Installation

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 regulations.

DISCHARGE TIME (20 MINUTES)
The frequency converter contains DC-link capacitors, which can remain charged even when the frequency converter is not powered. 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 backups, 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.
• To verify full discharge, measure the voltage level.

ELECTROSTATIC DISCHARGE

• Electrostatic discharge can damage components.
• Ensure discharge before touching internal frequency converter components, for example by touching a grounded, conductive surface or by wearing a grounded armband.

Installing the Base Plate
Use the following steps to install the base plate. See Illustration 4.

Procedure

1. Unfasten 9 M5x12 screws (T25) from the cable access plate (gland plate), and remove the plate from the bottom of the frequency converter.
   Keep the cable access plate and screws for reinstallation.

2. Adhere the base plate gasket to the underside of the base plate.

3. Fasten the bottom bracket to the upper side of the base plate using 2 M5x12 screws (T25) from the kit.

4. Position the base plate at the bottom of the frequency converter.

5. Secure the base plate using 6 M5x12 screws (T25) from the kit.

Installing the Bottom Cover
Use the following steps to install the bottom cover . See Illustration 4.

Procedure

1. Adhere the bottom cover gasket to the upper surface of the bottom cover.
   If mounting the frequency converter on a pedestal, install the bottom cover after the pedestal is attached.

2. Position the bottom cover over the opening in the base plate at the lower end of the cooling channel.

3. Secure the bottom cover using 6 M5x16 screws (T25) from the kit.

Installing the Cable Entry Plate
The cable entry plate provides cable entry and cable termination points. The plate is installed to maintain the IP21/Type 1 or IP54/ Type 12 protection rating. To install the cable entry plate, use the following steps. See Illustration 6.

Procedure

1. Create cable entry holes in the plate using a sheet metal punch.
   Reuse the cable entry plate that was removed during base plate installation.

2. Position the cable access plate at the bottom of the frequency converter.

3. Fasten 9 M5x12 screws (T25), attaching the cable access plate to the opening in the base plate adapter.

Lifting the Frequency Converter

LIFTING PRECAUTIONS
The frequency converter is heavy. Failure to follow local safety regulations for lifting heavy weights can cause death, personal injury, or property damage.

• Ensure that the lifting equipment is in proper working condition.
• Check the weight of the frequency converter and verify that the lifting equipment can safely lift the weight.
• Always lift the frequency converter using the eye bolts at the top of the frequency converter.
• Ensure that the angle from the top of the frequency converter to the lifting cable is 65° or greater.
• Test lift the frequency converter approximately 610 mm (24 in) to verify the proper center of gravity lift point. Reposition the lifting point if the frequency converter is not level.
• Never walk under suspended loads.

Example

Wall-mounting the Frequency Converter
FK09c frequency converters can be wall-mounted or pedestal-mounted. To mount the FK09c frequency converter on a wall or mounting panel, use the following steps. See Illustration 8, Illustration 9, and Illustration 10. FK10c frequency converters are pedestal-mounted only. Refer to 2.9 Pedestal-mounting the Frequency Converter.

Procedure

1. Using the dimensions in Illustration 8, prepare the mounting surface.
   Determine proper placement of the frequency converter, considering the operating environment and cable access requirements. Ensure that the air intake and exhaust vents at the back of the frequency converter are not obstructed.

2. Use 4 M10 bolts, 2 in the upper and 2 in the lower mounting holes.

3. Apply the drive slot gasket over the slots at the back lower edge of the frequency converter.

4. Lift the frequency converter and lean it forward slightly, aligning the 2 holes in the lower edge over the 2 lower M10 bolts.

5. Loosely fasten the bolts with 2 M10 nuts.

6. Position the top spacer from the kit behind the mounting flange at the upper edge of the frequency converter.

7. Slowly push the top of the frequency converter back against the mounting surface until the mounting holes line up with the upper 2 M10 bolts.

8. Secure the top of the frequency converter using 2 M10 bolts.
   Torque all fasteners to 19 Nm (170 in-lb).

Pedestal-mounting the Frequency Converter
To mount the FK09c or FK10c frequency converter on a pedestal, use the following steps. See Illustration 11 to Illustration 16.

TIPPING PRECAUTION
If not properly secured, the frequency converter can tip and cause serious injury. After attaching the frequency converter and pedestal to the floor, secure the top of the frequency converter to the wall or mounting panel.
