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. Refer to 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 FA09 or FA10 template.

The holes must match the holes in the frequency converter.

Insert 4 M10 pem studs (not supplied) in the mounting holes.

Cut out the 2 vent openings in the mounting plate using the dimensions in the FA09 or FA10 template.

The openings must match the upper and lower duct openings.

2.4 Preparing the Backplate

To create vent openings in the cabinet backplate to match the openings in the mounting plate, use the following steps. Refer to

Illustration 5 for FA09 frequency converters and Illustration 6 for FA10 frequency converters.

Procedure

Cut out the vent openings in the cabinet backplate using the dimensions in the FA09 or FA10 template.

The openings must match the mounting plate openings.

Drill screw holes (6 mm) around the vent openings.

The FA09 requires 6 holes around each vent opening, and the FA10 requires 8 holes around each. The holes must align

with the holes in the outer flanges of the ducts.

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).

2.6 Mounting the Frequency Converter

To install the mounting plate and frequency converter in the Rittal cabinet, use the following steps. Refer to Illustration 8.

Procedure

Remove the backing paper from the 2 self adhesive upper mounting plate gaskets.

Affix the gaskets around the upper opening, 1 on each side of the mounting plate.

Remove the backing paper from the 2 self adhesive lower mounting plate gaskets.

Affix the gaskets around the lower opening, 1 on each side of the mounting plate.

Attach the mounting plate to the cabinet rails, making sure that the pem studs face the front of the cabinet.

Remove the backing paper from the 2 seal plate gaskets.

Affix the gaskets to the seal plates, 1 per plate.

Fasten 2 M10x30 screws through the seal plates, 1 per plate, and into the M10 nuts at the lower end of the mounting plate.

Check that the screws are secure. The base of the frequency converter rests on the screws.

Slightly lean the top of the frequency converter forward and set the notches in the base onto the 2 screws.

Slowly push the top of the frequency converter back against the mounting plate until the top 2 pem studs line up with the

holes in the frequency converter.

Secure the top of the frequency converter using 2 M10 nuts.

Torque all fasteners to 19 Nm (170 in-lb).
