13. Depending on the grid configuration, connect
the neutral conductor to connecting terminal
plate
N
(see Section 6.3.1 "Requirements for the
AC Connection", page 26).
14. Connect the conductors L1, L2 and L3 to the
terminals
L1
,
L2
and
L3
according to the label.
Ensure that the assignment is correct.

Danger of crushing when locking levers snap shut
The locking levers close by snapping down fast and hard.
• Press the locking levers of the connecting terminal plate for the AC cable down with your
thumb only. Do not grip the entire connecting terminal plate for the AC cable between
finger and thumb and keep fingers out from under the locking levers.
16. Ensure that the correct conductors are assigned to all the terminals.
17. Ensure that all locking levers of the connecting terminal plate are closed and all conductors
are tightly connected.
6.3.3
Connecting Additional Grounding
The inverter is equipped with a grounding terminal with two connection points on the DC side for

The grounding terminal is yellow/green and identified as follows:
• Equipment grounding terminal: symbol
• Grounding electrode conductor: labeling
GEC
Cable requirements:
☐ The cable must be designed in accordance with the local installation requirements and for
temperatures of over +90°C (+194°F).
☐ Cable type: copper wire
☐ Conductor cross-section: 10 mm² to 35 mm² (8 AWG to 2 AWG)
Requirement:
☐ The conduits must be correctly connected to the inverter.
