Purpose of Use
Restrictions for meters with software versions M51 to M52:
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 regulations.
Restrictions for meters with software versions M54:
Please follow the required test times for the meter constant or dial test,
mentioned in section 7.1.2. At switching on or off the load (between <0.5A
and >1A) regularly every 20 minutes, an additional error of about 0.1% can
occur. The deviation can be higher, if the load is switched more often. The
meter complies with all specifications. It fulfils all the valid standards and
regulations.
The ZCF100 meters record active and reactive energy consumption in all 1-
phase 2-wire networks. They are directly installed in the supply line by the
energy supply company and are read regularly for billing purposes.
The data is displayed on an LCD and is also available via optical interface
and with an AMR Module via CS, PLC modem, GSM/GPRS modem or
ethernet. When provided with transmission contacts, the meters can also
be used as transmission contact meters for telemetering. The rates can be
controlled externally with control inputs (on the AMR Module).
