Before carrying out any operation, check that any external AC switch downstream to the
inverter (grid side) are in OFF position applying LOTO procedure on it.
Routing of the AC cables inside the inverter must be carried out from the
right side of the inverter.
Depending of the version of the AC panel installed on the inverter it will
be necessary to route the AC output and ground cables into different
ways:
-
Single-core configuration
11
(default):
In this configuration the AC output and earth cables must be inserted
into the proper cable glands, trying to follow a logical order based on
the position of the internal connections:
R = Phase R (indicated with a label near the AC connection busbar
21
)
S = Phase S (indicated with a label near the AC connection busbar
21
)
T = Phase T (indicated with a label near the AC connection busbar
21
)
N = Neutral (indicated with a label near the AC connection busbar
21
)
The earth connection can be made using the Protective earth point (int.)
25
or Protective earth point (ext.)
10
or both (this is required by regulations
in force in certain countries of installation).
= Earth (indicated with the protective earth symbol near the
protection earth connection point (int.)
25
or protection earth connection
point (ext.)
10
).
-
Multi-core configuration
56
(optional):
one M63 cable gland for the “R”, “S”, “T” phases and for the “N”
neutral cable and a M25 cable gland for the grounding cable.
This version of the AC panel
56
could be can be ordered separately.
Refer to “Kit of recommended spare parts” chapter for further
information.
Follow the procedure below to route all the requested cables:
