3.1 multimess F144-PQ Summary description
The Power Quality Analyser and Fault Recorder multimess F144-PQ for low, medium and
high voltage networks is the central component of a system with which all measurement
tasks in electrical networks can be solved.
The multimess F144-PQ can be used as a Power Quality Interface according to power
quality standards such as IEC61000-2-2 / EN50160 or to check the technical con-nection
guidelines such as DIN VDE AR 4110 and DIN VDE 4120 and many more. Due to the availa-
ble SCADA interfaces such as Modbus RTU/TCP as well as IEC 61850, the device can also
be used as a highly accurate measurement transducer for all physically dened measured
variables in 3-phase systems parallel to the continuous recording of measured values
over a very long period.
In addition to the possibility of standard evaluations, the multimess F144-PQ also has a
high-speed disturbance recorder with a recording rate of 40.96 kHz/10.24 kHz and a 10ms
TRMS eective value recorder. This allows a detailed evaluation of grid disturbances.

3.3 Fitting
The multimess F144-PQ is used as a panel-mounted device and fulls IP54 in the installed
condition. Mounting must be carried out with the following cut-outs and mini-mum dis-
tances (see following gure). The maximum thickness of the panel for PQI-DE installation
is 8mm.
For mounting the multimess F144-PQ, four mounting brackets are included in the scope
of delivery. These must be snapped into the housing of the multimess F144-PQ at all four
corners (see picture below). The clamps must then be screwed against the panel with a
maximum torque of ve Nm using an Allen key (2.5 mm) on the back of the PQI-DE to
ensure that the PQI-DE is securely mounted in the panel cut-out.!

eyelet terminal for the connection and make sure it is tight!
DANGER! Danger to life due to electric shock!
Incorrect connection of this measuring instrument can lead to death,
serious injury or re hazard!
The functional earth must always be connected to PE potentia.

NOTICE! Material damage due to non-observance of the
connection conditions or impermissible overvoltage!
Failure to comply with the connection conditions or exceeding the permissible voltage
range may damage or destroy your device.
Before applying the supply voltage to the device, the following points must be
observed:
Voltage and frequency must correspond to the specications on the type label!
Observe the limit values as described in the technical data!
Observe features of the device
In the building installation, the supply voltage must be provided by a listed
miniature circuit breaker and fuse that meets the requirements of IEC 60947-1 and
IEC 60947-3!
The miniature circuit breaker must
- be easily accessible to the user and installed close to the device.
- Label for the respective device.
Do not take the supply voltage at the voltage transformers.

3.6 Mains connection for multimess F144-PQ
The mains connection of the multimess F144-PQ depends on the type of mains in which
the measurement is to be made.
The multimess F144-PQ is designed for direct measurement in low voltage (3 phase / 4
wire connection) for low voltage networks (TN, TT and IT networks) or for residential and
industrial applications. A special form of low voltage measurement is the measurement
4-wire / 1 phase connection with which three independent voltage circuits and current
circuits can be measured with the same ground conditions.
For medium and high voltage the device can be connected via suitable transformers.
A connection with three voltage and current transformers is possible as well as the con-
nection via transformer saving circuits (V-circuit, Aron circuit).
In addition, current measurements with small signal inputs are possible with the corres-
ponding sensor transformers
WARNING!
Personal injury and damage to property due to
nonobservance of the safety regulations
Before making any connections, please read this manual thoroughly and
follow the safety measures described here.
