2. Phoenix EEM-MB371-EIP 2907976:
This energy meter also allows the direct connection
of Rogowski coils. The energy meter must be con-
figured as a Modbus TCP slave.
3. Kostal Smart Energy Meter 10507524:
This requires the setting "Modbus TQ EM300-LR
(TCP)" in the web interface (parameter "Meter con-
figuration (Second)"). The energy meter also must
be configured as a Modbus TCP slave.
4. TQ Energy Manager EM 420-LLRR:
This requires the setting "Modbus TQ EM410/
EM420 (TCP)" in the web interface (parameter
"Meter configuration (Second)"). The energy meter
also must be configured as a Modbus TCP slave.
Installation and networking
Networking between the energy meter and the
charging station takes place via a direct connection
or via a switch / router.
The external energy meter can be placed in such a
way that only the external consumers are measured
or that the external consumers and the charging
station(s) are measured.
