1 About this document
Range of validity
This user manual applies to the E230 ZxR100xC and ZMR100xR
polyphase residential electricity meters.
The meter conforms to standards:
IEC 62052-11
IEC 62053-21
IEC 62053-23
IEC 62053-31
EN 50470-1
EN 50470-3
Purpose

Restriction for meters with software version up to and including
v21.x.x (ZxR100xC) and v51.x.x (ZMR100xR):
The meters may not be used in networks with significant disturbances in
the frequency range of 2 kHz to 150 kHz since the intended operating
conditions of the meters according to the harmonised standards
EN50470-1 and EN50470-3 assume no significant noise currents and
voltages in this frequency range. Such significant disturbances occur, for
instance, in large photovoltaic systems (influence of the inverters with
high emissions of extreme harmonics) and can cause additional errors in
the meters, even though the meters meet all applicable standards and
directions.

Restriction for meters with software version up to and including
K75 (ZxR100xC) and K52 (ZMR100xR):
Follow the measurement times for meter constant and dial tests
specified in section 7.2.1. When switching a load (< 0.5 A to > 1A) on
and off at regular intervals of about 20 minutes, an additional error of
about 0.1% can occur. The deviation may be higher, if the load is
switched on and off more often. The meter meets all specifications and
applicable standards and regulations.
Contained in the user manual is all information required for the
application of the meter for the intended purpose. This includes:
Characteristics and functionality of the meter.
Information about possible dangers, their consequences and
measures to prevent them.
A detailed description of the tasks to be performed during the entire
life-cycle of the meter (configuration, installation, commissioning,
operation, maintenance and disposal).

Installation aids
Indication of the presence of phase voltages, rotating field
and direction of energy
Power indicator
Storage of additional information, such as operating times (readable
via optical interface or, if present, the CS or RS485 interface).
2.2 Intended use and installation
The E230 ZxR100xC and E230 ZMR100xR meters record active and
reactive energy consumption primarily in three-phase four-wire
networks. The meter can operate on one phase (any phase and neutral),
two phases (any two phases and neutral) and three phases with or
without neutral. In addition, E230 ZxR100xC can also operate on three-
phase delta configuration (F-Circuit). For this purpose, the meters are
directly installed in the supply line by the energy supply company and
are read regularly for energy charging purposes. They are used
according to the technical specifications stated in the respective data
sheets and in conjunction with this document.

2.5 Data readout
The Utility Company can take readings from the meter at any time in the
field. .MAP110 tool can be used for detailed local readings. There are
three possible ways to perform local readings, they are:
Take readings directly from the LCD display. The registers will either
scroll through a configurable loop or the Cycle Display button can be
pressed to move through the available registers.
With the aid of a suitable laptop computer or PDA, more detailed
readings can be taken using the optical port. This method of
communication is also utilised for the reconfiguration of certain
meter functions, for example, reset registers and change tariff
details. For the necessary hardware and software, please contact
the Landis+Gyr Metering Sales Team who will be happy to assist.

danger level, i.e. the severity and probability of any danger, in the
individual sections of this document.
Warning
Used to indicate a dangerous situation that could cause bodily injury or
death.
Caution
Used to indicate a situation/ action that could result in material damage
or loss of data.
Note
Used to indicate general guidelines and other useful information.
In addition to the danger level, safety information also describes the type
and source of the danger, its possible consequences and measures for
avoiding the danger.
3.2 Responsibilities
The owner of the meters – usually the utility company – is responsible
for assuring that all persons engaged in working with meters:
Have read and understood the relevant sections of the user manual.
Are appropriately qualified for the work to be performed.
Strictly observe the safety regulations (laid down in section 3.3) and
the operating instructions as specified in the individual sections.
In particular, the owner of the meters bears responsibility for the
protection of persons, prevention of material damage and the training of
personnel.
For this purpose, Landis+Gyr provides training on a variety of products
and solutions. Please contact your local Landis+Gyr representative if
interested.

3.3 Safety regulations
The following safety regulations must be observed at all times:
This equipment does not contain a disconnection device. Means for
disconnection from the electricity supply must be provided as part of
the building installation. Do not work on the equipment unless the
supply is disconnected. If disconnection is done by removal of fuses
or other cut-outs, the removed disconnection devices must be kept
secure from replacement while work is performed. If disconnection
is provided by a switch, the switch shall conform to the requirements
of IEC 947-1 and IEC 947-3 or equivalent.
This equipment does not contain an over-current protection device.
Over-current protection must be provided as part of the building
installation. Maximum over-current device rating is 125 A at 415 V,
conforming to the requirements of BS1361 or equivalent. The meter
connections must not be under voltage during installation or when
opening. Contact with live parts is dangerous to life. The relevant
main fuses should therefore be removed and kept in a safe place
until the work is completed, so that other persons cannot replace
them unnoticed.
Only suitably trained and qualified personnel shall be allowed to
work on the equipment. Local safety standards shall be observed
and shall take precedence over these regulations in points of
conflict.
The meter must be held securely during installation. They can cause
injuries if dropped.
Any meter that has fallen must not be installed, even if no damage is
apparent, but must be returned for testing to the service and repair
department responsible (or the manufacturer). Internal damage can
result in functional disorders or short-circuits.
The meter must on no account be cleaned with running water or
with high-pressure devices. Water penetration can cause short-
circuits.
The meter terminal cover should be secured in place before any
load is applied.
To avoid overheating, the meter must be connected using
appropriate cable sizes:
Currents up to 60 A: a cable with a minimum 16 mm2cross-
sectional area.
Currents up to 100 A: a cable with a minimum 25 mm2cross-
sectional area.
Currents up to 125 A: a cable with a minimum 35 mm2cross-
sectional area.
