                                What is the alternate part number for 17072

                                 Replacement is a A9MEM3210

                                Which KWH meter will measure Solar inputs with Modbus connections?

                                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.


                                What is the alternative code for 17072?


                                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 replacement for a 17072

                                 The replacement is a A9MEM3210.

                                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.

                                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.

                                Can the IEM3255 be monitored remotely via WiFi?

                                Unfortunately not. The IEM3255 is only capable of Modbus RTU.

                                However one our other unit can be used as a Modbus Gateway to allow communication to the device



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

                                Rogowski Coil CT's may require secondary lead length extension.

                                Metering & Power Monitoring

                                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.

                                How to change the wiring settings and CT ratio on the Acti 9 iEM3255 kWh Meter

                                Enter the configuration by pressing the ESC and OK button on the front of the Meter simultaneously. Enter the Password "0010"

                                The first parameter is Wiring - Change? to enter press OK and change the wiring setting as per the connection and save.

                                The next parameter will be CT & VT Ratio - Change? To enter press OK, change the CT Secondary and Primary as per the ratio of connected CT.

                                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.
