12. Remove the DC EMC assembly from the inverter. When doing so, only hold the assembly by
the handling areas (see Section 6.2, page 17) and ensure that the fan located on the rear
side of the carrier plate does not damage the DST assembly in the inverter.
13. If necessary, replace the DST assembly now (see Section 7, page 18). If only the DC-EMC

A Touch only the assembly on the marked areas or on the sheet metal located
underneath the assembly.

handling.
The remaining areas may not be touched. The assembly can be damaged through touching.
Procedure:
1. Align the assembly and insert it into the inverter. Touch the assembly only at the handling
areas. Ensure that the spacers match the holes in the mounting plate and that the cable is not
trapped beneath the mounting plate.
2. Tighten the 4 assembly connecting screws (TX20, torque: 3.5 Nm (31.0 in-lb)).
3. Insert the cables (red, light blue, white, green, black and purple) into the terminals at the top
and bottom of the assembly and ensure that all cables are firmly seated.
