User's Guide THEIA S String Inverters
Switch off the mains power supply (AC side, fuse) before connecting the
inverter.
Verify that galvanic isolation between the photovoltaic generator circuit
and the AC circuit is maintained by the way the cables are run.
Prior to connecting the inverter, verify that voltage is applied to the
generator-side DC terminal
Prior to connecting the inverter, verify that the DC voltage polarity is
correct
Wear insulating protective clothing and face protection if there is voltage
present at the DC input
Remove DC cable exclusively when inverter is out of operation
Ensure that wire cross sections and fuses conform to VDE 100 Part 430,
or the equivalent local standard.
Ensure that any network cables between two inverters are no longer than
30m
For DC cables, use a wire cross section of at least 2.5mm
Ensure that the AC cable resistance does not exceed 0.5Ω
Ensure that the max. DC voltage is not exceeded (see
Technical Data
)
Connect exclusively safety extra low voltage (SELV) on the contacts of
the external indicator
