This guide provides essential steps for installing the Danfoss iC7-Automation Frequency Converters. Always refer to the full documentation for detailed safety and application information.
- Safety: Read the safety guide (136R0243) before starting.
- Tools: Ensure you have a lifting aid, tape measure, 10 mm socket, Torx/slotted screwdrivers, wire crimper, and sheet metal punch.
- Mounting: Mount on a solid, non-combustible surface with proper cooling clearance.
- Wiring: Use shielded cables for motor, brake, DC, and control wiring.
- STO: The Safe Torque Off function is active by default; use jumpers to disable if not using a safety device.
Product Label
The product label is located on the top of the drive. It contains the model code, serial number, power rating, and compliance information. Use a Datamatrix ECC 200 compatible reader to scan the 2D code for full product details.
Installation Procedure
- Identify the frame designation.
- Verify the operating environment (Indoor, pollution degree 2, overvoltage category 3).
- Review wiring diagrams and fuse specifications.
- Install accessory bag components.
- Mount the drive on a solid surface.
- Drill cable openings and install glands (for FK06-FK08).
- Install control, motor, mains, and PE ground wiring.
- Secure the cover.
- Perform initial setup and fieldbus configuration.
Functional Safety (Safe Torque Off)
The STO function is active by default. To disable it, install jumper wires to terminals X31 and X32. To use it, wire a safety device to the safe I/O terminal blocks. A commissioning test is required after installation.
EMC-compliant Installation
For EMC-compliant installation, use shielded cables for motor output, brake, DC, and control wiring. Connect the shield to the enclosures at both ends. If shield connection points have a voltage potential difference, connect a low impedance equalizing wire parallel to the shielded cable. Keep motor, brake, and DC cables as short as possible and maintain a minimum 200 mm separation between mains input, motor cables, and control cables.

Practical help
Common problems
Loose electrical connections
Tighten terminals according to the proper torque value shown in the installation steps.
Electromagnetic interference
Use shielded cables, ensure proper EMC plate contact, and maintain 200 mm separation between cable types.
Motor will not turn (STO active)
Install jumper wires to terminals X31 and X32 to disable the STO function if no safety device is used.
Before use
- Verify shipment contents against order confirmation.
- Ensure installation surface is solid and non-combustible.
- Check ambient temperature (max 45°C average, 50°C for 1 hour).
- Verify altitude is below 1000 m.
- Ensure proper cooling clearance above and below the drive.
Images and diagrams
- Wiring diagram (Illustration 1, page 27) shows power and control connections.
- Mounting dimensions (Illustration 5, page 39) provide spacing requirements.
- Cable entry (Illustration 6, page 40) details gland installation.
Model compatibility
- Suitable for asynchronous, synchronous, and permanent magnet motors.
- Requires specific copper wire temperature ratings (70°C or 90°C depending on frame).
