In both cases, the GND pin have no internal connection, and TP Pin is for factory calibration only. Connection 1: The power supply is on the receiver side. Only two connector pins are used. Connection 2: The power supply is on the CT side. Make sure you have a proper ground connection to prevent grounding noise. -4www.topstek.com TFC30P-CL420 V081007 10/7/2008
