Page 64: Appendix 1: Questions & Answers
Q1. Can we use the other 5A CT’s (like 300/5) to directly connect to the input current terminals of PM-3133i series? No, because the input current is only mA size on PM-3133i series，definitely not to directly use other 5A CT’s to connect and apply （like100/5…），It could causes the fetal damages.
Page 65 (4) Confirm the RS-485 connection, make sure the D+/D- is right. (5) Confirm the RS-485 master have to provide the bias for PM-3133i series. Otherwise, the tM-SG4 or SG-785 should be added to provide the bias. All ICP DAS controllers and converters provide the bias.
Page 66 The CT of PM-3133i maximum range is 400A. If the target is more than 400A, we suggest the solution as follow. For example the target is to measure maximum 800A current. We can measure big CT output and set a CT Ratio.

For service voltage above 600 Vac, voltage transformers (PTs) are used to step down the voltage to a lower range that will work with a PM-3133i meter. Selecting a Transformer: Selecting the right voltage transformer is simple. Review the following considerations to determine the best fit for your application.
