9 DECOMMISSIONING
DANGER! Danger of death due to electric shock after decommissioning
Large parts of the battery storage system are still under full voltage even after decommissioning,
meaning there is a risk of a fatal electric shock if operators touch live parts.
CAUTION! Risk of injury due to electric shock after decommissioning
•
Discharging of the inverter’s capacitors can take several minutes even after switching off. For this
reason, please wait 15 minutes until the system has largely discharged.
•
The DC auxiliary circuit is not completely voltage-free after decommissioning; the voltage is merely
low (U
DC
≤ 60 V
DC
), meaning a fatal electric shock can no longer occur if operators touch live parts of
the DC auxiliary circuit.
ATTENTION! Possible damage to the unit due incorrect decommissioning
In the event of regular decommissioning, the output must be 0 kW before the APU HV1000-S is decommis-
sioned using the ON/OFF switch. Use the SMA LCS Tool to reduce the output to 0 kW.
The DC disconnecting switch on the underside of the SMA STPS 60 must remain in the “ON” posi-
tion, and under no circumstances must it be set to “OFF”.
1
Reduce the output of the SMA STPS 60 to 0 kW. Please refer to SMA’s product documentation or the
website www.sma.de for further information.
2
Press the “Plant Stop” button at the top right in the LCS tool. The Inverter Manager lowers the output
of the SMA STPS 60 to 0 kW, opens the AC contactor of the SMA STPS 60 and gives the command to
the APU HV1000-S to disconnect from the DC path. Wait until the audible opening of the contactors in
the SMA STPS 60 and the APU HV1000-S is heard. Please refer to SMA’s product documentation or the
website www.sma-uk.com for further information.
NOTE:
The SMA LCS Tool is an SMA product. For this reason, TESVOLT cannot guarantee the accuracy of
information provided about this and other products belonging to SMA. Binding information can only be
found in SMA’s valid product documentation for the relevant product.
3
The 125 A NH00 fuses
9.1
or
37
(see “5.8 Connector panel” on
page 19 et. seq.) for the battery inverter can now be removed
from the left fuse holder. Then close the fuse holder.
4
Switch off the battery by pressing the ON/OFF switch (“SWITCH”)
17
on the APU HV1000-S (the green LED must go out).
For systems with multiple TS HV 70 Outdoors, each
APU HV1000-S has to be switched off.
