8 Recommissioning the Inverter
3. Tighten all connecting screws (TX 20, 3.5 Nm). Use
the new screws supplied for this. In case of STP
8000TL / STP 10000TL / STP 12000TL / STP
15000TL / STP 17000TL: Do not tighten the screws
in the indicated area. The dotted area remains
unequipped after the installation. In case of STP
15000TLEE / STP 20000TLEE: The indicated area
must also be equipped and the screws tighten.
4. Connect all connections on the AC-CON.
5. Only with STP 15000TLEE / STP 20000TLEE: If the new AC-CON is delivered without ferrite
bead, lead the old ferrite bead over the insulated conductors L1, L2, L3, and N to the new AC-
CON.
6. Plug the insulated conductors into the opening of the AC terminal block. When doing so,
ensure that the assignment is correct.
7. Only with STP 15000TLEE / STP 20000TLEE: Attach the ferrite bead with 2 cable ties (100 x
2.5 mm) to the insulated conductors of L1 and N. Cut off the ends of the cable ties.
8. Recommission the inverter (see Section 8, page 26).

1. Carry out the necessary tests according to the locally applicable laws, standards and
directives for the correct recommissioning after power assembly replacement. Take the
requirements for component replacements into account (see Section 2.2 "IMPORTANT
SAFETY INSTRUCTIONS", page 8).
2. Ensure that the grounding conductor in the inverter is correctly connected and functions
properly.
3. Mount the upper enclosure lid onto the enclosure and lightly fasten all screws.
