CAUTION

This is a Class A product. In a residential environment, this equipment may cause radio interference. In this case, the user may have to take adequate countermeasures.

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 to the ring
• for a correct measurement, calibrate the Rogowski sensor by writing the calibration coefficient 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.

DIP – SWITCH SETTINGS

• The DIP-switch settings are read only at boot time. At each change, perform a restart.
• For use and settings via DIP-SWITCH, see the user manual available on the website on the web page dedicated to the product.

ELECTRICAL CONNECTIONS

CAUTION

• The installation of this appliance must only be carried out by qualified 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 configuration.
• The earth connection of the secondary of CTs with current, voltage, or rogowski output is possible on the negative terminal. In the case of rogowski sensors, the screen must always be connected to the negative terminal.
• 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.

FACTORY IP ADDRESS

• The default module IP address is static: 192. 168. 90. 101
• In the R-203-X-P version, the module is supplied without an IP address (0.0.0).

WEB SERVER

• To access the Web Server with the factory IP address above, use the following credentials: Username: admin; Password: admin

CAUTION

• DO NOT USE DEVICES WITH THE SAME IP ADDRESS IN THE SAME ETHERNET NETWORK.

ETHERNET CONNECTION RULES

For the Ethernet cabling between the devices, the use of the shielded CAT5 or CAT5e cable is required.

DAISY-CHAIN ETHERNET CONNECTION

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.

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.
