Power supply
The bus coupler requires a supply voltage of 24 VDC (-15 %/+20 %) for operation.
The connection is made via the two upper terminal points labeled 24 V and 0 V. This power supply supplies the electronics of the bus coupler and the electronics of the EtherCAT Terminals via the E-bus. It is electrically isolated from the peripheral supply (Up) of the power contacts.
In order to guarantee the operation of the bus coupler and the terminal segment in all cases, the power supply must supply 2 A at 24 V.
Requirements for the 24 V power supply
In order to guarantee the operation of the Bus Coupler and the terminal segment in all cases, the power supply unit must supply 2.0 A at 24 V.
LEDs
If the power supply unit is connected correctly and the power supply is switched on, the two upper LEDs in the terminal prism are green. The left LED (Us) indicates the CPU supply. The right LED (Up) indicates the terminal supply. The other LEDs indicate the Terminal Bus status. A detailed description of the LEDs can be found in section "LED troubleshooting".
