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.
