SMA SC 500CP XT Installation - Manual (Page 35)

Requirements:
☐ The connected load must operate with a voltage of 230 V
AC
or 24 V
DC
.
☐ The connected load must draw a current of 10 mA to 6 A.
Procedure:
1. Disassemble the panels (see Section 7.2.1, page 40).
2. Insert the cables (see Section 7.1, page 40).
3. Connect the cables in accordance with the circuit diagram (see Section 7.4, page 49).
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 7.2.1, page 40).
5.6.10 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 7.2.1, page 40).
2. Insert the cables (see Section 7.1, page 40).
3. Connect the cables in accordance with the circuit diagram (see Section 7.4, page 49).
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 7.2.1, page 40).
5.6.11 Connecting the Transformer Protection
The inverter is equipped with a terminal for monitoring the MV transformer. Under fault conditions, the inverter is
immediately switched off. To use the transformer monitoring, an external supply voltage of 230 V/50 Hz must be
provided in the MV transformer.
Cable requirement:
☐ The cable used must be shielded.
Procedure:
1. Disassemble the panels (see Section 7.2.1, page 40).
2. Insert the cables (see Section 7.1, page 40).
3. Connect the cables in accordance with the circuit diagram (see Section 7.4, page 49).
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 7.2.1, page 40).
