AT 7580-EM111M and -EM24M are compact electric meters that are easy to install. AT7580-EM... fits in every application, wether it is for industry or an apartment, where measurement of electricity consumption should be made. AT7580EM has accuracy +/- 0,5% RDG (current/voltage).
In the front there is a digital display that shows kWh and kW and a LED. The LED blinks with a frequency of 1000 impulses/kWh (least period of 90ms and maximum frequency 11 Hz). KWh consumption is measured acc. to EN6253-21 (class 2).
The joystick (not EM10) in the front also shows you actual current per phase (A) and direction as well as reactive consumption (kvarh) and effect (kvar). The meter indicates the wrong phase sequence by lighting a symbol on the display. The installation is simple since the currentdirection does not matter and that neither external power supply nor any external power transformation is required.
AT7580-EM111M and AT7580-EM24M has an integrated M-bus interface acc. to EN 13757-1. Possible budrates are 300, 2400 and 9600.

The M-bus-connection is polarity-independent.
A standard shielded (4 x 0.8 mm diameter / 0.5 mm2 phone type) or standard power cable type (1.5 mm2) can be used.
Every individual M-Bus slave must be assigned an unique primary- or secondary adress depending on the addressing method. Primary adress: 1 to 247, specified in meter "Address". Secondary address: specified by serial number (Sn:) on both label and display.
Measure the voltage across the M-Bus slave connection to confirm M-Bus master connection. The voltage should be between 24-48 VDC.
SAFETY
Read through the manual carefully. If the instrument is used in a - by the manufacturer - unspecified way, the safety of the instrument may be reduced.
Maintenance: make sure that all the connections are properly connected to avoid malfunction or damage to the instrument.
To keep the instrument clean, use a slightly damp cloth; do not use any abrasives or solvents. We recommend for the instrument to be disconnected before cleaning.
