. Use the
rack balancing bridge
3.3
from the APU connector kit on the first
module below the APU. The remaining rack balancing bridges
4.4
can be found in the module connector kit.
WARNING!
Possible damage to the unit due to incorrect BAT-COM wiring.
Incorrect connection of the BAT-COM communication cable leads to malfunctions in battery operation.
Ensure that wiring is carried out properly in accordance with section “5.9 Wiring the battery modules”,
page 21 et seq.

Wire the BAT-COM communication cable using the supplied patch
cables
3.4
and
4.3
. Using the patch cable
3.4
, connect the
BAT-COM
10
connections on the APU LV to the BAT-COM “IN” con-
nection on the battery module located beneath the APU LV. You
can then use a patch cable
4.3
to connect the same module’s
BAT-COM “OUT” connection to the next module’s BAT-COM “IN”
connection. Connect the remaining battery modules in the same
way using the patch cables
4.3
. The last battery module’s
BAT-COM “OUT” connection remains unused.

Finally, fit the side covers on the battery modules. Ensure the
brackets snap into place correctly.

Now lay the DC cables
5.1
/
5.2
starting from the APU LV to the
SMA Sunny Island or the Bat fuse
15
or
16
. Note that the cable
can only be shortened on the SMA Sunny Island or Bat fuse side.
To relieve the strain on the DC cables, install the two cable reten-
tion clips
