1 APPLICATION
NR30BAC 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 20 x 4 LCD character display. The meter enables controlling
and optimizing the operation of power electronics devices, systems and industrial installations.
It provides measurement of: RMS voltage and current, active, reactive and apparent power, active,
reactive and apparent energy, power factors, 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 voltage and
current ratios of measuring transformers / for indirect connections /. Indications of power and energy
take into consideration values of programmed ratios. The values of the measured quantities can be
transmitted to the host system through RS485 interface or Ethernet interface, relay outputs signal
overruns of the selected parameters.
The meter has a galvanic separation between the individual blocks of:
- power supply,
- voltage inputs,
- current inputs (for versions In 1 A/ 5A),
- RS485 Interface,
- Ethernet/ BACnet IP Interface:
- alarm outputs,
2 METER SET
Complete set of the Analyzer includes:
1. NR30BAC meter 1 pc.
2. User’s manual 1 pc.
3 BASIC REQUIREMENTS, OPERATIONAL SAFETY
In terms of operational safety, the meter meets the requirements of DIN EN 61010-1.
Safety instructions:
The meter installation and connection should be made by qualified personnel. All available
protection requirements must be taken into consideration.
Before turning the meter on 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 suitably marked.

NR30BAC-09AUser's manual 3
4 INSTALLATION
The meter is adapted for installation in a modular installation switchgears on a 35 mm support rail.
The housing of the meter is made of plastic.
Housing dimensions are 105 x 110 x 60 mm. Outside the meter there are screw terminal strips that allow
connection of external wires with a cross-section up to 5.3 mm2 / indirect measurements/ and up to 16
mm² /direct measurements.
Fig.1. Overall dimensions of NR30BAC meter
5 DESCRIPTION
5.1 Current inputs
All current inputs are galvanically isolated (internal current transformers). The meter is adapted for direct
connections / up to 63 A/ or for use with external current transformers / 1 A or 5 A /. Displayed values of
currents and derivative quantities are automatically converted according to the introduced external
current transformer ratio.
5.2 Voltage inputs
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 up to 3x100/170 V
or 3x230/400 V up to 3x400/690 V.

6 COOPERATION WITH S4AO
For NR30BAC versions with the S4AO block of 4 analog outputs, side connector for connecting
blocks is included. The connector can also be ordered separately: order code 24-171-01-00016
Fig.7. Connecting blocks using the side connector
Fig.8. Connection of NR30BAC with S4AO using RS485 interface
The S4AO module communicates with the NR30BAC meter via the RS485 Modbus Master interface,
therefore cooperation with S4AO excludes the use the NR30BAC meter RS485 interface for
communication with another Master.

8.1 Measurement mode
In the Measurement mode, the values of quantities are displayed acc. to the pre-programmed or user-
configured pages in the Displaying mode.
The change of the page is done by pressing (next page) or button (previous page).
Pressing the button displays the minimum, maximum or current value (no symbol) of the
displayed quantity. Resetting minimum values is done by brief pressing the button, and then
; resetting maximum values by pressing respectively and .
When displaying inductive or capacitive reactive power or energy, a marker is displayed that indicates
the nature of the load ”L” at inductive load or “C” at capacitive load.
When displaying active energy, the "+" sign displays active energy import or "-" active energy export.
Exceeding the upper or lower indication range is indicated on the display by  or . When
measuring averaged values (P DMD, S DMD, I DMD ) single measurements are done with a 0.25
second quantum. Averaging time can be chosen: 15, 30 or 60 minutes. Until the time all averaged
samples are obtained, the values are calculated from already measured samples.
The current in the neutral wire IN is calculated from phase current vectors.

This mode is used to set the meter parameters. To enter the Parameters mode, press the button
for approx. 3 seconds, and then press the or select the Parameters mode and accept
with the button . Access to configuration of parameters is protected by password, if it has been
introduced and is different from zero. When the password is 0000, the password prompt is bypassed. If
the password is incorrect, the message "Incorrect password" is displayed. Read-only menu.” is
displayed. Then you can view the parameters, but the changes are blocked.
When the password is valid or not entered, we can set values according to Table 1.
Using we select a parameter and confirm using the button .Then using we
select the parameter feature or the desired parameter values are set. The active position is indicated by
the cursor .The selected characteristic or value of the parameter should be confirmed by
pressing the button or canceled by simultaneous pressing . To exit the Parameter
procedure, press the button or wait for about 120 seconds. Exit the Parameters selection

During a parameter change, it is checked whether the value is within the range. In the case of setting the value
out of range, the value is set to the maximum value (when the value is too high) or to the minimum value (when the
value is too low).
When changing the parameter "Voltage L - N", the parameter "Voltage L - L" is automatically converted ( x √3 ),

Other types of conditions:
H_on –always met;
HoFF –always not met,
3non –when the value of the measured quantity exceeds the "Upper value of condition” at any
phase - the condition will be met. The condition is disabled when the value of the measured
value at all phases is less than the "Lower value of the condition."
3noF –when the value of the measured quantity is lower than the "Lower value of condition” at
any phase - the condition will be met. The condition is disabled when the value of the measured
value at all phases is higher than the "Upper value of the condition."
3_on –when the value of the measured quantity at any phase will be between the "Lower value
of condition," and "Upper value of condition" - the condition is met. The condition will be disabled
if the value of the measured quantity is below the "Lower value of condition" or above the
"Upper value of the condition” at all phases.
3_oF –when the value of the measured quantity will be below the "Lower value of condition" or
above the "Upper value of condition” at any phase - the condition is met. The condition will be
disabled if the value of the measured quantity is between the "Lower value of condition" and the
"Upper value of the condition” at all phases.
In the 3rd series of alarms the alarm value must come from the following ranges: 01-09, 10-18
and 19-27 (acc. to table 7). They work with the same Hysteresis thresholds of the "Lower values
of condition" and "Upper value of condition" for each phase. The blanking of alarm signaling
occurs after simultaneous pressing of the buttons .
