y1 Instructions for use
yAccessory (optional):
• Path separator
If the contents are incomplete or damaged, please contact your supplier.
Store, use and transport the device in such a way that it is protected
against moisture, dirt and damage.
Important information
These instructions for use are part of the documentation.
These instructions list all the dierent device versions. Some of the fea-
tures described herein may not be applicable to your particular device.
Please see the product manual for more comprehensive
information about the device. Please also observe all the docu-
ments included with other components.
Target audience
These instructions are intended for technicians who are responsible for
the installation, connection and servicing of the devices.
The device must be installed and put into operation only by qualied
electricians in accordance with generally accepted rules of technology
and the regulations, which are relevant for the installation of telecom-
munications equipment and end devices.
Intended use
The meter is intended to be used solely for the measurement of electri-
cal energy, and it must not be operated outside the specied technical
data (see name plate).

Maintenance and warranty instructions
The device requires zero maintenance. It is not permitted to make any
repairs in the event of any damage (e.g. due to transport or storage).
If the device is opened, the warranty and the Declaration of Conformity
will be rendered null and void. The same applies where a defect is
caused by external factors (e.g. lightning, water, re, extreme tem-
peratures and weather conditions), or by improper or careless use or
handling.
The seals may only be broken by authorised personnel.
Care and disposal information
DANGER
Risk of fatal injury in case of contact with live parts!
Before the housing of the meter is cleaned, all conductors that
the meter is connected to must be de-energised.
Use a dry cloth to clean the device housing. Do not use any chemical
cleaning agents!
The following table names the components and how they are to be
treated at the end of their life cycle.
Components Waste collection and disposal
Printed circuit
boards
Electronic waste: Dispose of such waste in accord-
ance with the local regulations.
LEDs,
LC display
Hazardous waste: Dispose of such waste in
accordance with the local regulations.
Metal parts Recyclable material: Sort such material and send it
for recycling.
Plastic parts Send sorted plastic parts to a recycling plant
(regranulation) or, where applicable, to a waste
incineration plant (thermal energy generation).

Components Waste collection and disposal
Battery Take safety precautions against short circuits before
disposing of the batteries. Dispose of the batteries
in their original packaging or insulate the terminals.
Do not dispose of batteries with the domestic waste.
Instead, observe the locally applicable waste and
environmental protection standards.
Basic safety instructions
yRead all the enclosed instructions and information.
yObserve the warnings on the device and in the documents.
yAlways be aware of safety issues and hazards when working on the
device.
yThe customary local occupational health and safety regulations for
electrical installations must be observed during assembly, installation
and removal of the device.
yMake sure that the installation and operating location of the device
meets the specications in the technical data.
yBefore assembly, check the devices for any transport damage and
other externally visible damage.
yOnly use the device if it is in a technically awless state, and solely
in line with its intended use.
yThe connection cables used to connect a meter must be selected
for type, cross section, voltage and temperature. In the process,
the maximum load on the meter and the installation environment
must be considered.
yAttach ferrules to exible wires.
yObserve the maintenance and warranty instructions.
yIf the mains power fails and then returns, there is no need to do
anything to the meter.

General description
This generation G DIZ is a digital single-rate, two-rate or four-rate tari
meter for measuring positive and negative eective and reactive energy
in 2, 3 and 4-wire networks. Tari switching is performed via the internal
real time clock (RTC) or an external control input.
The device is primarily designed for use in energy data collection for
industrial engineering and building technology, and for use in the utility
sector.
In the transformer version, the meter has an adjustable transformer ratio
for recording the actual energy consumption. The transformer ratio can
be adjusted directly on the meter with the control button.
If the meter is to be used for billing purposes, the editing menu must
be locked irrevocably. The transformer factors can then no longer be
modied.
Furthermore, the energy consumption values can be output via second-
ary or primary pulse outputs and/or via an electrical two-wire (M-Bus) or
RS485 (M-Bus, SML, Modbus-RTU®) interface.
The pulse constant and pulse length can be adjusted, depending on the
version of the meter.
The meter can be operated as a secondary meter (energy measured on
the secondary side of the transformers) or, by setting the transformer
factors, as the primary meter (actual energy on the primary side of the
transformers).
