SMA 20000TL - Manual (Page 30)

Procedure:
1. Ensure that the circuit breaker is switched off from all three line conductors and that it cannot
be reconnected.
2. Ensure that there is no ground fault in the PV array.
3. Check whether the DC connectors have the correct polarity.
If the DC connector is equipped with a DC cable of the wrong polarity, the DC connector must
be configured again. The DC cable must always have the same polarity as the DC connector.
4. Ensure that the open-circuit voltage of the PV array does not exceed the maximum input
voltage of the inverter.
5. Connect the assembled DC connectors to the inverter.
☑ The DC connectors snap into place.
