4.PE Terminal: The PE terminal is connected directly to the Ocarina's heatsink or to the Castanet's two PE strips on its lower board. In the Ocarina, the heatsink serves as an EMI common plane. The PE terminal should be connected to the system's Protective Earth. Any other metallic parts (such as the chassis) of the assembly should be connected to the Protective Earth as well.
5.Under normal operating conditions, the PE trace carries no current. The only time these traces carry current is under abnormal conditions (such as when the device has become a potential shock or fire hazard while conducting external EMI interferences directly to ground). When connected properly the PE trace prevents these hazards from affecting the drive.
Follow these instructions to ensure safe and proper implementation. Failure to meet any of the
