7. Connect the conductors to the 3-pole terminal block
according to the circuit diagram, depending on the
operating mode (see Section 6.5.3, page 32).
Ensure that the conductors are plugged completely
into the terminal points (round openings) up to their
insulation.
8. Stick the 3-pole terminal block with the connected conductors into the MFR slot on the
communication assembly in the inverter.
9. Ensure that the terminal block is securely in place.
10. Ensure that all conductors are correctly connected.
11. When using the cable glands, tighten the swivel nut of each cable gland hand-tight. This will
secure the conductors.
12. Ensure that the conductors sit securely in the terminal points.
Useful hint: To release the conductors from the terminal block, open the terminal points using a
suitable tool.

Connecting the Network Cables

Danger to life due to electric shock
Overvoltages (e. g. in the case of a flash of lightning) can be further conducted into the building
and to other connected devices in the same network via the network cable if there is no
overvoltage protection.
• Ensure that all devices in the same network are integrated in the existing overvoltage
protection.
• When laying the network cable outdoors, attention must be given to suitable overvoltage
protection at the network cable transition from the inverter outdoors to the network inside the
building.
• The Ethernet interface of the inverter is classified as "TNV-1" and offers protection against
overvoltages up to 1.5 kV.
Additionally required material (not included in the scope of delivery):
☐ For the use of conduits: conduits: 27 mm (1 in) or smaller with suitable reducing bush
☐ Rain-tight conduit fitting for wet locations complying with UL 514B: 27 mm (1 in) or smaller
with a proper reducing bush
☐ Network cables
☐ Where required: Field-assembly RJ45 connector.
