6 Electrical Connection SMA Solar Technology AG
Operating manual 43 SI44M-80H-13-BE-en-15
Cable requirements:
☐ Classification: CAT5e
☐ Type of plug: RJ45
Procedure:
1. Plug the black data cable into a free pin connector ComSync on the Sunny Island (see Section 6.6.4,
page 59).
2. Connect the other end of the black data cable to the Multicluster-Box (see Multicluster-Box documentation).
3. Ensure that the communication bus is closed at each end, e.g. with a terminator.
6.5.7.5 Connecting Control and Measuring Cables of the Multicluster-Box
For a multicluster system, the Multicluster-Box communicates control and measuring data with the 3 Sunny Island
inverters of the main cluster via 3 red data cables (see Multicluster-Box documentation). The red data cables are part
of the scope of delivery of the Multicluster-Box.
Cable requirements:
☐ Cable length for BatVtgOut, DigIn, and BatTemp: less than 30 m
Procedure:
• Plug the red data cables into the pin connector BackupVtgCur on the Sunny Island units of the main cluster (see
Section 6.6.4, page 59). Connect the master with the connection Mstr./L1 , slave 1 with the connection Slv1./
L2 and slave 2 with the connection Slv2./L3 on the Multicluster-Box.
6.5.7.6 Connecting the Data Cables for Multicluster Communication
In a multicluster system, the masters of the various clusters communicate with each other (see Multicluster-Box
documentation). An SI‑SYSCAN.BGx communication interface must be installed in each master when using a
Multicluster-Box. If the Sunny Island was ordered with the
Communication for multicluster system order option,
SI‑SYSCAN.BGx is installed in each master.
