Connecting the solar modules (DC)
DANGER
Electric shock
Potentially fatal voltages are present at the DC
connections of the inverter. When light falls on
the solar modules, they immediately start to
generate electricity. This also happens when
light does not fall directly on the solar modules.
► Never disconnect the inverter from the solar
modules when it is under load.
► Turn the AC/DC disconnector to the OFF
position.
► Disconnect the connection to the grid so
that the inverter cannot feed energy into the
grid.
► Disconnect the inverter from all AC and DC
voltage sources. Make sure that none of the
connections can be restored accidentally.
► Ensure that the DC cables cannot be
touched accidentally.

Connecting the solar modules (DC)
1. Use a red cable for DC+ and a black cable for DC–.
Use a voltmeter to check the polarity.
2. Turn the AC/DC disconnector to the OFF position.
3. Remove the sealing caps from the DC connections and
store in a safe place.
Do not remove the sealing caps from the unused DC con-
nections.
