Note

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. 7.

–

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. 7 shows an example of an inverter-side connection between L1 and PE:

Above: connection ① in an AC plug ⑤

Below: 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.

–

Connect the external conductor on the inverter side to PE: as above.

–

Fig. 7 as above.

The external conductor voltages are shown in Fig. 8.

1. Wire the AC plug supplied to match the selected external conductors, as described in the

Appendix under Mounting ⇒ AC plugs. Do not yet close the AC plug.

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. 7.
