10. Connect the conductor ends to the communication terminal in the inverter at screw terminals
2, 3, 5 and 7 (torque: 0.23 Nm). Observe the permitted cable route (see Section5.1 "Inverter
Connection Area", page22) and the contact pin assignment as follows:
11. Make sure no jumpers are set at the jumper slot for communication.

Danger to life due to electric shock in case of incorrect cable insulation
In case of incorrect cable insulation, high voltages may occur on the cable outside the inverter.
• Guide the cable in the inverter through the insulating hose. The insulating hose must
completely cover the cable and the conductors inside the inverter enclosure.
• Cut the insulating hose to the required length, as necessary.
• Fix the insulating hose in position at the beginning and end of the cable, as necessary,
using cable ties. Cut off the ends of the cable ties. This will prevent the ends of the cable
ties causing damage to hot components in the inverter.
