Compatibility of assemblies
The assemblies of the spare-part set NR-STP200-ACCON and NR3-STP200-ACCON are not
compatible with the TP-ACCON-XX.XX assembly.
• Before replacing the assembly, ensure that the assembly is only replaced with a
compatible assembly. Refer to the assembly's type label to find out which assembly is
installed in the inverter.
There are assemblies on this assembly with a safety extra-low voltage circuit (SELV circuit). To
ensure the safety of the circuits, an optical inspection must be carried out before installation.
