Wiring the Inverter
AC wiring can be separated into 3-phase (L1, L2, L3), N, and PE. The following earthing congu-
rations are allowed. IT is not allowed. Please see the appendix for further explanation of these
earthing systems.
TN-S TN-C TN-C-S TT IT
Yes Yes Yes Yes No

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

6.2.2 AC bayonet connectors for 10 TL, 15 TL, 20 TL
The AC bayonet connectors are 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 6.5 to assemble the cable and bayonnet connector.
52.5 mm (PE 57.5 mm)
10 mm
Figure 6.3.: AC cable stripping requirements for 10 TL, 15 TL, and 20 TL
NOTE
For lines with a cable sheath diameter from 16 mm to 20 mm, the cable
gland must be adapted accordingly. To do this, cut out the inner section of
the blue sealing ring.
In Figure 6.5, the Amphenol C connector shown can be mated with the 10 TL / 15 TL / 20 TL
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.
