8.2 Switching the storage system off to electrically
isolate it
High voltages inside the storage system
Danger to life due to electrocution!
►
Switch off the storage system.
►
Secure against anyone switching on the device again.
►
Wait five minutes so the capacitors can discharge.
►
Check that the device is disconnected from the power supply.
►
Only licensed electricians are permitted to carry out electrical work.
When working on the storage system it must be completely switched off to be
electrically isolated.
1.
Switch off fuse switch F1 and PV disconnector SPV, as described in section 8.1
(p.61).
2.
Switch off the grid voltage using the AC miniature circuit breaker.
3.
Take steps to ensure that these switches cannot be switched on again.
Figure 56: Removing the PV plug-in connectors
4.
Pull all of the PV plug-in connectors
out of the storage system. When
doing this, observe the
specifications of the connector’s
manufacturer.
5.
Wait at least 5 minutes until the
capacitors in the inverter have fully
discharged.
6.
Carefully check that there is no voltage inside the storage system.
The battery modules are the sole remaining sources of voltage in the storage
system.
