1 APPLICATION
ND30PNET meter is a digital programmable instrument designed to measure network
parameters of single-phase 2-wire and three-phase 3 and 4-wire balanced and unbalanced
systems. The measured values are displayed on a color graphic screen TFT 3.5” with a
resolution of 320 x 240 pixels. The meter enables the control and optimization of power
electronic devices, systems and industrial installations.
It provides measurement of: RMS voltage and current, active, reactive and apparent power,
active, reactive and apparent energy, power factor, frequency, harmonic currents and voltages
/up to 51st/, THD of current and voltage, average active and apparent power, P Demand,
S Demand, averaged current
I Demand /15, 30 or 60 minutes/. Voltages and currents are multiplied by given current and
voltage transformer ratios of measuring transformers. Indications of power and energy include
the values of programmed ratios. The values of the measured quantities can be transmitted to
the host system through RS485 interface or Ethernet / Profinet interface, relay outputs signal
overruns of the selected parameters, programmable analog output maps the assigned
parameter. Temperature inputs can be used to control the temperature of the windings of
transformers, motors.
The meter has a galvanic separation between the individual blocks of:
- power supply,
- voltage inputs,
- current inputs,
- RS485 Interface,
- Ethernet/Profinet interface,
- alarm outputs,
- analog output,
- Pt100 sensor input.

3 BASIC REQUIREMENTS, OPERATIONAL SAFETY
In terms of operational safety the meter meets the requirements of EN 61010-1.
Safety precautions:
The meter installation and connection should be performed by qualified personnel.
All available protection requirements must be taken into consideration.
Prior to turning on the meter verify the connections.
Prior to removing the meter housing, always turn the supply off and disconnect the
measurement circuits.
Removal of the meter housing during the warranty period voids the warranty.
The meter meets the requirements for electromagnetic compatibility in industrial
environment.
A switch or a circuit-breaker should be installed in the building or facility. It should be
located near the device, easily accessible to the operator and properly marked.

4 INSTALLATION
The meter is adapted to be fixed to the panel by means of mounting brackets, according
to fig. 1. The housing of the meter is made of self-extinguishing plastic.
Fig.2. Meter fixing
Housing dimensions 96 x 96 x 77 mm, mounting hole dimensions 92.5 x 92.5 mm. Outside the
meter there are screw terminal strips that allow the connection of external wires with diameter up
to 2.5 mm2..

5 DESCRIPTION OF THE INSTRUMENT
5.1 Current inputs
All current inputs are galvanically isolated (internal current transformers). The meter is adapted
for use with external current transformers / 1 A or 5 A /. Displayed values of the current and the
derived quantities are automatically calculated by the value of the introduced external
transformer ratio.
5.2 Voltage inputs
All voltage inputs are galvanically isolated (internal voltage transformers). Quantities at voltage
inputs are automatically calculated by the amount of introduced ratio of the external voltage
transformer. Voltage inputs are defined in the order as 3x57.7/100 V, 3x230/400V or
3x110/190V; 3x400/690 V.
5.3 External connections diagram
External connections are shown in Figure 4.
