1. Safety
1.1 Objective
This operating manual has been prepared for persons who install, connect, commission and operate the
EM-PQ 2300 Power Quality Analyzer.
1.1 Safety instructions
DANGER!
The following instructions must be observed to prevent danger to life and limb or damage to
equipment and other assets:
Installation and commissioning of the instrument in industrial plant must be carried out in
strict compliance with the standards IEC 61508 and DIN VDE 0801.
Any other laws, standards, regulations and safety rules (IEC, EN, VDE, etc.) relevant to
this product and the protection of persons and assets must be observed. In Germany, it is
essential to comply with the Equipment Safety Act (GSG) and the regulations of the
German Social Accident Insurance Institutions. In other countries, the equivalent local
regulations must be followed.
Installation, commissioning, modifications and retrofitting may only be carried out by
appropriately qualified personnel.
In Germany, it is essential to comply with the regulations of the Social Accident Insurance
Institution covering electrical installations. In other countries, the equivalent local
regulations must be followed.
The instrument contains live components at the AC supply voltage and must therefore not
be opened.
If the instrument is visibly damaged, it must not be installed, connected or commissioned.
If the instrument does not work after commissioning, it must again be isolated from the
power supply.
Do not expose the instrument to direct sunlight or high temperatures, as these could
damage it or shorten its service life.
Do not install the instrument near to sources of heat such as radiators or other devices
that generate or transmit heat.
Do not expose the instrument to rain, water, dampness or high levels of humidity. Avoid
direct contact with water at all cost.
Failure to observe the safety instructions can result in death, serious injury or severe
damage to equipment and other assets.
The safety of the system in which the EM-PQ 2300 is incorporated is the responsibility of
the persons installing and operating the system.
This operating manual may be changed without notification. Please consult our website
www.frako.com for the up-to-date version.
When work is carried out on the instrument terminals and connecting cables, there is a risk of live
components being touched inadvertently. The working voltage may present a hazard to health or
may even be life-threatening.
Observing the above safety precautions can significantly reduce the risk to life and limb.
The user must ensure that all operators are familiarized with this operating manual and follow it at all
times.
This operating manual must be read through carefully and completely before the instrument is installed,
connected, commissioned and operated. All actions taken must be in accordance with this operating
manual.

3. Instrument description
The EM-PQ 2300 Power Quality Analyzer is a useful addition to the FRAKO range of products. It offers the
possibility of carrying out long-term network analyses in compliance with EN 50160 or EN 61000-2-4, monitoring
short supply network sags and performing TN-S system measurements. Harmonics up to the 51st are measured.
The user can select from several options for recording data, e.g. for analysis of the power demand profile over
time.
An outstanding feature is the possibility to acquire measurement data from the neutral conductor N, and
even more importantly from the earth conductor PE, in addition to the three phases L1, L2 and L3. Voltage
and current can be measured in all conductors.
Measurement readings, graphs, alarms and waveforms can be viewed on the optional EM-FD 2500 Display
instrument, which can show data from up to seven EM-PQ 2300 or other suitable instruments of the FRAKO
Energy Management System. The devices whose data are to be displayed are selected using the keys on the
EM-FD 2500 to navigate a menu.
The EM-PQ 2300 Power Quality Analyzer has a DIN rail mounted casing with plug-in connectors for simple
installation and connection to suitable individual instruments of the FRAKO Energy Management System.
Installation can be further simplified with the optional DIN rail bus connector,
which can be obtained from the manufacturer, Phoenix Contact,with the order
code HBUS 161,6-16P-1S BK, Article No. 2278555. This enables the bus
connections of the EM-PQ 2300 Power Quality Analyzer or EM-MC 2200
Maximum Optimizer instruments mounted next to each other on the same DIN
rail to be automatically connected to each other. It is therefore no longer
necessary to wire these connections separately from instrument to instrument,
significantly reducing the costs of installation.
The instruments are connected to the:
- FRAKO Starkstrombus
- Display bus, including the Display instrument power supply
Figure 2: DIN rail bus connector
