9 Shutdown
DANGER! Risk of death due to electric shock after shutdown.
Large parts of the battery system remain under full voltage even after shutdown. There is therefore a risk of a
fatal electric shock if the live parts of the storage system are touched.
DANGER! Risk of injury due to electric shock after shutdown.
• It can take several minutes for the inverter’s capacitors to discharge, even after the system has been switched
off. There is a continued risk of an electric shock until they are discharged. you should therefore wait 15 min-
utes until the system is largely discharged.
• The DC auxiliary circuit is not completely voltage-free after shutdown, the voltage is merely low (U
DC
≤ 60 V),
meaning that a lethal shock can no longer occur if operators touch live parts in the DC intermediate circuit.
ATTENTION! Possible damage to the unit due to improper shutdown.
For standard shutdown, the power output must be 0 kW before the APU is taken out of operation using the off
switch. Use the LCS tool to reduce the output to 0 kW.
The DC isolating switch on the underside of the STPS must remain in the “ON” position and must
not be set to “OFF” under any circumstances.
1
Reduce the power output of the STPS 60-10 to 0 kW. To do this, open the LCS tool and access the Inverter
Manager.
2 Press the “Plant Stop” button at the top right of the LCS tool. The Inverter Manager will then lower the power out-
put of the STPS to 0 kW, open the AC contactor of the STPS and give the command to the SMA HV APU to dis-
connect from the DC path. Wait until you hear the audible opening of the contactors in the STPS and the
SMA HV APU. For more information, please consult the SMA product documentation or visit www.sma.de.
3
Disconnect the AC fuses of the STPS 60-10.
4 Now press the on-off switch “SWITCH”
17
on the SMA HV APU. The
green LED must then go out.
For systems with multiple STORAGE-67-TS-10s, each
SMA HV APU must be switched off.
5
On the APU, disconnect the DC cables
7.1
and
7.2
from the unit at the CHARGER connection (
12
/
13
).
6
Wait 15 minutes until the system is largely voltage-free, as it takes several minutes for the capacitors in the
inverter to discharge.
