4.2.2 Supply Voltage
For voltage supply of the «EPOS4 EtherCAT Card», you may employ the EPOS4 Module’s power supply.
For details separate document «Hardware Reference» of the respective EPOS4 Module.
If you intend to use another source as power supply, we recommend to connect a TVS (transient voltage
suppressor) diode (D1) to the voltage supply line to protect against overvoltage resulting from voltage tran-
sients or brake energy feedback.
