Current and Voltage. On the RS485 Modbus following measuring units are available:
Irms, Vrms, Watt, Var, Va, Vpk, Ipk, Frequency, Cosφ, Energy bidirectional and THD.
The device is fully congurable by RS485, DIN rail mounting, 4kV galvanic isolation for
Voltage input.
1 Safety guide lines
Read carefully the safety guidelines and programming instructions contained in
this manual before using/connecting the device. Disconnect power supply before
proceeding to hardware settings or electrical wirings. Only qualied personnel should
be allowed to use the device and/or service it and in accordance to technical data and
environmental conditions listed in this manual. Do not dispose electric tools together
with household waste material. In observance European Directive 2002/96/EC on
waste electrical and electronic equipment and its implementation in accordance with
national law, electric tools that have reached the end of their life must be collected
separately and returned to an environmentally compatible recycling facility.

6 Mounting
The Power Meter ENERGY-RS can be mounted in any position (see photo below),
horizontal or vertical mounting, horizontal or vertical through the two hooks for DIN
rail included in the box.
7 Conguration
Using a seriallinkRS485-USByou canconnecttheenergy-rs withtheinterface
program EnergyMeter-Programmer. This software allows to set the Modbus address,
baudrate, delay, the TV and TA ratio, to modify a lter in order to have fastest responce
time instead of a more stable measurement (lter range from 1-speed to 5-accuracy).
You can download the EnergyMeter-Programmer free of charge from Download Area
on our website .
A second way to program the device is by using the Modbus Register Map directly.

If you want to set the device by EnergyMeter-Programmer set the dips to 0. If you want
to set by RS485 directly, set the rst dip to 1 (up) then use the second dip for baudrate
setting ( 0 for 9600 or 1 for 38400). After the settings, please save the conguration

8 EnergyMeter-Programmer
The free interface program EnergyMeter-Programmer is the fastest way to congure
the device. The changes made to the program act on the register of the device.
To restore the default conguration, just press the button FACTORY DEFAULT.
Type of measure Allows the selection of the measure RMS or DC only to
dene the sign (positive or negative) of reading
Save on energy ash It is possible to activate the saving of the counters
directly on the device’s ash memory
Report of transformation In case you would use the TA and / or TV, you can dene
the transformation ratio for the current input and
voltage input, the default ratio is 1:1
Filter Allows to insert a lter on reading in order to get more
speed in responding (value 1) or a more stable and
accuratemeasurement ( value5).Bydefaultthevalue
is set to 2. You can choose between intermediate values
already set or manually enter the desired lter by
choosing the CUSTOM option from the menu.
In this case, you can set the following parameters:
ltering in DC, ltering in AC (default value 5 ), Frequency
measurement on Current channel
CAUTION : Magnetic elds of high intensity can vary the values measured by the
transformer. Avoid installation near permanent magnets, electromagnets or iron
masses that induce strong changes in the magnetic eld. If any irregularity, to reorient
or move the transformer in the area most appropriate.
