Strip off the insulation of all four AC cable
conductors. The protective conductor (PE) must be
longer than the grid wires.
1. Verify that the nominal voltage of the inverter
matches the grid voltage.
2. Ensure that the main circuit breaker is released,
and take precautions to prevent reconnection.
3. Open the cover of the installation area.
4. Insert the cable through the AC cable gland to
the terminal block.
5. Connect the grounding conductor (PE) and the
three grid wires (L1, L2, L3) to the terminal block
with the respective markings.
6. Optional: Make an extra grounding conductor
connection at the secondary PE grounding points
using the external device grounding bolt
delivered with the inverter ((see Section 9.4,
page 48)).
7. All conductors must be properly attached with
the correct tool (screwdriver bit, length min.
50 mm) and correct torque, see Section 9.4,
page 48.

5.10 Ethernet Connections

When used outdoors, make sure to use a suitable
cable (see Section 9.6 "Technical Data of the
Communication Interface", page 50).
If the cable is very stiff, an intermediate terminal
should be used to achieve greater fexibility of the
cable before it is connected to the inverter. For some
cables, it may be sufcient to remove the outer hard
sheath from the part of the cable that is inserted into
the inverter enclosure. In this way, the RJ45 Ethernet
connectors mounted on the printed circuit boards are
protected against excessive stress, which could lead
to damages or problems with the connection.
Installation Guide
Procedure:
1. Do not remove the RJ45 connector on the
Ethernet cable.
2. Run the cables through the cable glands in the
base of the inverter (see the following fgure).
3. Cut slice in rubber grommet. Place the grommet
in the gland to ensure proper seal.
4. Plug into the Ethernet connector.

5.11 PV Connection

5.11.1 External PV Array Junction
Boxes
PV strings must be connected to the DC input via an
external PV array junction box. The PV array junction
box connects the PV strings of the PV array and
protects the individual strings against overcurrent
with appropriate fuse protection.
INFORMATION
The same number and type of modules must be
connected to all PV strings connected to the PV
array junction box. In addition, all connected
modules must have the same orientation.
INFORMATION
Observe correct fuse rating. Consult the
module manufacturer's manuals for information
on correct string fuse rating.
INFORMATION
Use a suitable voltage detector that can
measure up to 1000 V DC. Verify the polarity
and maximum voltage of the PV arrays by
measuring the PV open-circuit voltage.
