Frequently Asked Questions
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.
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.
The New range of Acti9 A9MEM2150 for example only needs a N connection - it does not require to pass the N current through it.
Yes, the iEM3110 kWh meter with pulse output, is a 3 phase digital meter for direct connection up to 63Amps.
Replacement is a A9MEM3210
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.
The product code is A9MEM2000. Please see the attached datasheet for more information.
The part number for a Bacnet, NMI approved kilowatt-hour meter with CT's is a - A9MEM3265.
