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 in-
side the device).
Remote connections to possible energy systems are the re-
sponsibility of the qualified installer (connection boxes, termi-
nals and connection cables).
The figures below give an example of a remote connection (fig.
61 and fig. 62), which must not be longer than 3 m.
