2 Installation
2.1 Safety Information
NOTICE
QUALIFIED PERSONNEL
Only qualified, Danfoss authorized personnel are allowed to install the parts described in these installation instructions.
Disassembly and reassembly of the frequency converter must be done in accordance with the service guide.
Use the standard fastener torque values from the service guide, unless the torque value is specified in these instructions.
WARNING
DISCHARGE TIME (40 MINUTES)
The frequency converter contains DC-link capacitors, which can remain charged even when the frequency converter is not pow-
ered. High voltage can be present even when the warning LED indicator lights are off. Failure to wait 40 minutes after power has
been removed before performing service or repair work can result in death or serious injury.
Stop the motor.
Disconnect AC mains and remote DC-link power supplies, including battery back-ups, UPS, and DC-link connections to other
frequency converters.
Disconnect or lock the motor.
Disconnect any brake option.
Disconnect any DC connector option.
Wait 40 minutes for the DC-link capacitors to discharge fully.
Before performing any service or repair work, measure the voltage level to verify that the capacitors are fully discharged.
WARNING
ELECTRICAL SHOCK HAZARD
The frequency converter contains dangerous voltages when connected to mains voltage. Improper installation, and installing or
servicing with power connected, can cause death, serious injury, or equipment failure.
Only use qualified electricians for the installation.
Disconnect the frequency converter from all power sources before installation or service.
Treat the frequency converter as live whenever the mains voltage is connected.
Follow the guidelines in these instructions and local electrical safety codes.
NOTICE
ELECTROSTATIC DISCHARGE
Electrostatic discharge can damage components.
Ensure electrostatic discharge before touching internal frequency converter components, for example by touching a groun-
ded, conductive surface or by wearing a grounded armband.
2.2 Installation Overview
NOTICE
APPLYING GASKETS
This kit contains self-adhesive gaskets to ensure a proper seal between metal parts.
Before affixing a gasket, check that the part matches the gasket and that no holes are covered.

2.3 Creating Vent Opening in the Mounting Plate
To create mounting holes and a back vent opening in the mounting plate, use the following steps. Use the dimensions in Illustration
3for FA11 frequency converters in 600 mm (24 in) cabinets, and Illustration 4 for FA11 frequency converters in 800 mm (32 in)
cabinets. Use the dimensions in Illustration 5 for FA12 frequency converters in 800 mm (32 in) cabinets.
Procedure
Drill 6 mounting holes in the back of the frequency converter using the dimensions in the template.
Insert 6 M10 pem self-clinching nuts (not supplied) in the mounting holes.
Cut out the vent opening in the mounting plate using the dimensions in the template.
The opening must match the frequency converter vent opening.
Drill 6 screw holes around the vent opening using the dimensions in the template.
The holes must match the holes in the inner flange of the back duct.

2.5 Installing the Top Cover
To install the top cover, use the following steps. See Illustration 8.
Procedure
Remove paper backing from the top gasket to expose the adhesive.
Adhere the top gasket to the underside of the top cover.
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.
Loosen 3 M5x12 screws (T25) at the front of the vent in the top surface of the frequency converter.
Slide the edge of the top cover plate under the 3 loosened screws, positioning the plate over the vent in the top of the
frequency converter.
Secure the top cover plate with the M5x14 screws (T25) removed previously in step 3.
Torque all screws to 2.3 Nm (20 in-lb).

2.6 Assembling the Bottom Duct
The bottom duct is a telescopic duct that collapses to simplify installation. To assemble the duct before installation, use the follow-
ing steps. Refer to Illustration 9.
Procedure
Cut the strip of ribbed EPDM rubber seal into 2 pieces of 990 mm (39.0 in).
Peel the paper off the self-adhesive seals. Place 1 strip on the outside bottom edge of the inner sleeve of the duct, and
1 strip on the upper inside edge of the outer sleeve of the duct.
