nality" on page 146)
• P02=mode with DIG1 input open (see "3.9.9 Phv menu - EVU functio-
nality - Photovoltaic functionality" on page 146)
• G01=0 (see "3.9.10 SG Menu - Smart Grid functionality (see also "8.8.1

Remote connection mode
For connection to the digital inputs, the equipment is equipped
with an additional 6-conductor cable (DIG1=EVU/SG0= white/
brown cable, DIG2=PV/SG1= green/yellow cable, DIG3= grey/
pink cable) already connected to the main -board (located inside
the device).
Remote connections to possible energy systems are the re-
sponsibility of the qualified installer (connection boxes, terminals
and connection cables).
The figures below give an example of a remote connection (fig.
67 and fig. 68), which must not be longer than 3 m.
