terminal supply via the power contacts.
