Universal heavy current measurement unit A
Security instructions
Perfect and safe operation requires that these safety instructions as
well as the device handbook no. 157 679 from the supplied Doku-CD
have been read and understood.
The installation and commissioning should only be carried out by trained
personnel.
Check the following points before commissioning:
– that the connection wires are not damaged, and that they are not live during
wiring,
– that the power fl ow direction and the phase rotation are correct.
The instrument must be taken out of service if safe operation is no longer pos-
sible (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 modifi cations to the instrument.
The instrument is not equipped with an integrated circuit breaker. During instal-
lation check that a labeled switch is installed and that it can easily be reached
by the operators.
The device is maintenance free. Unauthorized repair or alteration of the unit
invalidates the warranty.
Application area
The A is a comprehensive instrument for the universal measurement, monito-
PLUS
ring and power quality analysis in power systems. The device can be adapted fast
and easily to the measurement task by means of the CB-Manager software. The
universal measurement system of the device may be used directly for any power
system, from single phase up to 4-wire unbalanced networks, without hardware
modifi cations.
Using additional, optional components the opportunities of the A
extended. You may choose from I/O extensions, communication interfaces or data
logger. The nameplate (fi g. 1) on the device gives further details about the present
version. The A may be equipped with or without display.
PLUS
Mounting
- Any mounting position is possible
- Devices with display are designed for panel mounting. The necessary panel cu-
tout and the required minimum distances are shown in fi gure 2. Slide the device
from outside into the cutout and fi x it by means of the two mounting clamps.
- Devices without display may be clipped onto a top-hat rail according EN50022
in a cabinet.
Electrical connections
A marked and easily accessible current limiting switch 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 availab-
le voltage and fault current.
Attention: Danger to life! Ensure that all leads are free of potential
when connecting them!
All voltage measurement inputs must originate at circuit breakers
or fuses rated 10 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 labelled circuit breaker or a
fused disconnect switch.
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.
PLUS
The assignment of the connections is as shown on the nameplate. See example
for an unbalanced 4-wire power system (Fig. 3).

Parameterization
A complete parameterization of all functions of the A
nication interface only using the CB-Manager software. For devices with display a
few parameters may also be set via the confi guration menu. The confi guration and
parameterization of the device is described in chapter 7 of the device handbook.
Please observe that the data on the type plate must be adhered to !
The national provisions (e.g. in Germany VDE 0100 "Conditions con-
cerning the erection of heavy current facilities with rated voltages
below 1000 V") have to be observed in the installation and material
selection of electric lines!
