Digital input
Digital output
Pulse output
- The pulse output indicates the primary consumption with consideration of transformer ratios.
- It can be directly connected to a 24 V DC (< 30 V DC) input on a Zelio or Twido PLC.
- For other concentrators, if V DC / Rin > 15 mA, add a resistor Radd = (V DC / 0.01) – Rin Ω
Modbus / BACnet RS-485
LonWorks / M-Bus
The Lon and M-Bus ports are polarity-independent.
Power system wiring
F Fuses and disconnect switch Clearly label the device’s disconnect
circuit mechanism and install it within easy reach of the operator.
Fuses / circuit breakers must be:
- installed in accordance with all local and national electrical codes and standards, and
- rated for the installation voltage, available fault current, and sized for connected loads.
Fuse for neutral is required if the source neutral is not grounded.
1PH
1PH multiple load with N
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
Do not connect N’ to the load when setting the wiring type on the meter to
1PH4W Multi L-N.
Failure to follow these instructions will result in death or serious
injury.

Troubleshooting
| Code | Description | Possible solution |
|---|---|---|
| – | LCD display is not visible. | Check and adjust LCD contrast. |
| – | Push buttons do not function. | Restart the energy meter by powering off and |
powering on again.
101| Metering stops due to an EEPROM error. Press OK to display total energy
consumption.| Enter configuration mode and implement Reset Config.
102| Metering stops due to a lack of a calibration table. Press OK to display
total energy consumption.| Enter configuration mode and implement Reset
Config.
201| Metering continues. Mismatch between frequency settings and frequency
measurements.| Correct the frequency settings according to the nominal
frequency of the power system.
202| Metering continues. Mismatch between wiring settings and wiring inputs.|
Correct the wiring settings according to the wiring inputs.
203| Metering continues. Phase sequence reversed.| Check the wire connections
and correct the wiring settings if needed.
204| Metering continues. Total active energy negative due to incorrect voltage
and current conditions.| Check wire connections.
205| Metering continues. Date and Time have been reset due to a loss of
power.| Set the Date and Time.
206| Metering continues. Pulse is missing due to overload on energy pulse
output.| Check the energy pulse output settings.
207| Metering continues. Abnormal intemal clock function.| Restart the energy
meter by powering off and powering on again then reset the date and time.
