SMA MEDIUM VOLTAGE POWER STATION 500SC-JP - Opening the Drain Orifices in the Inverter Compartment; Mounting the Exhaust Duct under the Inverters

5.3.1.3 Opening the Drain Orifices in the Inverter Compartment
The drain orifices in the inverter compartment are sealed with plugs and must be opened prior to installation.
Figure 28: Position of the drain orifices
Position Designation
A Drain orifice
Procedure:
1. Open the inverter compartment (see Section12.1, page159).
2. Disassemble the panels of the inverters (see Section12.3.1.2, page164).
3. Remove the plugs from the drain orifices in the floor of the station container.
4. Close the inverter compartment (see Section12.1, page159).
5.3.2 Mounting the Exhaust Duct under the Inverters
The exhaust ducts must be mounted under the inverters prior to installation. The exhaust duct is positioned on the
bottom side of the ventilation plate. The warm exhaust air from the inverters is evacuated through the exhaust ducts
under the MVPowerStation.
Procedure:
1. Open the inverter compartment (see Section12.1, page159).
2. Disassemble the panels on the inverter cabinet (see Section12.3.1.2, page164).
3. On the front side of the inverter, remove the ventilation plate from the inverter.
4. Remove the screws of the cover plate under the inverter.
5. Remove the cover plate from the station container. The cover plate and the screws are no longer needed.
6. Push the ventilation plate into the inverter.
7. Loosen the four screws on the exhaust duct on the bottom side
of the ventilation plate.
