SMA MEDIUM VOLTAGE POWER STATION 500SC-JP - Connecting the Data Cable of the Sunny String-Monitor; Completion Work; Closing the Base Plates on the Inverter

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).
5.7.2.9 Connecting the Data Cable of the SunnyString-Monitor
For an optimum supply voltage, it is recommended to connect two insulated conductors each in the terminals of the
supply voltage and of the grounding.
Cable requirements:
☐ The supply voltage and the communication connection must be combined in one cable.
☐ The cable used must be shielded.
☐ Recommended cable type: Li2YCYv(TP)4x2x0.5mm².
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).
5.8 Completion Work
5.8.1 Closing the Base Plates on the Inverter
Requirement:
☐ All cables must be inserted in and connected to the MVPowerStation.
Procedure:
1. Insert the base plates under the inverter. The base plates must be aligned as close as possible to each other.
2. Tighten the base plates. Ensure that the enclosure openings
close tightly.
