6.8.2 Connecting the battery modules
DANGER
High battery voltage (> 200 V)
Danger to life due to electrocution!
When battery cables are connected, the central unit always carries the voltage
of the battery modules, even if the storage system and mains voltage are
switched off.
To disconnect the battery voltage from the central unit:
„
Unplug the battery cables from all battery modules.
WARNING
Damage to battery cables due to improper routing
Danger to life due to electrocution!
„
Direct the battery cables through the openings in the battery shelves and
secure with cable clips.
„
Route the battery cables so that they are not kinked or crushed when the
cover is mounted or removed.
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).
• The battery modules are connected to the central unit of the storage system.
• The battery cables run from the individual battery module to the corresponding socket
on the central unit of the storage system. As a result, two battery modules each are con-
nected series. The battery module pairs are connected in parallel on the central unit.
