You can now make the DC connections to the next battery mod-
ule. To do this, use two long “I” connectors
4.1
from the LV mod-
ule connector kit
4
. Two M8 x 20 hexagon flanged bolts
4.2
are provided in each connector kit for fastening.
.
The next DC con-
nector
4.1
is only fastened to the next battery module as part of
the process of connecting to the next battery module below. Ini-
tially, tighten the connections hand-tight only.

Continue using this procedure until you reach the last, lowest
module. The long “I” connectors
4.1
are initially fastened to the
last module hand-tight only using two M8 x 16 hexagon flanged
bolts
3.6
(part of the APU connector kit).
Cabinet extension only:
Two M8 x 20 hexagon flanged bolts
4.2
are also used to fasten the long “I” connectors
4.1
and the DC
cabinet connecting cables
18.1
/
18.2
on the bottom module. The
procedure is described in the next step.
DANGER! Incorrect installation of the DC cabinet connecting cables when extending a cabinet can
lead to a short circuit and life-threatening injuries.
If the DC connecting cables
18.1
/
18.2
are incorrectly installed, this may result in a short circuit. This
may cause components to become extremely hot or produce an electric arc which can lead to serious
injuries. Pay careful attention to the following points in order to avoid a short circuit:
•
Install the DC connecting cables
18.1
/
18.2
one after the other and always fasten the first DC con-
necting cable to both battery modules first before proceeding to fit the second DC connecting
cable.
•
Ensure the DC connecting cables’ contacts
18.1
/
18.2
do not accidentally touch other components
during the fitting procedure.
•
Ensure that wiring is carried out properly in accordance with section “5.9 Wiring the battery mod-
ules” on page 21 et seq.

Cabinet extension only:
Install all battery modules on the right
side from the bottom upwards. Attach two long LV I-shaped con-
nectors
4.1
between the modules using two M8 x 20 hexagon
flanged bolts
4.2
or M8 x 16
3.6
for the last module. Then
install each of the DC connecting cables
18.1
/
18.2
using two
M8 x 20 hexagon flanged bolts
18.4
. Connect the DC connecting
cable with red marking
18.1
to the positive pole and the blue
18.2
to the negative pole on the lowest module in the left and right
halves of the cabinet. Tighten all the connections hand-tight only.
16
Cabinet extension only:
Using the patch cable
18.3
, connect the
BAT-COM OUT connection on the lowest module on the left side to
the BAT-COM IN connection on the lowest module on the right
side. Connect the remaining BAT-COM connections on the rest of
the battery modules. Note the BAT-COM cabling specifications on
the left side of the cabinet in the subsequent installation steps.
