1.9.2 Installation Procedure

-
The horizontal and vertical decoupling plates are only required for fieldbus connections (see illustrations 2.4 to 2.6).
Procedure
1. Identify the product variant using
2. Ensure the installation environment criteria in
3. Review the wiring schematic (see illustration 2.1). All wiring must comply with local and national regulations related to
cross-section and ambient temperature requirements. Loose connections can cause equipment faults or reduced perform-
ance. Tighten the terminals according to the torque value shown in
4. The drive may be suitable for use on a circuit capable of delivering up to 100 kA short circuit current rating (SCCR) at 480 V.
For fuse, circuit breaker, and switch SCCR ratings, see the VLT
FC 280 Operating Guide.
5. Install the drive following the numbered steps in the Illustrations chapter. Note that certain illustrations pertain to specific
enclosure sizes and are marked as such.
a.
- Attach accessory bag components to the drive.

- For electrical safety ensure the correct grounding of the FC 280 by a certified electrical installer in accordance with
applicable standards and directives.
- Use a dedicated ground wire for input power, motor power, and control wiring.
- Do not ground 1 drive to another in daisy-chain format.
- Keep the motor and ground wire connections as short as possible.
- Follow motor manufacturer wiring requirements.
- Minimum cable cross-section for the ground wires: 10 mm
- Minimum 200 mm (7.87 in) between control cables, motor cables, and mains cables.
- Separately terminated individual ground wires, both complying with the dimension requirements.
- d. Install the control wiring.
- e. Install the motor, mains, and ground wiring.
