Grid voltage 220 V ... 240 V
Wire the AC plug supplied as described in the Appendix under Mounting ⇒ AC plugs.
Grid voltage 100 V ... 127 V
DANGER!
Risk of death by electrocution! Never connect one of the phases L1, L2 or L3 to PE or N on
the mains grid side.
Notice
With a mains grid voltage of 100 V ... 127 V, the inverter can be connected between the L1,
L2 and L3 external conductors as follows:
2-phase mains grids
– N and L are connected between the L1 – L2 external conductors at the inverter side.
See ② and ③ in Fig. 12.
– One of the two connected external conductors is connected to PE at the inverter side.
This connection can be made within the AC plug or in an external junction box.
Fig. 12 shows an example of an inverter-side connection between L1 and PE:
Top: Connection
① in the AC plug ⑤
Bottom: Connection ④ in an external junction box ⑥ )
3-phase mains grids
– N and L are connected between the L1 – L2 or L1 – L3 or L2 – L3 external conductors at
the inverter side.
– One of the two connected external conductors is connected to PE at the inverter side.
This connection can be made within the AC plug or in an external junction box.
Fig. 12 shows an example of an inverter-side connection between L1 and PE:

Bottom: Connection ④ in an external junction box ⑥ )
The external conductor voltages are shown in Fig. 13.
1. Wire the AC plug supplied for the selected external conductors as described in the Appendix
Ä Appendix „Assembly“ on page 96.
2. Connect one of the two connected phases to PE at the inverter side. Make this connection
inside the AC plug or use an external junction box, as shown in Fig. 12.
3. Close the AC plug.
