2. Insert the PE conductor, N conductor and L conductors (L1, L2 and L3) into the OT terminal,
insert them into the corresponding terminals of the AC connector in the order as shown by
the following arrows, and tighten the screws with the supplied hex key with a suggested Torque
of 2.0 Nm
3. Secure the terminal block with a plastic clamp, screw the threaded sleeve body onto the AC
connector, and tighten threaded nut.
4. Insert the AC connector into the output terminal of the AC connector corresponding
to the inverter and turn clockwise to tighten.
5. If required, you can connect a second protective conductor as equipotential bonding.
VI. DC connection
1. Please refer to “DC Connector Installation Guide”.
2. Before DC connection, insert the DC plug connectors with
sealing plugs into DC input connectors of the inverter to
ensure protection degree.

Make sure PV modules have good insulation against ground.
On the coldest day based on statistical records, the Max. open-circuit voltage of the PV modules
must not exceed the Max. input voltage of the inverter.
Check the polarity of DC cables.
Ensure that DC switch has been disconnected.
Do not disconnect DC connectors under load.
