2. HARDWARE OVERVIEW
The CRD5490-Z includes sensors (line voltage and current shunt), a power supply, a CS5490 power
monitor calculation engine, isolation, and an MCU. Figure 1 shows connections of each block.
Make sure that the power source is off before wiring any connection. The AC source is connected to plug IEC 60320
C14, and the AC load is connected to connector IEC 60320 C13. Make sure that all connectors are well connected
before the power source is turned on. Make sure all AC power line wiring is secured to the box and away from contact
before the power source is on.
