Lenze E84AVSCE5524SX0 8400 StateLine C Inverter 5.5 kW

5.5 kW inverter of the 8400 StateLine C family

The Lenze E84AVSCE5524SX0 is an Inverter Drives 8400 StateLine C frequency inverter for a 5.5 kW four-pole motor, in the built-in (installation) version. It is fed from 3/PE AC 400 V (320 to 440 V) or 500 V (400 to 550 V) and gives 13.0 A rated output current at 45 degrees C. Data on this page comes from Lenze’s Inverter Drives 8400 hardware manual (EDS84ASC552 EN 10.0, covering StateLine C, HighLine C and TopLine C from 0.25 to 45 kW). Lenze presents the 8400 StateLine on its website, but this C-version code should be confirmed for availability and hardware version before ordering.

Technical specifications

Standards and rated conditions

Rated conditions include an output range of 0 to 1000 Hz and IP20 protection with NEMA 250 type 1 contact protection. Certificates named in the manual: CE, EAC (two technical regulations of the Customs Union), UL 508C and, with external mains choke only, CSA 22.2 No. 14.

How the code E84AVSCE5524SX0 breaks down

Position by position: E84 (8400), A (version 1), V (vector), SC (StateLine C), E (installation mounting), 552 (5.5 kW), 4 (4 = 400/500 V three-phase), S (IE33 standard environment), X (without safety system), and finally 0, the standard design.

What the controller offers

Features listed for StateLine C include VFCplus and VFCplus eco V/f control, sensorless vector control, S-ramps, flying restart, brake management and chopper, and 200 percent overload for 3 s. I/O is 5 digital in, 1 digital out, 1 analog in, 1 analog out and a relay, with an HTL encoder input to 10 kHz. CANopen is on board and MCI slots take the fieldbus modules.

Installation and selection notes

Size GG 4 measures 270 x 140 mm in front view. Rated figures hold for 2 and 4 kHz, no choke; 16 kHz gives 8.7 A. Connect a brake resistor of 47 ohm minimum to the internal chopper. A choke cuts the mains current from 18 A to 12.0 A. Order the X400 keypad (EZAEBK1001) and MCI modules separately.

Environmental data: storage 1K3 from minus 25 to plus 60 degrees C, transport 2K3 from minus 25 to plus 70 degrees C and operation 3K3 from minus 10 to plus 55 degrees C. Above the stated temperatures the rated output current falls by 2.5 percent per degree, and above 1000 m altitude by 5 percent per 1000 m, up to 4000 m. Pollution degree 2 applies, and vibration resistance in operation is stated up to 0.7 g. These conditions apply to the 5.5 kW size, rated at 13.0 A.

Operating the 5.5 kW StateLine C in Gulf plant conditions

The operating range of this inverter is minus 10 to plus 55 °C, with full rated current of 13.0 A up to 45 °C and 9.8 A at 55 °C. In an Omani pump house or a rooftop panel that sits in direct summer sun, the air inside an unventilated cabinet can easily exceed the outside temperature, so the realistic rating to plan with is often the derated figure rather than the 45 °C value. A few practical points follow from the manual data:

• Cabinet cooling: at rated current the drive dissipates about 275 W. Size the cabinet fan, filter or air conditioner for this loss plus every other heat source in the enclosure.
• Derating: above the stated temperature limits, output current falls by 2.5 percent per degree; above 1000 m altitude by 5 percent per 1000 m. Most coastal sites in Oman are well below 1000 m, but interior and mountain sites should be checked.
• Dust: the unit is IP20 and rated for pollution degree 2, so it belongs inside a sealed or filtered enclosure. Conductive dust or sand on the heatsink reduces cooling and should be removed during routine maintenance.
• Switching frequency: higher switching frequencies reduce motor noise but lower the available current (8.7 A at 16 kHz). For hot cabinets, staying at 2 or 4 kHz keeps the full rating available.

Typical applications for a 5.5 kW vector inverter

A 5.5 kW four-pole motor is common on conveyors, mixers, circulation and transfer pumps, ventilation fans, packaging machines and material handling equipment. StateLine C combines V/f control (VFCplus and the energy-saving VFCplus eco mode) with sensorless vector control, so the same unit can run a quadratic fan or pump load with reduced energy use or a conveyor that needs good torque at low speed. Flying restart allows the drive to catch a fan that is already spinning, for example after a short supply interruption, and the internal brake chopper with an external resistor of at least 47 ohm handles loads that must decelerate faster than they coast down.

Commissioning and maintenance checklist

1. Check the nameplate against the order code E84AVSCE5524SX0 and confirm the mains voltage (400 V or 500 V range).
2. Install the recommended fuses and, where specified, the mains choke; the choke reduces the input current from 18 A to 12.0 A at 400 V and is required for CSA approval.
3. Use shielded motor cable with the shield bonded at both ends for EMC-compliant installation, and keep control wiring separated from power cables.
4. Enter the motor nameplate data before the first run so that the vector control model matches the motor.
5. Set the ramps, current limit and any brake resistor parameters, then test under load.
6. During periodic maintenance, inspect fans and heatsinks, retighten power terminals and save a copy of the parameter set for fast replacement.

Communication options

CANopen is built in, which suits machines already using CAN-based networks. For plants based on PROFIBUS, PROFINET, EtherCAT or EtherNet/IP, a communication module is fitted in the MCI slot; these modules are ordered separately and should be listed on the request together with the X400 keypad if local parameter access is needed.

What to include in an RFQ

• Complete type code E84AVSCE5524SX0 and the quantity.
• Supply voltage and frequency at site, and whether a mains choke or EMC filter is required.
• Motor nameplate data (power, current, speed, voltage).
• Required fieldbus module and keypad, plus any brake resistor.
• Ambient conditions inside the panel and the existing unit’s hardware version if this is a replacement.

Documents and quotation

The attached Lenze hardware manual carries the complete rating, dimension, fuse and accessory tables. See AC Drives for related inverters. A quotation needs the complete code, mains voltage, motor nameplate and fieldbus; the variant should be verified against the nameplate before ordering.
