5.3.2 AC Output
The stand-alone grid sub-distribution (e.g. loads, PV generator (Sunny Boy), wind
turbine (Windy-Boy)) is connected to the AC output of the Sunny Island 3324/4248.
If you wish to provide separate protection for an individual load circuit, then use a
maximum 16 A, B-type circuit breaker. In the case of a short circuit, the Sunny Island
3324/4248 can still trigger these types of automatic breakers:
1. Install an M25 metric-thread cable screw connection (included in delivery) in the
"AC output" cable feed-through (see figure Page 31).
- Remove the dummy plug covering the cable feed-through.
- Insert the metric-thread cable screw connection into the opening in the
housing.
- Screw the counter-nut onto the cable screw connection thread inside the
housing.
2. Remove the protective insulation from each of the three conductors and fit a
suitable cable end sleeve to the exposed ends of each conductor.
3. Feed the three-conductor cable through the metric-thread cable screw
connection into the housing of the Sunny Island 3324/4248.
