NOTE
The wiring diagrams show the device complete with pulse output and RS485 interface.
In case of version without these features, the corresponding terminals must not be considered.
ATTENTION!
Aux. supply must be connected to terminals 20 and 21
Mounting instructions
Mounting of this equipment must be carried out just by skil-led personnel.
Please make sure that the data on the label (measuring voltage,
measuring current, extra supply voltage, frequency) correspond to the network on which the meter must be connected. In the wiring scrupulously respect the wiring diagram; an error in connection unavoidably leads to wrong measure-ments or damages to the meter.
When the meter is connected, conclude the mounting with the configuration as described in the user’s manual.

Alarm Diplay
If the meter has been programmed for relay output = alarm function (see point 1.7), in case of alarm intervention, the display blinks in order to detect the anomaly.
Pressing any of the front keys, the display stops blinking.
When the alarm is intervened, press several times key, until you display the alarm. page.
Auxiliary Supply
Terminals 20 and 21
Auxliary suppy: direct or alternating current electrical supply which is necessary for proper working of the device.
Please verify that the available supply voltage meets the one shown on the data label of the meter (voltage value and any frequency).
Where a double voltage is shown (for instance 80…265Vac/80…265Vdc) the meter can be fed with alternating voltage 80…265Vac or direct voltage 100…300Vdc.
In case of direct voltage supply please respect the shown polarities 20+ and 21.
