... When the CRD5490-Z is connected to AC lines, high voltage is present inside the box. Do not remove the protective cover from the CRD5490-Z when power is connected. The evaluation board connects directly to the AC power line and presents a serious risk of electric shock and can cause serious injury or death. Extreme caution needs to be exercised while handling this box ...

... The voltage sense resistor (R2) must be referenced to the same potential as the current sensor and CS5490 power supply (located either on the Line or Neutral). By design, the CRD5490-Z is referenced to the Line side after the fuse. To switch the sensor reference, Line and Neutral of both the load and the source could be switched, and the fuse should be placed on the line externally ...

... Reducing the value substantially reduces the capacitor's size. If size is not a factor, the more expensive buck design could be replaced with a simple voltage regulator. Figure 3 and Figure 4 show the two options evaluated for the CRD5490-Z design. Contact Cirrus Logic sales for assistance with a cost-reduced, regulator-only design. ...

... Once the USB communication has been established, the CS5490 serial port will report the Device Revision on the Connection tab. If the software is unable to establish a communication link with the CRD5490-Z board, a message is displayed indicating that the initial communication has failed. This message is displayed in Figure 8. ...
