Operation and operating the device
Internal power meter
The KOSTAL Smart Energy Meter can directly measure
up to 63 A per external wire. External transformers are
used for higher currents. If your device is connected to a
transformer, this can be set here.
To do this, activate “Use transformer” and set the trans-
former ratio. Common transformer ratios are provided in
the drop-down list. If the ratio is not included in the list,
click on “Other” and enter it manually. The primary cur-
rent may be in a range of 1 to 5000 and the secondary
current in a range of between 1 and 5.
Serial interface
Status information about the serial interfaces. This may
either be assigned freely or by a particular application,
the name of which is displayed here. The serial interface
is configured in the respective menus (e.g. Modbus set-
tings or inverter)
INFO
You will find a description of the
electrical connection for transformers
with an indirect measurement in the
KOSTAL Smart Energy Meter's instal-
lation manual.
