GENERAL
Using the Vacon Flange Mounting Kit, you can mount your Vacon NX frequency converter 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 frequency
converter. After the installation, the control unit is protected according to IP21 and the power unit
according to IP54 (unless the frequency converter was originally IP21-protected). See figure below.
According to standard IEC 60529 (EN 60529), the IP54 frequency converter enclosure provides
protection against dust and water sprayed from all directions. Limited ingress of both is permitted.

MOUNTING
MOUNTING PROCEDURE
1. Make an opening in the cabinet door for the flange (collar) installation using the dimensions
given in Vacon NX User's manual, chapter 5.
2. Attach the sealing tape around the opening. See Figure 1 for how to bend the tape at the corners
of the opening (1) and place the tape so that it runs
inside the screws (2).
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.
3. Fit the frequency converter in the opening.
NOTE: The frequency converter will not fit in the opening in a straight position. Tip the converter
positioning the lower end first in the opening. See Figures 4 and 5.
Fix the converter on the plane with the screws attached.
