1. General
Using the Vacon Flange Mounting Kit, you can mount your Vacon NX AC drive through the cabinet wall
so that the control unit of the drive remains inside the cabinet.
The correct installation of the Flange Mounting Kit affects the IP protection class of the AC drive.
After the installation, the control unit is protected according to IP21 and the power unit according to
IP54 (unless the AC drive was originally IP21-protected). See figure below.
Cabinet
IP54
IP21
According to standard IEC 60529 (EN 60529), the IP54 AC drive enclosure provides protection against
dust and water sprayed from all directions. Limited ingress of both is permitted.

16. Apply the sealing tape attached around the opening along the edge. Place the tape so that it runs
inside
the screw holes.
The kit contains a greater amount of tape than what you might need. Only use such an amount of
tape required by the dimensions of the opening. See Figure 1.
17. Fit the AC drive in the opening.
NOTE: The AC drive will not fit in the opening in a straight position. Tip the converter positioning
the lower end first in the opening. See Figures 2 and 3.
