VLT® HVAC Basic Drive FC 101 Operating Guide

Model: FC 101

Compliance: IEC/UL61800-5-1

Manufacturer: Danfoss

1 Introduction

This operating guide provides necessary information for qualified personnel to install and commission the AC drive. Read and follow the instructions to use the drive safely and professionally.

Do not dispose of equipment containing electrical components together with domestic waste. Collect it separately in accordance with local and currently valid legislation.

2 Safety

Pay particular attention to the safety instructions and general warnings to avoid the risk of death, serious injury, and equipment or property damage.

⚡ HIGH VOLTAGE

AC drives contain high voltage when connected to AC mains input, DC supply, or load sharing.

▶️ UNINTENDED START

The motor may start from control panel, I/O inputs, fieldbus, or VLT® Motion Control Tool MCT 10 at any time, when the drive is connected to the AC mains, DC supply, or load sharing.

⏳ DISCHARGE TIME

The drive contains DC-link capacitors, which can remain charged even when the drive is not powered. High voltage can be present even when the warning indicator lights are off.

Stop the motor, disconnect AC mains and permanent magnet type motors, and remove DC-link supplies, including battery backups, UPS, and DC-link connections to other drives.
Wait for the capacitors to discharge fully and measure it before performing any service or repair work.
The minimum waiting time is 4 minutes for H1-H3 drives, and 15 minutes for H4-H8 drives.

LEAKAGE CURRENT

Leakage currents of the drive exceed 3.5 mA. Make sure that the minimum size of the ground conductor complies with the local safety regulations for high touch current equipment.

? NOTICE: It is not allowed to install FC101 types with UL61800-5-1 in an isolated mains source (IT mains or floating delta) or TT/TN-S mains with a grounded leg (grounded delta).

9 EMC Compatibility and Motor Cable Length

For drives of enclosure size H1-H5:

The drive fulfills EN61800-3 Category C4 for conducted & radiated emissions.
For optimum performance, use unshielded motor cables no longer than 50 m (164 ft) with this drive.
The RFI screw is mounted from the factory and has no impact on EMC performance.

For drives of enclosure size H6-H8:

The drive meets EN61800-3 Category C3 for conducted and radiated emissions; Categories C1 and C2 are achievable with optional filters.

10 Fuses

The recommended fuses in Table 13 Fuses are suitable for use on a circuit capable of delivering 100,000 Arms (symmetrical), 240 V or 480 V depending on the drive voltage rating. With the proper fusing, the drive Short Circuit Current Rating (SCCR) is 100,000 Arms.

Note: (1) RK1 and RK5 fuses are not allowed for H6-H8 drives. (2) H1-H8 drives meet UL 61800-5-1 certification based on the drive being mounted within a larger enclosure (approximately 1.5x the drive) and being centered on the back panel of the larger enclosure. See illustration 8 to 11 for dimensions and allowed vent openings and cable entry points for the tested units. To maintain UL 61800-5-1 certification and to provide the required shielding for vented enclosures, ensure that the spatial relationship between the drive and the vent openings in the larger enclosure is maintained, at a minimum. Larger enclosures can use greater distances to openings. For more information, contact Danfoss support. (3) For drives above 37 kW (50 hp), it is 10 kA for CE compliance. (4) Cabinet is not required for H6 drives if type 1 kit is used. For H6 drives without type 1 kit installed, normal cabinet rules apply.

Diagram Description: Illustrations 8, 9, 10, and 11 show allowed ventilation openings for enclosures H1-H3, H4-H5, H7, and H8 respectively, as tested for UL61800-5-1 compliance. These diagrams provide dimensional layouts for cabinet integration.
