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.

2.3 Creating Vent Openings in the Mounting Plate
To create upper and lower vent openings in the mounting plate, use the following steps. Use the dimensions in Illustration 3 for 600
mm (24 in) cabinets, and Illustration 4 for 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 upper and lower vent openings in the mounting plate using the dimensions in the template.
The openings must match the frequency converter vent openings.
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.

2.5 Installing the Top Cover
To install the top cover, use the following steps. See Illustration 7.
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. FA11 converters have 6 screws; FA12 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).
