The 6SL3520-0XK02-2AF0 brings the full-featured G120X wall-mounted platform to the 2.2 kW power class, making IP65/66 protection and cabinet-free installation practical for smaller pumps, fans, and compressors. At 11.8 A output and only 134 mm deep, it fits where space is constrained — mechanical mezzanines, rooftop AHU platforms, and treatment skids — without sacrificing the environmental resilience of the larger FSB variants.

How do you size a frequency converter for pump and fan applications?

For centrifugal pumps and fans, the drive is sized by motor nameplate current, not by power. The 6SL3520-0XK02-2AF0 delivers 11.8 A continuously, which comfortably covers 2.2 kW IEC motors at 480 V. The variable-torque overload profile — 200% for 3 seconds, 150% for 57 seconds — provides headroom for startup inrush and momentary hydraulic transients without oversizing the drive. If your motor FLA exceeds 11.8 A or the application requires heavy constant-torque starting, step up to the 3 kW variant.

What makes the wall-mounted G120X suitable for outdoor and wet-location installations?

The sealed IP65/66 enclosure with integrated C2 EMC filter eliminates the need for a ventilated control cabinet. Conduit and cable gland entries maintain the environmental seal, and the -30 to +40°C operating range covers unheated mechanical rooms, rooftop installations, and outdoor skids in most climate zones. The integrated DC link reactor stabilizes operation under all network conditions without external line reactors.

Frequently Asked Questions

Can this 2.2 kW drive run a 3 kW motor at reduced load?

It is not recommended. The drive must be sized to the motor's full-load current rating, not the expected operating load. If the motor draws more than 11.8 A under any operating condition — including startup or overload — the drive will trip or be damaged. Select the drive rating that matches or exceeds the motor nameplate current.

What does the -0AF0 suffix provide over the lower-tier variants?

Within the G120X ordering code structure, the -0AF0 suffix designates the most fully equipped I/O and communication configuration in the product range. It carries the highest I/O point count and the most comprehensive fieldbus interface set. For the exact pin-level I/O and protocol specifications of each suffix variant, refer to the SINAMICS G120X catalog D 31.
