SMA MEDIUM VOLTAGE POWER STATION 500SC-JP - Connecting the Cable for Remote Shutdown; Connecting the Cable for the Status Report of the Insulation Monitoring; Connecting the Cable for the Status Report of the AC Contactor Monitoring

4. Secure the cables on the cable support rail. This will prevent the cables from being pulled out inadvertently.
5. Mount the panels (see Section12.3.1.2, page164).
5.7.2.6 Connecting the Cable for Remote Shutdown
The remote shutdown enables the inverter to be switched off from a distance, e.g. from a control room. The function of
the remote shutdown is similar to the stop function of the key switch.
Shortfall of external supply voltage
If there is an external supply voltage between 18.5V to 24.0V, the inverter will continue to operate in its current
operating state. If the external supply voltage falls below 18.5V, the inverter switches from the current operating
state to the operating state "Stop". If the temperature inside the inverter exceeds the temperature limit, a supply
voltage of 20.0V to 24.0V must be present to continue operating the inverter in its current operating state.
Temperature limit: +60°C
• Ensure that the external supply voltage is between 20.0V and 24.0V.
Procedure:
1. Disassemble the panels (see Section12.3.1.2, page164).
2. Insert the cables (see Section12.4.3, page171).
3. Connect the cables in accordance with the circuit diagram (see Section12.6, page175).
4. Secure the cables on the cable support rail. This will prevent the cables from being pulled out inadvertently.
5. Mount the panels (see Section12.3.1.2, page164).
