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 per the corresponding service guide.
  • Use the standard fastener torque values from the service guide, unless the torque value is specified in these instructions.

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.

Installation Overview
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.

Installing the Back Vent Gasket
To install the back vent gasket, use the following steps. See Illustration 3.

Procedure

  1. Peel the paper from the self-adhesive back vent gasket.
  2. Attach the back vent gasket around the upper opening in the back of the frequency converter.

Installing the Base Plate
Use the following steps to attach the base plate and cable entry plate to the frequency converter. See Illustration 4 and Illustration 5.

Procedure

  1. Unfasten 8 M5x12 screws (T25) from the existing cable entry plate (gland plate), and remove the plate from the bottom of the frequency converter.
    Keep the screws for the installation of the new cable entry plate.

  2. Attach the base plate:

    • a. Adhere the base plate gasket to the upper side of the base plate.
    • b. Position the base plate at the bottom of the frequency converter.
    • c. Secure the base plate using 6 M5x12 screws (T25) from the kit.
  3. Install the cable entry plate:

    • a. Cut holes in the cable entry plate for the glands (not provided).
    • b. Adhere the cable entry gasket to the upper surface of the cable entry plate.
    • c. Position the cable entry plate over the opening in the base plate below the mains and motor terminals.
    • d. Secure the cable entry plate to the base plate using 8 M5x12 screws (T25) screws removed in step 1.

Mounting the Frequency Converter
To mount the frequency converter on a wall or mounting panel, use the following steps. The kit is not compatible with pedestal mounting.

Procedure

  1. Using the dimensions in Illustration 6 for FK09a/FB09a or Illustration 7 for FK10a/FB10a, 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. Adhere the 2 seal plate gaskets to the seal plates, 1 per plate.

  3. Place 2 seal plates inside the back channel and over the 2 mounting slots in the lower edge of the frequency converter enclosure.

  4. Lift the frequency converter and fasten 4 M10x30 mm screws, 2 in the upper mounting holes and 2 in the lower mounting holes.
    The 2 seal plates function as washers for the lower mounting screws. Torque all fasteners to 19 Nm (170 in-lb).

Assembling the Lower Duct
To assemble the lower duct, use the following steps. See Illustration 10 .

Procedure

  1. Peel the paper from the left and the right side gaskets, and press to attach the gaskets to the duct frame.
    Align the holes in the side gaskets with the holes in the back opening of the duct frame.

  2. Place the back grill over the left and right side gaskets.
    The threaded studs in the grill go through the middle holes in the gasket and into the duct frame.

  3. Secure the back grill to the duct frame using 1 M5 nut on each stud.
    Torque to 2.3 Nm (20 in-lb).

  4. Affix the grill gasket to the outer side of the back grill.

  5. Affix the bottom cover gasket to the bottom cover plate.

  6. Secure the bottom cover plate to the underside of the duct frame with 12 M5 nuts (for FK09a/FB09a) or 14 M5 nuts (for FK10a/FB10a).
    Torque to 2.3 Nm (20 in-lb).

  7. Place the duct front gasket on the front of the duct frame, making sure the holes in the frame and gasket align.

  8. Affix the top gasket to the top of the duct frame.
    Wait to attach the front duct cover until the assembled duct is attached to the frequency converter.
