ELECTRICAL CONNECTION INSTALLATION CHAPTER 3: ELECTRICAL INSTALLATION

3.6Electrical Connection Installation

Choose the diagram that best suits your application and maintain the CT polarity. Follow the outlined procedure to verify correct connection.

IMPORTANT: For PT connections only, short terminals 3 and 4.

Connect local ground to terminal 3. This protects the unit from spikes and transients.

•The meter and terminal module DSP3 are factory calibrated together; the serial numbers are matched on both. The DSP3 input module and the meter base MUST MATCH!

•Mismatching of the meter and DSP3 input module will cause inaccurate readings because calibration ratios are stored in the meter’s memory, not in the DSP3 input module.
