The following preset packages are available:
MID: MID certified meter, with reset function only on partial counters.
MID S: MID certified meter, with reset function only on partial counters,
without reactive energy counters on display.
NONE: Meter without MID certification, with reset function only on partial
counters.
RESET: Meter without MID certification, with RESET function on ALL counters.
For MID S package, the device name changes: the S letter is added (e.g. UEM63-4DS R70).

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
H. Accuracy class
I. Nominal voltage/frequency
J. Wiring type: =3phases 4wires 3currents
K. MID approval symbols
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.
