Topstek True RMS Current Transducer TMQ80A..1000A-CL420 - 128 - www.topstek.com TMQ-CL420 V080530 7/1/2008 Application Connections TMQ-CL420 can be used with two types of connections. 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.
