SMA MEDIUM VOLTAGE POWER STATION 500SC-JP - Reconnecting the AC Side; Reconnecting the DC Side; Restarting the Inverter; Reconnecting the Supply Voltage of the Station Subdistribution

7.9.2 Reconnecting the AC Side
1. Reconnect the supply voltage and external voltages (see Section7.9.1, page103).
2. Reconnect the AC voltage of the MV transformer (see Section7.8, page102).
3. Switch on the AC disconnection unit in the inverter.
7.9.3 Reconnecting the DC Side
1. Insert all fuses and disconnection blades into all fuse holders of the inverter. Use an LV/HRC fuse extractor.
2. Screw on the protective covers over the fuses (torque: 5Nm).
3. Switch on the DC voltage in the DC main distribution or DC subdistribution (see documentation of the main or
subdistribution).
7.9.4 Restarting the Inverter
• Turn the key switch to Start.
7.10 Reconnecting the Supply Voltage of the Station Subdistribution
1. In case the transformer for internal power supply has been disconnected, switch on the transformer protective
device.
2. Switch on the main switch of the supply voltage VoltageSupplyPowerOutlet.
3. Switch on the circuit breakers of the inverters VoltageSupplySC1 and VoltageSupplySC2.
4. Switch on the circuit breaker of the Communit and lighting VoltageSupplyLighting/Communit.
5. Switch on the circuit breaker of the optional fans Fan.
6. Switch on the circuit breaker of the outlet Socket.
7. Switch on any additional supply voltages.
