2. Safety notes
Device may only be disposed in a professional manner!
The installation and commissioning should only be carried out by trained personnel.
Check the following points before commissioning:
– that the maximum values for all the connections are not exceeded, see "Technical data"
section,
– that the connection wires are not damaged, and that they are not live during wiring,
– that the power flow direction and the phase rotation are correct.
The instrument must be taken out of service if safe operation is no longer possible (e.g. visible
damage). In this case, all the connections must be switched off. The instrument must be
returned to the factory or to an authorized service dealer.
It is forbidden to open the housing and to make modifications to the instrument. The instrument
is not equipped with an integrated circuit breaker. During installation check that a labeled switch
is installed and that it can easily be reached by the operators.
Unauthorized repair or alteration of the unit invalidates the warranty.
3. Device overview
3.1 Brief description
The LINAX PQ3000/PQ5000 is a comprehensive instrument for the universal measurement and
monitoring in power systems. A full parameterization of all functions of the device is possible directly at
the device or via web browser. The PQ3000 fulfills all requirements of a class A device in accordance with
the power quality standard IEC 61000-4-30 Ed.3.
Using additional, optional components the opportunities of the device may be extended. You may choose
from I/O extensions, communication interfaces and uninterruptible power supply. The nameplate on the
device gives further details about the present version.
3.2 Available measurement data
The device provides measurements in the following subcategories:
a) Instantaneous values: Present TRMS values and associated min/max values
b) Energy: Power mean-values with trend and history as well as energy meters. Mean-value
progressions (load profiles) and periodic meter readings are also available.
c) Harmonics: Total harmonic distortion THD/TDD, individual harmonics and their maximum values,
phase angle of the harmonics
d) Phasor diagram: Overview of all current and voltage phasors and phase sequence check
e) Waveform of current and voltage inputs
f) Events: State list of monitored alarms, chronological lists of PQ events and self-defined alarms /
events as well as operator events.
g) PQ statistic: Data of the statistical power quality analysis

4. Mechanical mounting
Please ensure that the operating temperature limits are not exceeded when determining the
place of mounting (place of measurement).
By installing, the device becomes part of an electrical power installation that must be
designed, operated and maintained in accordance with country-specific regulations so that
the installation is safe and provides prevention against fire and explosion as far as possible.
It is the task of this installation to ensure that dangerous connections of the device can not
be touched during operation and that the spread of flames, heat and smoke from the interior
is prevented. This may be done by providing an enclosure (e.g. case, cabinet) or using a
room accessible to qualified personal only and compliant with local fire safety standards.
4.1 LINAX PQ3000
►The PQ3000 is designed for panel mounting
Dimensional drawing PQ3000: See section 10
Panel cutout PQ3000
Mounting of the device
The device is suitable for panel widths up to 8mm.
a) Slide the device into the cutout from the outside.
Orientation as shown.
b) From the side slide in the mounting clamps into the
intended openings and pull them back about 2 mm
c) Tighten the fixation screws until the device is tightly
fixed with the panel

PM 1001608 000 09 Device handbook LINAX PQ3000-PQ5000 8/102
Demounting of the device
The demounting of the device may be performed only if all connected wires are out of service. Remove all
plug-in terminals and all connections of the current and voltage inputs. Pay attention to the fact, that
current transformers must be shortened before removing the current connections to the device. Then
demount the device in the opposite order of mounting.
4.2 LINAX PQ5000
The device can be clipped onto a top-hat rail according to EN 60715. Orientation as shown.
Dimensional drawing PQ5000: See section 10
The device can also be mounted that the front of the
device protrudes through a cut-out in the enclosure. So
the operating buttons and the display become accessible.
With centric mounting using the below maximum cut-out a
gap between enclosure and device results, which does
not exceed 2.5mm on each side.

5. Electrical connections
Ensure under all circumstances that the leads are free of potential
when connecting them!
5.1 General safety notes
Please observe that the data on the type plate must be adhered to!
The national provisions have to be observed in the installation and material selection of electric lines,
e.g. in Germany VDE 0100 “Erection of power installations with nominal voltages up to 1000 V“!

You may have to remove first the plug-in
terminals to get access to the screw
terminals of the current inputs.
5.4 Inputs
All voltage measurement inputs must originate at circuit breakers or fuses rated 5 Amps or
less. This does not apply to the neutral connector. You have to provide a method for
manually removing power from the device, such as a clearly labeled circuit breaker or a
fused disconnect switch in accordance with IEC 60947-2 or IEC 60947-3.
When using voltage transformers you have to ensure that their secondary connections
never will be short-circuited.
No fuse may be connected upstream of the current measurement inputs!
When using current transformers their secondary connectors must be short-circuited
during installation and before removing the device. Never open the secondary circuit under
load.
The connection of the inputs depends on the configured system (connection type).

5.5 Power supply
A marked and easily accessible current limiting switch in accordance with IEC 60947-2 has
to be arranged in the vicinity of the device for turning off the power supply. Fusing should be
10 Amps or less and must be rated for the available voltage and fault current.
5.6 Relays
When the device is switched off the relay contacts are de-energized, but dangerous
voltages may be present.
Relays are available for device versions with corresponding I/O extensions only.

5.7 Digital inputs
The device provides a standard passive digital input. In addition, depending on the device version, there
may be 4-channel passive or active digital input modules available.
Usage of the standard digital input
►Status input
►Meter tariff switching
Usage of the inputs of the optional input modules
►Counting input for pulses of meters for any kind of energy (pulse width 70…250ms)
►Operating feedback of loads for operating time counters
►Trigger and release signal for monitoring functions
Passive inputs (external power supply with 12 / 24 VDC required)
The power supply shall not exceed 30V DC!

5.8 Digital outputs
The device has two standard digital outputs for which an external 12 / 24 VDC power supply is required.
The power supply shall not exceed 30V DC!
Usage as digital output
►Alarm output
►State reporting
►Pulse output to an external counter (acc. EN62053-31)
►Remote controlled output
PQ3000 PQ5000
1) Recommended if input impedance of counter > 100 kΩ
Driving a counter mechanism
The width of the energy pulses can be selected within a range of 30 up to 250ms, but have to be adapted
to the external counter mechanism.
