7.3.3 Establishing Connection
1. Check the polarity of the DC voltage at the DC connec-
tions before connecting the PV system.
2. Install the connection plug/socket on the DC cable. Fol-
low the connection plug manual when doing this.
3. Insert the DC cable into the DC connections for the
solar inverter.
4. Check the installation.
þ
The PV module is now connected.
► Insert the wires of the AC cable into the pin insert con-
nections. Observe the correct phase sequence when
doing this.
► Tighten the screws of the pin insert to fix the wires in
place.

7.3.2 Connection of the PV modules
DANGER
Danger of death or severe injuries from
dangerous voltage
Dangerous voltages can be present at the
DC connections of the solar power inverter.
► Never disconnect the PV modules when
the solar power inverter is under load.
First switch off the grid connection so
that the solar power inverter cannot
feed energy into the grid. Then open the
DC switch.
► Secure the DC connections against be-
ing touched.
NOTE
► To ensure protection conforming to IP65
all unused connections and interfaces
must be closed using the covers on the
solar power inverter.
General instructions
The strings of the PV modules are connected to the DC
connections, see
Fig. 7.8, p. 30
Fig. 7.8.:
Location of DC connections
The negative DC pole of the string is connected to the DC-
MINUS connection; the positive DC pole to the DC-PLUS
connection, see
Fig. 7.9, p. 30.
The connections are
coded to prevent incorrect polarity.
