1 Prologue
This manual describes all designs of the DIZ meter (firmware version 3.03 and higher).
Please note that the meters can be designed differently regarding, for example,
configuration, interfaces in-/outputs etc. It is therefore possible that meter features are
described here which do not apply to the meter(s) used by you.
1.1 Safety tips
The meters are to be used exclusively for measuring electrical energy and must only be
operated within the specified technical data (see also nameplate).
When installing or changing the meter, the conductor to which the meter is connected
must be de-energised. Contact to parts under voltage is extremely dangerous. Therefore
the relevant back-up fuse is to be removed and stored so that other people cannot insert
this unnoticed.
Before opening the meter, the secondary circuit of the current transformer must definitely
be short circuited. The high voltage on the current transformer is extremely dangerous
and destroys the current transformer.
With incorrect meter installation the S0-inputs can lead to line voltage.
Attention: Danger!
The local standards, guidelines, regulations and instructions are to be obeyed.
Only authorized personnel are permitted to install the electricity meters.
With storage, transport and operation, the meter it is to be protected against dampness,
dirt and damage. During operation, pay attention that the meter is sufficiently cooled.
1.2 Maintenance and guarantee tips
The meter is maintenance-free. With damages (e.g. due to transportation, storing) no
repairs may be carried out independently.
As soon as the meter is opened, the guarantee claims cease. The same applies in case
the defect can be traced back to external influences (e.g. lightning, water, fire, extreme
temperatures and weather conditions, improper or negligent use or treatment).

2 Mounting and installation
2.1 Mounting the meter
Meters from the series DIZ are designed for mounting on DIN-rails TH 35-7.5 accord. to
DIN 60715.
Figure 1: Dimensions (direct connected meter)

2.2 Installation
When installing the meter, please pay careful attention to the connection diagram which
can be found on the inside the terminal cover. On page 8 you can find examples of
connection diagrams.
The direct connected version from the series DIZ can be connected to a 3- or 4-phase
busbar with a left-sided N-connection. The busbars are suitable e.g. for automatic
circuit-breakers from AEG, Hager, Siemens, Moeller, Hager and Geyer.
Meters for direct connection are to be protected against short circuits with a back-up fuse
of 63 A and for transformer connected meters of < 10 A in the voltage path. The control
input is to be protected with a back-up fuse of 0.5 A.
In order to protect the DIZ from unauthorized access, the meter can be equipped with a
seal at the sealing eye can be sealed (see page 12).
The current and voltage supply inputs, the control input and the pulse output can be
found on the top of the meter.
The current outputs, the optional electrical interface and, with direct connected meters,
the connection for the busbars can be found on the bottom of the meter.

Note:
Please ensure when installing the meter that, after threading the connecting leads,
the screws are tightened to the correct torque according to EN 60999 in order to
guarantee a safe contact. The torque depends on the type of the connecting leads
and the maximum current.
In order to avoid damage to the meter the valid, maximum torque for the terminal
clamps may not be exceeded.
2.2.1 Connection examples
In the following you can find examples of some connection diagrams. When connecting a
meter pay attention to the connection diagram which can be found on the inside of
the terminal cover or in the delivery documents.

3 General description
The DIZ meter is a digital 1- or 2- tariff meter for measuring positive- and negative active
energy in 2-, 3- and 4-wire networks. Tariff switching takes place via an external control
input.
DIZ meters are principally used for energy data registration in the industry and building
installation, switching stations and the field of energy supply.
The compact design of this meter allows “space saving” mounting (only 6 pitch wide) and
also connection via cable bridges or DIN-Rail.
The DIZ meter in the transformer connected version is equipped with a transformer ratio
which can be set for the registration of the real energy consumption. The transformer
ratio can be set directly at the meter via the operation button (only with uncertified
meters).
The energy consumption values are displayed with 8 digits on an LC-Display.
They can, however, also be given out via a secondary or primary pulse output and/or via
an electrical interface (M-Bus, LON or RS485). With the secondary pulse output the
pulse constants and pulse length can be set, with the primary pulse output they are fixed.
The DIZ is available in class accuracy 1 or 2 according to IEC 62053-21 resp. class
accuracy B or A according to EN 50470-1, -3.
