2 Installation
2.1 Safety Information
NOTICE
QUALIFIED PERSONNEL
Only qualified 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 corresponding service guide.
Use the standard fastener torque values from the service guide, unless the torque value is specified in these instructions.
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.
WARNING
DISCHARGE TIME (20 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 indicator lights are off.
Failure to wait 20 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, permanent magnet type motors, and remote DC-link supplies, including battery back-ups, UPS, and
DC-link connections to other frequency converters.
Wait 20 minutes for the capacitors to discharge fully before performing any service or repair work.
Measure the voltage level to verify full discharge.
NOTICE
ELECTROSTATIC DISCHARGE
Electrostatic discharge can damage components.
Ensure discharge before touching internal frequency converter components, for example by touching a grounded, conduc-
tive surface or by wearing a grounded armband.

2.3 Preparing the Mounting Plate
To create mounting holes and vent holes in the mounting plate, use the following steps. Use the dimensions in Illustration 3 for
FA09 frequency converters, and Illustration 4 for FA10 frequency converters.
Procedure
Drill 4 mounting holes in the mounting plate using the dimensions in the template.
The holes must match the holes in the frequency converter.
Insert 4 M10 pem nuts (not supplied) in the mounting holes.
Cut out the vent opening in the mounting plate using the dimensions in the template.
The openings must match the upper duct opening in the frequency converter.

2.4 Preparing the Backplate
To create a vent opening in the cabinet backplate to match the opening in the mounting plate, use the following steps. Use the
dimensions in Illustration 5 for FA09 frequency converters, and Illustration 6 for FA10 frequency converters.
Procedure
Cut out the vent opening in the cabinet backplate using the dimensions in the template.
The vent opening must match the mounting plate opening.
Drill screw holes (6 mm) around the vent opening using the dimensions in the template.
The FA09 requires 6 holes around the vent opening, and the FA10 requires 8 holes around the opening. The holes must
align with the holes in the outer flanges of the back vent.

2.5 Installing the Top Cover
To install the top cover of the cooling kit, use the following steps. See Illustration 7.
Procedure
Remove the paper backing from the top cover gasket to expose the adhesive.
Adhere the top cover gasket to the underside of the top cover.
Remove 8 M5x14 screws (T25) surrounding the sides and back of the vent in the top of the frequency converter. Retain the
screws.
Remove 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 under the 3 loosened screws, positioning the cover over the vent in the top of the frequen-
cy converter.
Secure the top cover to the frequency converter with the M5x14 screws (T25) removed previously in step 3.
Torque all screws to 2.3 Nm (20 in-lb).
