Lenze E84AVSCE2224SB0 8400 StateLine C Inverter 2.2 kW

2.2 kW StateLine C inverter, Safe Torque Off version

As a StateLine C inverter, the Lenze E84AVSCE2224SB0 controls a 2.2 kW motor from 3/PE AC 400 V (320 to 440 V) or 500 V (400 to 550 V). Its GG 3 housing is 270 mm high and 70 mm wide. The numbers come from the 8400 hardware manual EDS84ASC552 EN 10.0 published by Lenze for StateLine C, HighLine C and TopLine C devices of 0.25 to 45 kW; please confirm availability and the hardware version of this exact code before ordering.

Technical specifications

General data and approvals

The output frequency range is 0 to 1000 Hz. The enclosure is IP20 with NEMA 250 type 1 protection against accidental contact. Approvals printed in the manual are CE, EAC (TR CU 004/2011 and TR CU 020/2011), UL 508C and CSA 22.2 No. 14; the CSA approval applies only when an external mains choke is used.

Decoding E84AVSCE2224SB0

Following the manual’s product key: E84 is the 8400 range, A the first version, V the vector-controlled type, SC the StateLine C, E the installation mounting, 222 the power (22 x 10^2 W = 2.2 kW), 4 the voltage class (4 = 400/500 V three-phase), S the standard industrial environment, then B (integrated safety system Safe Torque Off) and 0, the standard design.

What the B in the code adds

With the B version, STO is built into the drive: the manual describes a direct torqueless state per EN 60204-1 and lists SIL 3 and PL e / Category 4 for the safety functions. Installation and commissioning belong in qualified hands, and the unit is 219 mm deep.

Installation and selection notes

The GG 3 housing is 270 mm high and 70 mm wide. Output current is given for 2 and 4 kHz without a mains choke, with 3.7 A at 16 kHz. The internal brake chopper switches at its adjustable threshold and needs a resistor of at least 150 ohm. A mains choke reduces the mains current from 7.3 A to 5.1 A. The plug-in keypad X400 (EZAEBK1001) and the MCI fieldbus modules are separate accessories.

Wiring limits: the manual gives maximum shielded motor cable lengths that depend on the switching frequency, for example 50 m at 4 and 8 kHz for the smaller sizes, and it requires motor cables with limited capacitance per unit length. DC-bus operation is possible with direct connection on devices with a 400 V mains connection. Short-circuit and earth-fault protection of the motor connection is limited, meaning an internal protective device responds and inhibits the controller until an error acknowledgement is given.

Selection checks for the E84AVSCE2224SB0

Start from the motor nameplate rather than the kilowatt figure alone. Compare the motor rated current with the continuous current values in the table, and remember that the available current falls as the cabinet temperature rises from 45 to 55 °C and as the switching frequency is raised. If the application needs quiet operation at a high switching frequency, check the reduced current figure at 16 kHz against the motor before settling on this size.

Then confirm the safety concept. The B in the type code means Safe Torque Off is integrated, so the machine’s risk assessment, the safety relay or safety controller and the wiring of the STO inputs all need to be agreed with whoever is responsible for functional safety on the machine. Decide also whether a mains choke, a brake resistor, the X400 keypad or an MCI fieldbus module are needed, since these are separate items.

Panel design for Gulf summer temperatures

With 135 W of heat loss from one unit, a few of these inverters side by side add a noticeable heat load to a cabinet. In Oman and the wider GCC, panels in unconditioned plant rooms, pump stations and outdoor skids regularly see internal temperatures well above what an office-based design would assume. Size cabinet cooling for the hottest months, and treat the 55 °C current figure as a warning that output capacity drops as heat builds up, not as a target operating point.

Fine desert dust is the second concern. Because the enclosure is IP20, the cabinet must keep sand out: use filter mats on air inlets, seal unused cable entries and check door gaskets during routine visits. At coastal sites humid air and salt can lead to condensation and corrosion on terminals, so avoid sudden cooling of the cabinet and consider anti-condensation heaters where panels are switched off overnight.

Wiring practice

Use shielded motor cable of the type the manual calls for, bond the shield at both ends with full-surface contact, and keep motor, mains and control cables in separate routes. Stay within the motor cable lengths the manual allows for your switching frequency, and keep STO wiring clearly identified so that it is not altered during later modifications.

Commissioning and periodic maintenance

Before enabling the drive, check mains voltage, fusing, earthing and the brake resistor value against the manual. Enter the motor data, run the motor with the machine in a safe state, and verify direction and acceleration. Test the Safe Torque Off function as part of commissioning and record the result in the machine’s safety documentation; repeat the test at the intervals your safety assessment specifies.

In service, clean dust from heatsinks and cabinet filters, check terminal tightness and look for discoloured insulation that suggests overheating. Save a copy of the parameter set after commissioning and after any change, so a replacement inverter can be restored quickly if needed.
