15. Connect the wire ends to the communication terminal in the inverter at screw terminals 2, 3, 5
and 7 (torque: 0.23 Nm) (for position of the communication terminal, see Section 5.1).
Observe the permitted cable route (see Section 5.1) and the pin assignment as follows:
16. Make sure that there are no jumpers in the communication jumper slot (position of jumper slot
for communication, see Section 5.1).

Danger to life due to electric shock in case of incorrect cable insulation
If a cable is not correctly insulated, high voltages may occur on the cable outside the inverter.
• Lead the cable into the inverter through the
silicone tube. The silicone tube must completely
cover the cable and the wires inside the inverter
enclosure.
• Cut the silicone tube to the required length, as
necessary.
• Fix the silicone tube in position with cable ties
at the beginning and end of the cable, as
necessary. Trim the ends of the cable ties. This
will prevent the ends of the cable ties causing
damage to hot components in the inverter.
