Installing the DC filter assembly
1. Place the new DC-EMV onto the fixing domes in the inverter and carefully press until the fixing
domes snap into place. While doing so, ensure that the cable on the right edge of the
assembly is in the projection.
2. Tighten all the connecting screws (TX20, torque:
3.5 Nm). Use the new screws supplied for this.
3. Insert the ESS pin connector in the bracket and
attach using the clamping clip.
4. Lead all DC-EMV cables with the cable glands through the enclosure opening to the ESF.
5. Ensure that the cable glands are securely in place in the enclosure opening.
6. Connect all DC-EMV cables:
• Connect the cables to the ESF. When doing so,
ensure that the assignment is correct.
• Plug the 8-pole plug into the DC-EMV.
