Danfoss 135X8653 at a glance
The Danfoss 135X8653 is a 2.2 kW / 3.0 HP VLT HVAC Drive FC 102 for 3 × 380–480 V AC supplies, made for the fans, pumps and compressors in building services. It is a frame A5, IP55 / UL Type 12 unit, built for wall mounting in plant rooms without a separate enclosure.
This configuration has RFI class A1/B (C1), no brake chopper, a graphical LCP 102 control panel, and a PROFIBUS DP MCA 101 fieldbus card. The full type code is decoded alongside the FAQs.
Sizing and installation
- Enclosure: IP55 / UL Type 12 — built for wall mounting in plant rooms without a separate enclosure.
- EMC: RFI class A1/B (C1). Check the permitted screened motor cable length in the Danfoss FC 102 Design Guide.
FC 102 features for HVAC
- Built-in RS-485 protocols: Danfoss FC, Modbus RTU, BACnet MS/TP, Metasys N2 and FLN Apogee — connects to most building management systems without an option card.
- Fire Mode keeps the drive running during an emergency, for example to keep smoke-extract fans turning.
- Automatic Energy Optimisation (AEO) cuts motor losses at part load — Danfoss quotes a further 5–15% saving.
- Pump and fan functions: sleep mode, dry-pump, end-of-curve and broken-belt detection, plus a built-in cascade controller for pump sets.
- Built-in DC coils limit mains harmonics (EN 61000-3-12).
- Smart Logic Controller for simple sequencing without a PLC.
Where the energy saving comes from
Centrifugal fans and pumps follow the affinity laws: absorbed power falls with the cube of speed. Running at 80% speed needs roughly half the power of full speed (0.8³ ≈ 0.51, before motor and drive losses) — which is why speed control pays back faster on fans and pumps than almost any other load.
