INSTALLATION
Network analyzer ANRET M-90A-BUS may only be used in three-phase systems 230V AC
Phase-neutral, with 400V AC Phase-Phase voltage between lines.
As for installation directions, follow the diagram on page 34:
− for 4-wire three-phase systems (3 phases + neutral) also with non-symmetrical
and/or non-balanced systems, connect the neutral lead to terminal 1
− for 3-wire three-phase symmetrical and balanced systems, it is possible not to
connect the neutral lead
For correct measurement, the 3 phase leads coming from the distribution panel must
be inserted in the through holes vertically from above; failure to do so will cause a
connection-error warning to appear on the display. In case of a connection error, the
display will indicate which phase or phases are misconnected (cfr. "ERROR MESSAGES
– MISCONNECTION" ).
