Product Description:
The 131U7904 is an installation box variant in the VLT FCD 302 Decentral Drives line from Danfoss. It serves as the mounting and connection point for a decentralized frequency converter. This arrangement lets the drive electronics sit close to the load, which helps shorten cable runs in industrial automation cells. The box is intended for decentralized layouts where motor connections and incoming power are routed at the machine instead of back to a central control cabinet. The product belongs to the VLT Decentral Drive FCD group and carries the internal series code 302.
This model accepts a three-phase input of 380-480 VAC, which matches common plant mains supplies used with industrial drives. It uses a standard white IP66/NEMA 4X enclosure that protects internal parts against dust, washdown spray, and corrosion in demanding machine areas. An integral RFI Class A1/C2 filter reduces conducted emissions on commercial power systems and supports use without a separate line filter. Cable entry is provided through metric threads, and the box includes a display connector for a detachable keypad used for setup and diagnostics. There is no fieldbus plug, mains plug, motor plug, or sensor plug, so those connections are made directly inside the gland plate.
The unit is configured with no fieldbus option, and it is also supplied without B or D options and without a switch option. The hardware is identified as a small standalone installation box, which indicates that it operates independently rather than as an add-on to a prewired motor. Its power designation is installation box only, so the actual inverter and motor are specified separately in the machine bill of materials. The box also comes without a brake, brackets, or switchgear, leaving mounting hardware and external cabling choices to the machine design. All electrical noise suppression is handled by the built-in filter.
