Safety Instructions
The installation, installation and uninstallation of the meter may only be carried out by a certified electrician. For
your own safety and to avoid damage to the device, please observe the following safety information. The information
in the manual is important for your own safety in order to avoid damage. Please also comply with the generally
applicable local safety regulations for electrical installations
Danger!
Improper handling of live parts can lead to life-threatening injuries and accidents.
Before starting the installation, the power must be switched off for the main circuit
breaker. Incorrect labeling of fuses or circuit breakers can lead to the inadvertent
shutdown of the wrong system. This would mean that the system being worked on
would continue to be live. A suitable measuring device is used to check that there
is no voltage.
Guarantee Notice
Damage to the meter may only be repaired by the manufacturer. The meter may not be repaired
yourself if it is damaged. Claims under the guarantee can only be asserted if the prerequisite is that the
meter is not opened and / or the seal is undamaged. All guarantee and warranty rights expire when the
device is opened. The same applies to damage caused by external influences
The meter is maintenance-free.
Disclaimer
This description was created to the best of our knowledge and belief. The data in this manual are
checked regularly and necessary corrections are included in the subsequent revisions.

2 Preface
LoRaWAN mME DTZ541, it is a new innovative product that was developed for the German market.
The meter has 2 communication channels "LoRaWAN" and "LoRa". With the LoRaWAN network,
the meter can regularly send the defined measurement data to the server. In addition, the user can use
a LoRa adapter to query all measurement data from the meter at any time and also set all parameters.
As the "modern measuring device", the meter meets all legal requirements as well as standards and
normative documents. The main ones are listed in the following table:

4.1 Test-LED
The test LED of the DTZ541 illuminates the infrared light. It is used to output energy-proportional
active energy pulses and to display start-up and idling. When idling, the test LED lights up
continuously. If the meter measures above its start-up threshold, the energy-proportional pulses are
displayed. The accuracy of the DTZ541 is determined by the LED pulse outputs.
4.2 Notes on measurement accuracy
Only the specified meter types with the associated software version numbers are permitted for use of
the LMN interface in accordance with calibration law. For this purpose, the respective approved
software versions must be observed. The measured value data have a resolution of 4 decimal places.
All parties involved must ensure that the requirements from PTB-A 50.8, Appendix A3 for latency
times and applicable tariff application cases are complied with, also taking into account several
communication adapters connected to a smart meter gateway.

5.1 Attachment and connection
Before installing and commissioning the meter, check whether the meter is damaged. please check whether the
meter is damaged. If you detect any damage to the housing or a missing legal metrological fuse, the meter must not
be used if the seals are missing or the housing is damaged. The DTZ541 three-phase energy meter is suitable for
mounting on a meter position in accordance with DIN VDE 0603-2-1, three-point attachment DIN 43857-2 and
should be connected according to the circuit diagram.
Dimension
Double rates(DIN 43856 Schltg.: 4101MME) Single rates(DIN 43856 Schltg.: 4000MME)
5.2 Rates control
The rates control is carried out regulated by potential-free rates control terminals 13 and 15. With the
double rates meter, the rates can be switched by activating the terminals with system voltage by a
rates control device. Without control,rates 2 is active. rate T1 is activated when voltage is applied to
terminal 13.

5.3 Terminal block
In order to ensure asecure electrical connection between connecting cables and terminals, the clamping
screws must be tightened with a corresponding torque in accordance with DIN EN 60999-1. Tighten
the terminal screws with a corresponding torque in accordance with DIN EN 60999-1 to ensure a safe
electrical connection between the connecting cables and to ensure the terminals. The meter has tinned
copper shunts and can be contacted directly on copper or aluminum lines. The suitability of the meter
for connection is indicated on the meter.

6.2 Display of operation
The display test for 15 seconds when the voltage is restored. Upper display line segments and lower display line
segments alternately fade in and out 3 times.
The software version number of the metrological part is shown on the display with the associated checksum. The
software version is indicated with index 1.
If a communication adapter "BAB-01" is connected, the display then shows its software version number and the
associated checksum. The software version is indicated with index 2.
Rolling display of billing-relevant values. The display of the instantaneous power in the second line must be
enabled by entering a PIN:

User Manual LoRaWAN mME DTZ541 Three-phase electricity meter

Variant of single tariff for current direction + A: only register 1.8.0
Double tariff variant for current direction + A: alternating display between registers 1.8.1 and 1.8.2
Variant of individual tariff for current direction -A: only register 2.8.0
Double tariff variant for current direction -A: alternating display between registers 2.8.1 and 2.8.2
The 6 register values 1.8.0, 1.8.1, 1.8.2, 2.8.0, 2.8.1 and 2.8.2 are relevant for billing. They are always shown in the
same way as the variant in the first line of the display and only kWh without decimal places.
After entering the PIN, all the values shown in the second line are for customer information only and may not be
used for billing-related purposes. This applies in particular to the instantaneous power, the historical consumption
values (1d, 7d, 30d, 365d), as well as consumption values since zero setting.
If an error is detected which means that the measured values can no longer be used for accounting, the display shows
this message for 2 seconds after each partial step of the information to be displayed on a rolling basis.

7 PIN
7.1 INFO PIN
An optical data interface on the front is available forthe enduser. Its constant data rate is 9600 baud andthe character
encoding is 8-N-1. The transmission protocol is according to SML specification version 1.04. The interfaces work in
"PUSH" mode and send out one data record every second. The data has 3 variants. If you do not enter a PIN for the
"INFO OFF" setting, it is the "Reduced data record", otherwise it is the "Complete data record". The “manufacturer-
specific data record” can also be activated or deactivated via the rear interface.

7.3 LMN PIN
The MSB interface can be expanded as the LMN interface with the Holley communication adapter
BAB-01. Its constant data rate is 1Mbit and the character encoding is 8-N-1. The LMN interface meets
the requirements of the FNN specification sheet for basic meters, the PTB requirements for
communication adapters PTB-A50.8 and the requirements of BSI TR03109. This LMN interface can
communicate directly with SMGw.
