560 kW HVAC drive — FSJ frame, IP20, integrated BACnet
The 6SL3220-3YE66-0CB0: The SINAMICS G120X is Siemens' infrastructure converter family purpose-built for HVAC, water, and wastewater applications. This FSJ-frame unit delivers 560 kW rated power with a 135% overload for 3 seconds, 110% for 60 seconds, and 100% for 240 seconds — a duty cycle matched to pump and fan load profiles where short-duration starting torque is the constraint, not continuous peak current. Input range is 3AC 380-480 V +10%/-20% at 47-63 Hz, covering the common global low-voltage industrial supply. The built-in RFI suppression filter meets Category C3 for second-environment (industrial) installations — no external filter needed for most plant-floor runs, though a C2 filter may be required at the point of common coupling depending on local EMC regulations. The drive ships with an Intelligent Operator Panel (IOP) for local commissioning and diagnostics. No IO expansion module is included — the base unit carries MODBUS RTU, BACnet MS/TP, and USS on the integrated fieldbus port, which covers the majority of BMS and SCADA integration without add-on cards.
Panel fit and physical integration
Packaging dimensions are 1,200 x 1,857 x 800 mm — this is a large-frame drive requiring a floor-standing enclosure or dedicated drive cabinet. The IP20 / UL open-type degree of protection means the drive is not sealed against dust ingress; it must be installed in a clean, ventilated enclosure with adequate clearance for the heatsink airflow. Ambient temperature rating is 0 to +45 °C without derating; above that, output current must be reduced per the derating curve in the operating instructions. Product class C means this unit is manufactured to order and cannot be returned or re-used — confirm the BOM position and enclosure cut-out before committing. The FSJ frame uses a standard Siemens mounting pattern; gland-plate planning should account for the 3-phase input, motor output, and fieldbus cable entries at the bottom of the chassis.
Compliance and regulatory documentation
RoHS compliance is confirmed since March 2020. REACH Article 33 duty to inform applies — the drive contains lead (CAS 7439-92-1) above 0.1% w/w in certain components, which must be communicated down the supply chain. Export control classification is AL: N / ECCN: EAR99H — no special license required for most destinations, but the H suffix indicates a national-security controlled item under US regulations; verify end-use and end-user before cross-border shipment.
