negative terminal of the feed-through terminal block of
the topmost energy storage module and screw it tight
(tighteningtorqueof4–4.5 Nm).
(2) Insert the RJ45 ribbon cable into the upper RJ45 connec-
tion socket on the upper energy storage module.

marked with the word ‘CoN2’.
Note that the cables to the inverter must be at-
tached to the wall in order to relieve the strain
on it!
(1) Connect the individual units as described in the section
‘Connecting the module to the inverter’. [4.3 Connecting
the module to the inverter; S.17]
(2)NextconnecttheHVcable(25 mm²)in parallel (not in
series) in a distribution box.
(3)UseanHVcable(50 mm²)toconnectthedistributionbox
with the inverter.
(4) Insert the RJ45 cable into the upper RJ45 connection
socket on the second unit’s upper energy storage module.
(5) Insert the other end of the same cable into the lower
RJ45 connection socket on the first unit’s lower energy
storage module. The first unit does not have a terminating
resistor.
