Figure 39: Connection points for supply voltage
Position Designation
1 Transformer for internal power supply
2 Station subdistribution
3 Lighting
4 Outlet
5 Inverter
6 Communit
A Transformer circuit breaker
B Circuit breaker of the entire station subdistribution
C Circuit breakers of the station subdistribution devices
7.3 Disconnecting the Supply Voltages of the Station Subdistribution
The circuit breakers for the different devices of the MVPowerStation are located in the station subdistribution.
Procedure:
1. For disconnecting the inverters from the supply voltage, switch off the circuit breakers VoltageSupplySC1 and
VoltageSupplySC2.
2. For disconnecting the Communit and its lighting from the supply voltage, switch off the circuit breaker
VoltageSupplyLighting/Communit.
3. For disconnecting the optional fans from the supply voltage, switch off the circuit breaker Fan.
4. For disconnecting the outlet from the supply voltage, switch off the circuit breaker Socket.
5. For disconnecting the entire MVPowerStation from the supply voltage, switch off the main switch
VoltageSupplyPowerOutlet.
6. For disconnecting the transformer for internal power supply, switch off the transformer protective device.
