5.4.4 Generator Start with a Single Contact
The Sunny Island 3324/4248 can automatically start generators that can be started/
stopped using a single contact. This is done by the generator control relay
(GenRequest-Relay) integrated into the Sunny Island 3324/4248. The autostart
(single contact start) generator is directly connected to the "G_Req“ connection
terminals of the Sunny Island 3324/4248. Further information on parameter settings
and other methods of starting generators can be found in sections 8.5 "Operation
with a Generator" (Page 74) and 10.2 "PV Stand-alone System with Generator"
(Page 90).
1. Install an M20 metric-thread cable screw connection (included in delivery) in
one of the "Additional connections" cable feed-throughs (see figure Page 31).
- Remove the dummy plug covering the chosen cable feed-through in the
housing.
- Insert the cable screw connection thread into the opening in the housing.
- Screw the appropriate M20 counter-nut onto the cable screw connection
thread inside the housing.
2. Remove the protective insulation from the conductors and fit a suitable cable
end sleeve to the exposed ends of each conductor.
