Notes on grid connection
Grid Connection
NOTE!
In order to ensure a proper ground connection, all three GND ground terminals
must be tightened with the specified torque during installation.
NOTE!
When connecting the AC cable to the AC terminal, create loops of min.
4 in. (102 mm) with the AC cables.
IMPORTANT! The GND ground conductor of the AC cable must be laid so that
this is the last to be disconnected.
Cut GND ground conductors longer, for example, and make them into a loop.
If AC 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 AC cable
over the DC main switch or across the
DC main switch connection block.
Example: AC cable
If long AC or DC cables are laid in the
connection area in cable loops, fix the
cables to the lugs designed for this
purpose on the top and bottom of the
connection block using cable ties.
