Inverter DC
Connection
The inverter is designed exclusively to
be connected and used with nongroun-
ded solar modules.
The solar modules cannot be grounded
at either the positive or negative pole.
IMPORTANT! Check the polarity and voltage of the solar module strings.
If DC cables are laid over the shaft of
the DC main switch, or across the DC
main switch connection block, they
could be damaged when the inverter
swivels in, or the inverter could be pre-
vented from swiveling in.
IMPORTANT! Do not lay the DC cable
over the DC main switch or across the
DC main switch connection block.
