This is the VLT 3000 frequency converter product manual, which introduces the features and characteristics of the product, such as electrical safety, installation, connection, operation, maintenance and control.
This manual covers safety rules, quick setup, mechanical and electrical installation, and detailed operational instructions for all VLT® 3000 Series frequency converters. It explains how the device identifies its size and voltage on start‑up and provides guidance for parameter programming, motor adaptation, and special conditions such as extreme temperatures and EMC requirements.
Additional sections describe fault diagnostics, service procedures, accessory connections, and an index for fast reference. The document is intended for both first‑time users and experienced technicians working with Danfoss VLT® converters.
| Output voltage range | 10‑100% of supply voltage |
|---|---|
| Output frequency range | 0.5‑120 Hz / 0.5‑500 Hz |
| Mains supply (low voltage) | 3 × 200/220/230 V AC, 50/60 Hz |
| Mains supply (medium voltage) | 3 × 380/400/415 V AC, 50/60 Hz |
| Mains supply (high voltage) | 3 × 440/460/500 V AC, 50/60 Hz |
For VLT® 3002‑3052 wait 4 minutes; for VLT® 3060‑3250 wait 14 minutes.
When the supply voltage is connected, the VLT automatically enters DISPLAY MODE and shows its size and voltage on the display.
After the supply voltage is connected, the VLT is automatically in DISPLAY MODE.
