6.3.3 AC2 (Generator/Grid)<br />
The distribution sub-panel of the generator/power distribution grid is connected to the AC2 output of<br />
the <strong>Sun</strong>ny Island.<br />
Single-phase parallel system<br />
In the case of single-phase parallel systems, also connect the generator or the grid to all<br />
slaves on AC2. The AC cables between all <strong>Sun</strong>ny Island and the generator/grid in a<br />
system must have the same size and length.<br />
Distributing loads and AC feed-in generators in multiple-phase systems<br />
Distribute the power of the feeding and loads as well as the AC feed-in generators as<br />
equally as possible on all system phases.<br />
Three-phase system<br />
Always install the master on phase L1, slave 1 on L2 and slave 2 on L3. This installation<br />
has a right-hand rotary field. The AC cables between all <strong>Sun</strong>ny Island and the generator/<br />
grid in a system must have the same size and length.<br />
The system does not monitor additional fuses. Check any additional fuses regularly!<br />
For connection, proceed as follows:<br />
Cable cross-section<br />
The maximum cable cross-section for connecting the generator is 16 mm2 .<br />
1. Sheathe the cable gland over the three-conductor cable and then insert the conductor through<br />
the cable opening into the <strong>Sun</strong>ny Island.<br />
2. Install the M25 cable gland (included in scope of delivery) in the "AC2 Gen/Grid" cable feedthrough.<br />
– Insert the cable gland with the thread in the cable opening.<br />
– Screw the counter nut onto the cable gland thread on the inside of the enclosure and tighten.<br />
3. Remove the protective insulation from each of the three conductors.<br />
4. Connect PE to the "AC2 Gen/Grid" according to the label.<br />
5. Connect N and L to the "AC2 Gen/Grid" according to the label.<br />
