Frequently Asked Questions
The part number for a Bacnet, NMI approved kilowatt-hour meter with CT's is a - A9MEM3265.
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.
Yes, the iEM3110 kWh meter with pulse output, is a 3 phase digital meter for direct connection up to 63Amps.
Replacement is a A9MEM3210
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.
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
Rogowski Coil CT's may require secondary lead length extension.
U018 Rogowski Coil Current Transformers
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.
