Procedure

  1. Drill 6 mounting holes in the back of the frequency converter using the dimensions in the template.
  2. Insert 6 M10 pem self-clinching nuts (not supplied) in the mounting holes.
  3. Cut out the upper and lower vent openings in the mounting plate using the dimensions in the template.
    The openings must match the frequency converter vent openings.
  4. Drill 6 screw holes around each vent opening using the dimensions in the template.
    The holes must match the holes in the frequency converter and the inner flange of the back ducts.Danfoss-FA12-In-Back-Out-Back-Cooling-Kit (4) Danfoss-FA12-In-Back-Out-Back-Cooling-Kit (5)

Creating Vent Openings in the Backplate
To create upper and lower vent openings in the cabinet backplate, use the following steps. Use the dimensions in Figure 5 for 600 mm (24 in) cabinets, and Figure 6 for 800 mm (32 in) cabinets.

Procedure

  1. Cut out the vent openings in the cabinet backplate using the dimensions in the template.
    The openings must match the frequency converter and mounting plate vent openings.
  2. Drill 8 screw holes (6 mm) around each vent opening using the dimensions in the template.
    The holes must match the holes in the frequency converter and in the outer flange of the back duct. Danfoss-FA12-In-Back-Out-Back-Cooling-Kit (6)

Installing the Top Cover
To install the top cover, use the following steps. See Figure 7.

Procedure

  1.  Remove paper backing from the top gasket to expose the adhesive.
  2. Adhere the top gasket to the underside of the top cover.
  3. Remove the M5x14 screws (T25) surrounding the sides and back of the vent in the top of the frequency converter.
    Retain the screws. Fx11 converters have 6 screws; Fx12 converters have 7 screws.
  4. Loosen 3 M5x12 screws (T25) at the front of the vent in the top surface of the frequency converter.
  5. Slide the edge of the top cover plate under the 3 loosened screws, positioning the plate over the top vent.
  6. Secure the top cover plate with the M5x14 screws (T25) removed previously in step 3.

Installing the Bottom Cover

NOTICE
DRAIN OPENING

  • The bottom cover features a drain opening in the middle of the plate.
  • To drain moisture in wet or humid environments, attach nylon tubing with an interior diameter of 8 mm (0.3 in).
  • To seal the drain in dry environments, fasten a screw in the drain hole.
  • To install the bottom cover at the lower end of the cooling back channel, use the following steps. See Figure 8.

Procedure

  1. Remove the paper backing from the bottom gasket.
  2. Adhere the gasket to the upper side of the bottom cover.
  3. Position the bottom cover and gasket over the opening at the lower end of the cooling channel.
