ROGOWSKI SENSOR
The Rogowski sensor is a ring-shaped device designed for measuring AC, impulsive or complex waveforms.
For its correct use:
- wrap the ring on the conductor so that the arrow symbol on the ring points in the same direction as the current in the conductor
- make sure the connections are made correctly
- for a more precise measurement, the conductor wire must be placed in a central position with respect to the ring
- for a correct measurement, calibrate the Rogowski sensor by writing the calibration coefcient in the corresponding
Modbus register (see the user manual).
Example: if the sensor is supplied with a characteristic of 90 mV / 1000 A, on the calibration register corresponding to the
phase in which the Rogowski sensor is applied, the value to be set is: 1000/ (90 · 10) = 1.11
NOTE ON ACCURACY: The product has a nominal accuracy of 0.5%. The total accuracy is the sum between the accuracy
of the device and the accuracy of the Rogowski sensor connected to it.

ELECTRICAL CONNECTIONS
The installation of this appliance must only be carried out by qualied personnel.
Check that the device plate data (measurement voltage, auxiliary power supply voltage, measurement current, frequency)
match the actual data of the network to which the instrument is connected. In the wiring, strictly observe the insertion
diagram; inaccuracy in the connections inevitably causes false measurements or damage to the instrument.
Once the instrument is connected, complete the installation with the device conguration.
The ground connection of the TA sensors is possible with connection on the negative cable.
Current measurement is only possible using current transformers.
It is advisable to insert a slow-blow 1 A fuse as indicated in the diagrams below.

ETHERNET CONNECTION RULES
PRODUCT ID CODE
For the Ethernet cabling between the devices, the use of the shielded CAT5 or CAT5e cable is required.
DAISY-CHAIN ETHERNET CONNECTION (ONLY R-203-2)
CAUTION
IT IS NOT ALLOWED TO CREATE LOOPS WITH ETHERNET CABLES
Using the daisy-chain connection it is not necessary to use switches to connect the devices.
The following examples show the correct connections.
There must be no loops in the Ethernet cabling, otherwise the communication will not work. The modules and switches
must be connected eliminating any loops. The following examples show the incorrect connections.
The LAN fault-bypass function allows you to keep the connection between the two Ethernet ports of the device ON, in the
event of a power failure. If a device turns off, the chain is not interrupted and the devices downstream of the switched-off
one will still be accessible. This function has a limited duration: the connection remains active for a few days, typically 4.
The fault-bypass function requires that the sum of the lengths of the two cables connected to the switched off module is less
than 100m.
