D000044352 en g – E230 Residential Electricity Meter – ZxR100xC/ZMR100xR – User Manual
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
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).
