Position Designation
A SMA String-Monitor
B Inverter (example)
Procedure:
1. Lead the Ethernet cable through the corresponding enclosure opening (see Section 6.1, page 25
) into the DC subdistribution (see Section 12.1, page 62).
2. Prepare the Ethernet cable for connection as follows:
• Strip 44 mm cable sheath off the end of the connection cable which is to be attached to
the DC subdistribution.
• Shorten the cable shield to 15 mm.
• Fold the surplus cable shield back over the cable sheath.
3. Press the Ethernet cable with the cable shield into the shield clamp. The cable shield must be
clamped under the shield clamp as completely as possible.
4. Connect the Ethernet cables to the LSA+ terminals on the electronic assembly using the LSA+
insertion tool:
• To connect the communication output, connect all eight conductors of the Ethernet cable
to the electronic assembly at terminal X7 (see Section 4.4, page 17) according to the
following table. Trim any overlapping conductors.
