Lenze E84DGDVB75242PS 8400 motec Inverter 7.5kW IP54

Lenze 8400 motec Inverter E84DGDVB75242PS

Product Introduction

The Lenze 8400 motec series brings drives directly to the motor. Model E84DGDVB75242PS is a 7.5 kW inverter. It connects to a 3-phase 400 V mains supply. Voltage range spans 340 to 528 V AC at 45 to 65 Hz.

Rated output current reaches 16.5 A. The housing provides IP54 protection. Therefore, this drive suits harsh environments like conveyor lines, cranes, and outdoor machinery.

Technical Specifications

Power and performance are robust. Rated power equals 7.5 kW. Overload capacity reaches 200% for 3 seconds and 150% for 60 seconds. Maximum output frequency runs from 0 to 599 Hz.

Switching frequencies are selectable: 4, 8, or 16 kHz. The rated output current applies at 45°C with 4 kHz. At 8 or 16 kHz, the ambient temperature must stay at or below 40°C.

Power loss measures 0.2 kW. Mass of the unit is 5.3 kg. For shipping, gross weight equals 6.1 kg.

Environmental and Protection Data

The E84DGDVB75242PS offers multiple protection levels.

• IP65 for the basic drive unit

• IP64 for the service switch with protective function

• IP54 for the service switch alone

• IP54 for the service switch with control elements

Additionally, NEMA ratings apply. Type 1 provides touch protection. For wall mounting units from 0.37 to 3 kW, Type 12 is available. This Lenze 8400 motec unit specifically carries IP54.

Ambient temperature max is 55°C. Above 45°C, derating applies at 2.5% per degree Celsius.

Power System and RCD Compatibility

The Lenze 8400 motec inverter works on TN power systems. Voltage to earth must not exceed 300 V. Mains switching is allowed three times per minute.

For residual current devices (RCDs), note these rules:

• Use 30 mA, Type B when motor mounting or wall mounting with Lenze system cable below 3 m

• Use 300 mA, Type B for wall mounting with Lenze system cable longer than 3 m, or for motor mounting at 4.0 to 7.5 kW with 4 kHz switching frequency

Cable Length Limits

Maximum shielded motor cable length is 20 m. For EMC Category C2, follow these limits with Lenze system cables:

• Below 20 m when wall mounting and switching frequency ≤ 4 kHz

• Below 10 m when wall mounting and switching frequency ≤ 8 kHz

Approvals and Conformities

The E84DGDVB75242PS meets several standards.

• CE: 2014/35/EU (LVD) and 2014/30/EU (EMC)

• EAC: TP TC 004/2011 and TP TC 020/2011

• RoHS 2: 2011/65/EU

• UL: UL 508C

• CSA: CSA 22.2 No. 274

Therefore, you can install this Lenze 8400 motec drive in North America and the Eurasian Economic Union.

Installation Guidelines

First, mount the E84DGDVB75242PS directly on a motor or on a wall. Use the integrated service switch for local disconnect. Second, connect the 400 V mains to the power terminals. Third, keep the shielded motor cable within 20 m.

Furthermore, ensure the ambient temperature stays below 45°C for full rated current. Use Lenze system cables to maintain EMC compliance. Finally, select the correct RCD type based on your cable length.

Frequently Asked Questions (FAQ)

1. Can I run the E84DGDVB75242PS at 16 kHz switching frequency?
Yes, but derating applies. At 16 kHz, the maximum ambient temperature drops to 40°C for full output current. Otherwise, reduce the load by 2.5% per degree Celsius above 40°C.

2. Is this Lenze 8400 motec inverter suitable for outdoor use?
Yes, thanks to IP54 rating. However, avoid direct water jets. For heavy rain or washdown, choose the IP65 version.

3. What happens if I exceed 20 m motor cable length?
The E84DGDVB75242PS may cause higher EMI emission. Reflected wave voltages can also damage motor insulation. Use an output filter or shorten the cable.

4. Do I need an external braking resistor?
It depends on your application. For high inertia loads or frequent deceleration, add a braking resistor. The Lenze 8400 motec has an internal braking chopper.

5. How do I change the operating mode from 4 kHz to 8 kHz?
Adjust parameter C0005. Then recalculate the derating. Remember to check the motor cable length, because EMC limits become stricter at higher frequencies.
