Extreme danger from electric shock!
Touching live parts can result in death.
All electrical work must be conducted by
a qualified electrician while observing
the VDE regulations, national and other
regulations!
Observe the pin assignment of the AC
bayonet connector. An incorrect assign
-
ment can result in the unit being de
-
stroyed.
No consumers may be connected to the
supply line from the solar inverter to the
mains fuse.
Always separate the solar generator
side first by quickly opening the DC load
break switch and then the grid connec
-
tion by switching off the corresponding
mains fuse.
If the voltage on the AC connection ex
-
ceeds the permissible value due to a long
line length or an insufficient cable cross-
section, the solar inverter will discon
-
nected from the grid. In power grids with
a low output and a high solar generator
output, this can lead to individual solar
inverters being switched off and then on
again several times.
Survey
The grid connection of the solar inverter
is made via an AC bayonet connector on
the underside of the unit. With a 3-phase
feed point (3-phase AC connection), a 5-
wire connection (L1, L2, L3, N, PE) is used
due to the 3-phase passive grid monitor
-
ing, while only a 3-wire connection (L1,
N, PE) is used on the single-phase feed
point. Feeding is always single-phase via
AC terminal 2.
