SMA STP 15000TL - Manual (Page 13)

Symbol Explanation
Operating principle of the ESS:
• If the ESS is plugged in, the DC electric circuit is closed.
• If an acoustic signals sounds and the display shows an error
message that prohibits removing the ESS, wait until dark. The ESS
can only be removed once it is dark.
• If no acoustic signal sounds and the display does not show an
error message, the DC electric circuit may be interrupted. To
interrupt the DC electric circuit, you must perform the following steps
in the given order:
– Remove the ESS.
– Unlock and remove all DC connectors.
Danger to life due to high voltages in the inverter; observe the waiting
time of 20 minutes.
High voltages that can cause lethal electric shocks are present in the live
components of the inverter. Prior to performing any work on the inverter,
disconnect it from all voltage sources as described in this document (see
Section 10, page 48).
