SYMBOLS ON FRONT PANEL (EXAMPLE)
Refer to picture D:
A. Device name
B. Serial number
C. Data Matrix
D. Protection class
E. Meter constant (metrological LED)
F. Base current (max current)
G. Working temperature

L. Type approval certification
If the device is NO MID version, “Cl.1 EN 62053-21” will be shown instead of H, K and L fields.
TARIFF INPUT
The RS485 port allows to manage the device by MODBUS RTU/ASCII protocol. For device network connection, install a terminal resistance (RT=120…150 Ω) on the RS485 converter side and another one on the last device connected on the line. The maximum recommended distance for a connection is 1200m at 9600 bps. For longer distances, lower communication speed (bps), low-attenuation cables or signal repeaters are needed. Refer to picture E.
Default values: MODBUS RTU (8N1), 19200 bps
WIRING DIAGRAM
It is suggested to install a low power switch or some fuses on the voltage inputs for protection and in order to operate on the instrument without deactivating the plant.
Refer to picture F: 3.4.3 = 3 phases, 4 wires, 3 currents
Before instrument power ON, check if all connections are made in a proper way. Make sure that the voltage and current terminals are connected correctly. Moreover, make sure that low voltage ports, such as communication ports and/or SO ports, are connected to low voltage lines. These safety precautions may reduce the risk to damage the instrument in case of improper connections.
