1 APPLICATION
The ND30IoT meter is a programmable digital instrument designed for the measurement
of 1-phase 2-wire and 3-phase 3 and 4-wire power network parameters in balanced or
unbalanced systems. The measured values are displayed on a 3,5’’ TFT full-color screen,
resolution: 320 x 240 pixel. The meter enables control and optimization of the power electronic
devices, systems and industrial installations.
The meter provides measurement of: RMS of voltage and current, active, reactive and apparent
power, active, reactive and apparent energy, power factors, frequency, the harmonics of current
and voltage /up to 51st/, THD of voltage and current, averaged active and apparent power P
Demand, S Demand, averaged current I Demand /15, 30 or 60 minutes/. Voltages and currents
are multiplied by given voltage and current ratios of the measuring transformers. Power and
energy indications take into account all programmed ratio values. The value of each measured
value can be transmitted to the master system via the RS-485 or Ethernet interface. Three relay
outputs signal the overflow of the chosen value and the programmable analog output maps the
assigned parameter. The temperature inputs can be used to control the temperature of the
transformers windings, motors.
There is a galvanic separation between following units of the meter:
- supply
- voltage inputs
- current inputs
- RS485 interface
- Ethernet interface
- alarm outputs
- analog output
- temperature input Pt100
- binary inputs 0/5...24 V d.c.

3 BASIC REQUIREMENTS, OPERATIONAL SAFETY
In terms of operational safety the controller meets the requirements of the EN 61010-1 standard.
Remarks concerning safety:
The meter should be installed and connected only by a qualified personnel. All relevant
safety measures should be observed during installation.
Always check the connections before turning the meter on.
Prior to taking the meter housing off, always turn the supply off and disconnect the
measuring circuits.
Removal of the meter housing during the warranty period voids the warranty.
This meter conforms to all requirements of the electromagnetic compatibility in the
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 by the operator, and suitably marked.
4 INSTALLATION
The meter is intended to be fixed to the panel with mounting brackets as presented on Fig. 1.
The meter housing is made of a self-extinguishing plastics.
Fig. 2. Meter fitting

ND30IoT-09A 4 User's manual
Housing overall dimensions 96 x 96 x 77 mm, dimensions of the assembly hole 92.5 x 92.5 mm.
There are screw terminal strips on the outer side of the meter which enable the connection of
external wires of diameter up to 2.5 mm2.

5 METER DESCRIPTION
5.1 Current inputs
All current inputs are galvanically isolated (internal current transformers). The meter is adapted to
work with external measuring current transformers / 1 A or 5 A /. Displayed current values and
derivative values are automatically converted in relation to the introduced external current
transformer ratio.
5.2 Voltage inputs
All voltage inputs are galvanically isolated (internal transformers). Values on voltage inputs are
automatically converted according to the introduced ratio of the external voltage transformer.
Voltage inputs are specified in the order as 3x57.7/100 V, 3x230/400 V or 3x110/190 V,
3x400/690 V.

pressing the buttons (next page) or (previous page).
The page consists any 8 values selected from the Table 1 and displayed simultaneously on the
display. The page definition is described in the Display mode. Depending on the location, meter
buttons can perform different functions. Functions are described in the bar on the bottom of the
screen. If the button lacks description, it is inactive at the moment.

Information bar at the top of the screen displays the status of the alarm outputs, alarm conditions,
T1 and T2 temperature of the sensors connected to the first and second input of PT100, files
archive memory status, archive status, a symbol of Ethernet connection, the indicators of
receiving and transmitting data on the RS485 link, date and real-time clock. A symbol "phase
