WARNING
High Voltage Hazard
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. Make sure that the power source is off before wiring any
connection. 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.
Refer to additional warnings at the beginning of this document.
