Introduction
1.3 Explanation of safety relevant symbols
These operating instructions contain notes that must be observed for your
personal safety and to avoid damage to equipment. These notes are identied
by a warning sign or information symbol, depending on the degree of hazard
they represent.
Warning
"Warning" means that death, major injuries or damage may occur if the appro-
priate safety measures are not taken.
Caution
"Caution" means that minor injuries or damage may occur if suitable safety
precautions are not taken.
Note
"Note" is an important piece of information on the product, its operation or the
respective part of the operating instructions to which special reference is being
made.
Disclaimer
The contents of these operating instructions have been carefully reviewed in
terms of the hardware and software described. Nonetheless, deviations cannot
be ruled out, and the manufacturer cannot guarantee 100% conformity. The
specications made in these operating instructions are reviewed on a regular
basis; any corrections required will be included in the next revision.

Introduction
1.4 Safety notes
In order to prevent operating errors, device operation is kept as simple as possi-
ble. This will enable you to start your device up quickly.
In your own interest, however, the following safety notes should be read care-
fully. The applicable DIN / VDE regulations must be observed for installation!
Power supply connection, setup and operation of the device must be per-
formed by qualied personnel only. Qualied personnel as dened in the
safety notes in this user manual are those authorized to set up, ground and
mark devices, systems and circuits in accordance with applicable standards and
regulations.
To prevent re and electric shocks, the device must not be exposed to rain or
humidity!
Before connecting the device to the power supply, check whether the local
power supply conditions comply with the specications on the device name-
plate.
Caution
A faulty connection may result in the destruction of the device!
For device connection, the data given in the connection chart must be com-
plied with (see “Connection chart”) and there must be no voltage in the con-
nection lines. When wiring, always ensure that all wiring material used is neither
damaged nor defective and that the polarity is correct!
In order to ensure proper and safe product operation, it must be transported,
stored, installed and assembled in accordance with the specications, as well as
carefully operated and maintained.
A visibly damaged device must generally be considered unt for use and dis-
connected from the power supply!
Error detection, repair and maintenance work may only be carried out in our
facilities or after contacting our service team. Opening the device unauthorized
shall render your warranty null and void. Correct operation can no longer be
guaranteed!
Opening the device may expose live parts. Capacitors in the device may still be
under load, even if the device has been disconnected from all voltage sources.
Open devices must not be operated!

Introduction
Systems that are at risk from lightning strikes must feature lightning protection
for all input and output lines.
1.5 Product liability
You have purchased a high-quality product. Only components of the highest
quality and maximum reliability are used.
Each device is subject to long-term testing before it is delivered.
For details on product liability, please refer to our general terms and conditions
for electronic equipment, which you can nd at www.kbr.de.
The warranty on device properties applies only if the device has been operated
in accordance with its intended use!
1.6 Disposal
Defective, outdated or disused devices must be properly disposed of.
If required, we are happy to dispose of the devices for you.

Device memory
2 Device memory
Non-volatile long-term memory
The device is equipped with an internal, non-volatile memory in which long-
term data is stored.
Buered real-time clock (RTC)
After an uninterrupted charging time (device connected to the supply voltage)
of approx. 8 hours, the buer capacitor will have a sucient charge to protect
the internal clock from failure due to lack of operating voltage for approx. 14
days.
Note
If the buer capacitor is discharged and there is no supply voltage, once the
device has been switched on the time settings will be incorrect and must there-
fore be reset.

Denition of terms
3 Denition of terms
Below, you will nd brief explanations of the terminology used in this manual.
Root-mean-square value:
By denition the square of the average value of a periodic or pulsating value is
referred to as the root-mean-square value. multimess D6 exclusively uses the
RMS values of pure periodic values.
Instantaneous root-mean-square value:
The value determined by the multimess D6 during its measurement intervals.
Measurement interval:
During a measurement interval, the electrical quantity “Voltage”or “Current”
of one phase is scanned. The resulting scanning spots are available for further
calculations. This interval is mainly determined by the A/D conversion.
Measuring cycle:
The measuring cycle is the time the measuring device needs in order to mea-
sure all the values recorded by the device for all three phases.
Firmware:
The operating system software implemented in the multimess D6’s microcon-
troller.
Load prole memory:
Saves the actual values of the measurment periods with timestamp.
Measurement period maximum value:
The measurement period containing the highest (maximum) value that oc-
curred.
Active/reactive power periods:
Actual active or reactive power within a measurement period.
Measurement period:
The period of time used to determine the average power demand. Typical inter-
vals: e.g. 15, 30, 60 minutes.
DIN rail
Top hat rail / mounting rail acc. to DIN EN 50022

Application/range of functions
4 Field of application/range of functions
multimess D6 is a compact, easy-to-use energy meter that records active as well
as reactive energy (for consumption and recovery).
This energy counting device was designed in accordance with the standards
DIN EN 61036 (IEC 1036), DIN EN 61268 (IEC 1268) and requirement specica-
tion 2.0 revision 12/97 by the German Electricity Association (VDEW).
Dual-tari counter function (HT/LT)
Consumption during high tari and low tari times is saved separately. Switch-
ing from high to low tari times and vice versa is either carried out by means of
a digital signal to be applied externally, e.g. from the energy supplier, or via an
internal clock. A display ashing on the front of the device indicates which tari
is active at the moment. When operated with the KBR Energy Bus, switching can
also be carried out centrally via the Multimaster or computer.
Convenient operation and display
The LCD serves to either display the measured values directly or enter the re-
spective parameters and conguration data. In addition, six LEDs serve to show
the status and monitor the functions. Four buttons facilitate clearly structured
navigation through the menus.
For 100 to 400 V networks
The multimess D6 can be applied in three-wire as well as four-wire networks.
If the measuring value displays in the three-wire network are incorrect, a ze-
ro-point creator should be used. The unit can be implemented in 100 V as well
as in 400 V networks for direct measurement. Using a transducer adaptor, up to
700 V can be connected to the meter. Higher voltages can only be connected
via external voltage transformers, whereby primary and secondary voltage can
be freely programmed. The measuring voltage inputs of the device measure
directly, i.e. they are not metallically separated by a voltage transformer!
For energy supply networks with outer conductor connected to the earth po-
tential, suitable control gear with electrical isolation (e.g. voltage transformer)
must be used.
x/5A or x/1A freely programmable
The measuring inputs for current must always be fed via current transformers,
while the transformer ratio is programmable. The primary current value as well
as the secondary current value can be selected.
Programmable pulse output
Active energy or reactive energy proportional pulses can be output via a
programmable output laid out as an S0interface. The pulse output type (in
proportion to active or reactive energy
