                                  Can you retrieve data from the A9MEM3155 modbus meter wireless using a Modbus to WiFi converter?

                                  We recommend to use  standard tested SE solution like using COM'X with Wifi dongle, which can be connected to iEM3155 over Modbus RTU and COM'X will sendthe data of meter over Wifi.

                                  Is the Acti 9 A9MEM3110 3 phase?

                                  Yes, the iEM3110 kWh meter with pulse output, is a 3 phase digital meter for direct connection up to 63Amps.

                                   Replacement is a A9MEM3210

                                  Do you have a Bacnet, NMI approved kilowatt hour meter with CT's?

                                  The part number for a Bacnet, NMI approved kilowatt-hour meter with CT's is a - A9MEM3265.


                                  What is the alternative code for 17072?


                                  Can the IEM3000 series read energy output from a Solar Panel?

                                  To be able to measure the energy out from a Solar Panel a meter needs to be able to do Four Quadrant Calculation.

                                  This means it is capable of Identification of imported and exported active and reactive energy allows you to monitor energy flow in both directions: delivered from the utility and produced on-site.

                                  In the iEM3000 series the following meters are capable of Four Quadrant Calculation.

                                  iEM31** range - iEM3135, iEM3155, iEM3165, and iEM3175
                                  iEM32** range - iEM3235, iEM3255, iEM3265, and iEM3275
                                  iEM33** range - iEM3335, iEM3355, iEM3365, and iEM3375
                                  iEM34** range - iEM3455, iEM3465, iEM3555, and iEM3565


                                  Power Meter Communication issue, registers not reading the correct value.

                                  The Power meters, based on the manufacturing location may have an offset. 

                                  In some meters the registers starts from Zero and some it is taken account from 1. So the published register list varies accordingly. 

                                  For Ex: If Register 2017 is for Frequency of the meters it will read 50 HZ. 
                                  But for the meter with offset the the Register 2016 will read 50HZ. 

                                  So it is good to check if the meter has got an Offset before proceeding with the communication issue.

                                  The New range of Acti9  A9MEM2150 for example only needs a N connection  - it does not require to pass the N current through it.

                                  Can Rogowski Coil Current Transformers (Rope Style CT's) Be Extended in the Field? How Far?

                                  The load may be farther from the meter than the standard 8' or 12' secondary lead lengths may reach.

                                  Schneider Rogowski Coil Current Transformers come in primary lengths of 12", 18", 24", or 36". 
                                  This measurement only applies to the primary length only.
                                  This is the length that the current transformer has to connect back to itself around a conductor or set of conductors of the load to be monitored.

                                  The lead length refers to the 8' or 12' that connects from the current transformer to the meter itself.

                                  It is sometimes difficult to get the meter mounting location within 8' or 12' from an appropriate location to install the current transformer on the load conductors.
                                  Because of this, one may need to extend the length of the secondary leads from the current transformers.

                                  Either the 8' or the 12' secondary lead length version of Schneider's Rogowski Coil (U018-xxx) Current Transformers may be extended to a maximum of 20' total lead length (to include the original lead length of either 8' or 12').
                                  The conductors used must be a standard 24 gauge twisted cable.

                                  What is the product code for the iEM2000 Acti9 230V 40A din rail mount energy monitor?

                                  The product code is A9MEM2000. Please see the attached datasheet for more information.

                                  On the PowerTag A9 F63 model, ref. A9MEM1562 if I try to be consistent with the flat cable position, the LED of the module is upwards. Should I twist the flat cable to have the LED down?

                                  This has no impact on the operation but to be consistent with the rest of the range we favor the Led down, and in this case, the flat cable is twisted.

                                  Peak Demand Values (iEM3455, iEM3465, iEM3555, iEM3565)

                                  In a nonvolatile memory, the power meter maintains a maximum operating demand value called peak demand. The peak is the highest value (absolute value) for each of these readings since the last reset.

                                  For information on how to set up, reset or read demand values from meter registers, please refer to attached iEM3000 User Manual.
