the left). There will be terminal blocks instead, in case the Sunny Island was
ordered without DC circuit breakers.
•
Terminals for generator start via relay K1
•
Terminals for generator contactor via relay K2
•
Terminals for grid contactor via relay K3
•
Terminals for additional switchable components such as wind energy convert-
ers, ohmic/inductive loads (via relays K1 to K8), freely configurable
•
Terminals for battery room fan via relay K7
•
Terminals for battery acid circulation via relay K8
If the relays K1, K2, K7 and K8 are not used for their special tasks, they
can also be freely configured.
The terminals K1 to K8 can only be used if they have been equipped with
their respective relays/modules optionally available.
•
Terminals for the measurement of generator voltage and current
•
Grid connection (at F2:L and F2:N of the automatic circuit breaker as well as
at the PE terminals on the right)
