SMA MEDIUM VOLTAGE POWER STATION 500SC-JP - Reconnecting the Inverter; Reconnecting the Supply Voltage and External Voltages

Connect and disconnect the AC voltage of the MV transformer
Only a duly authorized person is allowed to connect and disconnect the AC voltage of the MV transformer.
Procedure:
1. Unground (see documentation for the medium-voltage switchgear).
2. Switch the transformer panel and the ring circuit of the medium-voltage switchgear on (see documentation of the
medium-voltage switchgear).
7.9 Reconnecting the Inverter
7.9.1 Reconnecting the Supply Voltage and External Voltages
1. Close the measurement and disconnect terminals.
2. Switch on the motor-protective circuit-breakers of the grid
monitoring.
3. Connect any additional external voltage.
4. If the supply voltage has been disconnected downstream from the circuit breaker, switch the external circuit
breaker of the supply voltage on.
Tip: The external circuit breaker of the supply voltage is usually located in a subordinate distribution station.
5. If the supply voltage has been disconnected upstream from the
circuit breaker, switch the circuit breaker of the supply voltage
on.
