7 Mounting the Power Unit
11. 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:
4 mm (5⁄32 in)).
12. Commission the inverter (see inverter manual). The inverter ramp-up lasts up to 20 minutes. All
relevant information is transferred from the Connection Unit to the Power Unit, and the
Power Unit may also be updated.
13. Wait 20 minutes before connecting the inverter to the communication network to avoid the
transfer of false data after the set-up.
14. 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).
15. 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.
