AC wiring can be separated into 3-phase (L1, L2, L3), N, and PE. The following earthing congu-
rations are allowed. IT is not allowed. Please see the appendix for further explanation of these
earthing systems.

NOTE
TT ist not recommended. Have to besure the voltage of N is very close to
PE (< 20 V

In Figure 5.5, the Amphenol C16-3 AC connector shown can be mated with the inverter‘s AC plug.
After disassembly of the connector, please adhere to the correct polarity for proper AC wiring (this
product allows either positive or negative phase sequence). That means the sequence of L1-L3
can be adjusted and the N and PE must be connected.
5.2.1 ACbayonetconnector
The AC bayonet connector is approved for cable sheath diameters between 11 mm and 20 mm.
To install an AC cable, rst strip the voltage free line and cable ends as shown below and then
follow the sequence in Figure 5.5 to assemble the cable and bayonnet connector.
