4.1 Connecting and disconnecting Solar Inverter
CAUTION
· Ensure proper mechanical and electrical installa-
tion before commissioning the Solar Inverter.
· Check the proper condition of the electrical lines.
· Always separate the grid connection first by
switching off the corresponding mains fuse and
then the solar generator side by quickly opening
the DC load break switch.
· The Tyco Solarlok connectors of the solar genera-
tor connection may not be disconnected while
under load. The DC load break switch must be
quickly switched to the switching position 0.
The Solar Inverter is supplied from the grid. The
Solar Inverter switches on automatically when suf-
ficient solar generator output is available. Corre-
sponding switch-on and switch-off thresholds have
been defined for this purpose.
Connecting
1. Switch on the grid connection with the external
circuit breakers.
2. Switch on the solar generator voltage by quickly
closing the DC load break switch (switching posi-
tion 1). The Solar Inverter takes up operation
when sufficient input voltage is available.
