12 Decommissioning the battery modules
To decommission the battery modules completely upon completion of their service life, disassemble the battery modules
as described in the following.
Requirements:
☐ All circuit breakers of the battery modules are switched off.
☐ Original packaging or packaging suitable for the weight and dimensions of the battery modules is available.
☐ Mounting material for attaching the packaging on the Euro pallets is available (e.g., tie-down straps).
Procedure
1. Disconnect the battery modules from voltage sources (see Section9, page49).
2. Disconnect all DC and grounding cables.
3. Disconnect all communication cables.
4. If a fixing bracket is attached to the top battery module, detach and remove the fixing bracket (Torx M5).
5. Loosen the 2 screws (TX20) on the left and right on the top battery module that secure the battery module to the
component below it. On the last battery module, if it is wall-mounted, 1 locking screw (TX20) is located below the
battery module.
6. Pull the top battery module upwards.
7. If the battery module is to be stored or shipped, place it in packaging. Use the original packaging or packaging
that is suitable for the weight and dimensions of the battery module and that complies with the regulations for the
transport of batteries.
8. Disassemble the rest of the batteries, working from the top to the bottom. Proceed as described for the first battery
module.
9. If modules are wall-mounted: detach all wall mounting brackets and connecting elements from top to bottom and
remove.
10. Preparing battery modules for transport.
