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.
• RESET: Meter without MID certification, with RESET function on ALL counters.
• For MID S configuration, the device name changes: the S letter is added (e.g. UEM40-2CS R70).

OVERVIEW

PICTURE/ABBILDEN/FIGURA/FIGURE/IMAGEN

Refer to picture B:

1. Neutral terminals
2. Metrological LED
3. Multifunction key
4. Backlight LCD display
5. S0 output terminals
6. Current and voltage terminals
7. Safety-sealing on each side (DO NOT REMOVE)

• The safety-sealings and the sealable terminal covers are included only with the MID or MID-S package.

For a correct seal closure, refer to picture C.

• SYMBOLS ON THE FRONT PANEL (EXAMPLE)

Refer to picture D:

• A. Meter constant (metrological LED)
• B. Base current (max current)
• C. Nominal voltage/frequency
• D. Wiring type, 1phase 2wires 1current
• E. Protection class
• F. Serial number
• G. MID approval symbols
• H. Type approval certification
• I. Accuracy class
• J. Working temperature
• K. Device name
• If the device is NO MID version, “Cl.1 EN 62053-21” will be shown instead of the G, H and I fields.

RS485 PORT

• The RS485 port allows to the management of the device by MODBUS RTU 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: 1.2.1 = 1 phase, 2 wires, 1 current
• 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.

SYMBOLS ON DISPLAY

Refer to picture G:

1. Imported (>), exported (<) real time or energy value
2. Capacitive or inductive value
3. Main area. In case of Code XX: metrological parameters corrupted, useless counter, to be returned to Manufacturer
4. S0 output active status
5. Measuring unit area
6. Partial counter value. Flashing=stopped counter
7. Communication active status

MEASUREMENTS

All total counters (kWh, kvarh, kVAh) can be associated with S0 output.

PAGE STRUCTURE

The device can display pages of energy counters, real time values, setup and information (refer to picture H). Some pages can be different or unavailable according to the device model/package. On any counter page, e.g. Exported active energy, press the key at least 2 s to display the corresponding partial counter. Press the key once to scroll pages. At the end of partial counters, the last counter page will be displayed, in this case Exported active energy.
NOTE: for MID S package, reactive energy counters are not displayed.

HOW TO START / STOP / RESET PARTIAL COUNTERS

Feature available only on partial counter pages.

To start, stop or reset a partial counter, refer to the following procedures shown in Picture I:

1. Procedure to start the displayed partial counter
2. Procedure to stop the displayed partial counter previously started
3. Procedure to reset the displayed partial counter

SETUP PAGES (picture J)

• Some setup pages can be unavailable according to the device package.

From any setup value page:

1. Press the key at least 2 s, the digit/item will start to flash.
2. Press the key once to change the value and confirm by pressing the key at least 2 s (repeat this procedure for the next digits, if any).

From partial counter reset page:

1. Press the key at least 2 s, a new page for confirmation will be displayed.
2. Press the key once to change the flashing value, Y to confirm the reset, N to cancel. Confirm by pressing the key at least 2 s.

• From energy counter reset page (only package RESET):
• ALL or 01…10 range are the possible selections:
• ALL=allows to reset all values relevant to a specific counter group. Each counter group can be identified by symbols on display ( P , </>). • 01…10=allows to reset the value relevant to a single counter. Each counter can be identified by symbols on display (</>, measure unit,).
• The first three pages are relevant to counter groups (ALL) and displayed according to the following order: partial counters / imported energy / exported energy

The next pages are relevant to single counters (01…10).

1. To select the group or the energy counter to be reset, press the key at least 2 s, the value will start to flash.
2. Press the key once to change the value.
3. Confirm by pressing the key at least 2 s, a new page for confirmation will be displayed.
4. Press the key once to change the flashing value, Y to confirm the reset, N to cancel. Confirm by pressing the key at least 2 s.

From setup exit page:

1. Press the key at least 2 s, a new page for confirmation will be displayed.
2. Press the key once to change the flashing value, Y to exit and save the settings, N to exit without saving, C to continue scrolling setup pages. Confirm by pressing the key at least 2 s.

INFO PAGES (picture H)

Up to 3 pages can be displayed to show details about:

1. Metrological part firmware release
2. Metrological part CRC
3. Communication type
