7.2 Connecting the extension cabinet
The scope of delivery includes the battery cables, BMS communication lines
and battery screws for the highest extension level of the storage system. If the
maximum number of battery modules is not being installed:
„
Store the surplus components in the storage system (e.g. on the floor
plate). These will then be on hand if additional battery modules are in-
stalled later.
„
Ensure that the components are not damaged (e.g. when the cover is at-
tached and removed).
7.2.1 Positioning the battery modules
If just two battery modules are installed in the extension cabinet, they must al-
ways be mounted with the spacer plate on the middle battery shelf.

Position and secure the battery modules as de-
scribed for the storage system (see Positioning
the battery modules [P. 43]).
7.2.2 Connecting the BMS communication lines
• The first and last battery module are connected to the central unit of the storage system
using two BMS communication lines. These two lines are guided through the cable entry
plates on the storage system and on the extension cabinet.
• The battery modules are connected to each other via the BMS communication lines as
described in section Connecting the battery modules [P. 45].
