13. Plug the terminal block with the connected AC
conductors into the AC-out slot in the

14. If applicable, plug the terminal block with the
connected cable for secure power supply operation
into the SPS slot in the Connection Unit, and tighten
(torque: 1.7 Nm ± 0.3 Nm (15.05 in-lb ± 2.65 in-
lb)) with a flat-blade screwdriver (blade width:
3.5 mm).
15. Commission the inverter (see inverter manual). The starting process of the inverter will take up
to 20 minutes since information is transferred from the Connection Unit to the Power Unit, and
the Power Unit may also be updated. Through the replacement of the Power Unit, the inverter
has been assigned a new serial number. The new serial number can be found on the type
label of the new Power Unit.
16. Set the correct country data set (see manual of the inverter).
17. If the inverter is registered in a communication product (e.g., Sunny Portal), replace the inverter
in the communication product (see installation manual "Replacement of SMA Devices in
Systems with Communication Products" at www.SMA-Solar.com).
18. If the inverter firmware could not be updated prior to replacing the Power Unit and the inverter
is not yet equipped with the current firmware version, perform a firmware update (see manual
of the inverter).
19. If a firmware update has been carried out, ensure that all parameters have been transferred
correctly and that the inverter feeds grid-compliant current into the utility grid.
