ü
The battery modules must remain switched off at all times during in-
stallation. Therefore:
„
Before installation, ensure that the ‘Power’ and ‘Status’ lights are off.
„
Do not press the power button on the battery module.
CAUTION
Improper handling of battery modules
Emission of toxic substances!
„
Do not open battery modules.
„
Do not damage the battery modules.
• Switching the battery modules on/off manually by pressing the green Power
key is not necessary. When the battery modules are connected correctly, they
will be fully operated by the storage system controls and
do not need to be
switched on/off manually.
• The Power key is only intended for service purposes and only authorised ser-
vice technicians are permitted to use it.
Nevertheless, if a battery module has been switched on manually:
„
Press and hold the Power key on the battery module for 3 seconds until all
status lights on the battery module are off.
The voltage of the battery modules does not need to be measured before
installation. The modules connect to each other after the storage system is
commissioned and the voltages are automatically adjusted.
The ‘Power’ and ‘Status’ lights give you information about the current state of the
battery module:
