Danfoss FR7 VACON NXP Air Cooled Instruction Manual

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 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.
Installation Instruction

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.

INSTALLATION

These instructions guide you through the installation of the Flange Mounting Kit that you have purchased for your FR7, FR8 or FR9 size AC drive.

MOUNTING

MOUNTING PROCEDURE

Make an opening in the cabinet door for the flange (collar) installation using the dimensions given in VACON® NX User’s manual, chapter 5.
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.
Fit the AC drive in the opening.
NOTE! The AC drive will not fit in the opening in a straight position. Tip the drive positioning the lower end first in the opening. See Figures 2 and 3.

Fix the AC drive on the plane with the screws included in the kit (FR7: M5 screws / FR8: M6 screws, FR9: M5 screws).

INFORMATION STICKER

Each Flange Mounting Kit delivered by the factory includes a sticker (shown below). Please check IP54/Collar (1) and mark the installation date (2) on the sticker. Finally, attach the sticker on the drive.
