Rexroth HMV01.1R-W0018-A-07-FNN1 | IP20 Supply Unit

Unboxing & Physical Snapshot

• Model & Brand: Bosch Rexroth Indramat HMV01.1R-W0018-A-07-FNN1
• Rexroth reference: R911329716.
• Equipment type: HMV IndraDrive M regenerative supply unit.
• Physical dimensions: Exact W × H × D should be taken from the OEM mechanical drawing before cabinet layout or freight booking. Public listings reviewed do not provide sufficiently reliable dimensional data.
• Estimated shipping weight: Do not use an unverified catalog figure. One reseller lists 1.5 kg, but that figure is inconsistent with the physical nature of an 18 kW power unit and should not be used for freight documentation without weighing the actual packed assembly.
• What’s in the box: HMV01.1R-W0018-A-07-FNN1 supply unit; original mounting hardware and documentation only if included with the specific inventory lot.
• Receiving inspection: Photograph the rating plate, type code, R911 reference, serial/date code, connectors, cooling assembly, and enclosure before unpacking.

Product Introduction

Architecture hook: This unit belongs to the Rexroth IndraDrive M HMV supply architecture, where the power supply establishes the DC bus used by connected drive controllers. The specified variant is a regenerative HMV supply unit, rated for an approximately 700 V DC bus and 18 kW output power.

Physical installation therefore deserves more scrutiny than the model number alone suggests. The HMV01.1R uses internal air cooling with an integrated blower and carries an IP20 protection rating; cabinet airflow, grounding, and separation from contamination sources are part of the installation basis.

Core Technical Specifications

Rexroth HMV01.1R-W0018-A-07-FNN1

The 18 kW rating and 700 V DC bus are the critical electrical identifiers for asset matching.

? Global Compliance & Industry Certifications

For this class of industrial drive power equipment, the compliance file should be checked for the exact product revision rather than assuming certification from the Rexroth brand.

• CE Mark: Verify the actual rating plate and applicable declaration of conformity.
• UL/cUL: Verify whether the exact HMV configuration carries North American certification and under what installation conditions.
• ATEX / IECEx: Do not treat the HMV01.1R as hazardous-area certified without explicit OEM documentation for the exact variant.
• Marine approvals: DNV or other marine classification should only be claimed when the exact type code and installation configuration are covered.
• EMC: Available technical listings identify compliance with EN 61800-3.

The grounding requirement is significant because power-conversion equipment can produce leakage current; inadequate protective grounding can create an electrical safety hazard and compromise EMC performance.

Verify specific lot certifications with OEM.

? Long-Term Storage & Asset Preservation Guide

• Preserve the blower and heatsink assembly. Keep the unit sealed against dust and moisture. Do not store it where airborne oil, metal particles, or high humidity can contaminate the blower path and heatsink fins.
• Use ESD-controlled packaging. Protect exposed electrical interfaces and connectors with the original packaging or suitable ESD-safe protection; avoid placing the unit directly on conductive or abrasive shelving.
• Control condensation. Maintain a dry warehouse environment, preferably below 60% RH, and allow the power unit to reach room temperature before opening sealed packaging after cold transport.

For a long-stored power converter, do not simply energize it after years on the shelf and immediately connect the production DC bus. Inspect the electrolytic-capacitor condition, cooling path, connectors, insulation condition, and date code first; any manufacturer-specific reforming procedure takes precedence.

Physical Installation Prerequisites

• Mount the HMV supply according to the Rexroth mechanical installation documentation and specified cabinet orientation.
• Provide sufficient clearance around the integrated blower and heatsink for unobstructed airflow. Do not substitute a generic 50 mm clearance requirement for the OEM drawing.
• Keep cable bundles and cabinet partitions away from the blower intake and exhaust path.
• Establish the specified protective grounding connection before energization.
• Verify DC-bus wiring, conductor sizing, protective devices, and regenerative power configuration against the complete IndraDrive system design.
• Because the unit operates around 700 V DC, apply the site’s high-voltage isolation, lockout/tagout, discharge-time, and verification procedures before physical handling.

Buyer’s FAQ

Q: What HS Tariff Code should be declared for R911329716?
A: Do not classify it solely as a generic “servo drive.” This is an HMV regenerative supply unit, so the customs classification should be determined from its confirmed electrical function, construction, and applicable national tariff schedule. Retain the technical datasheet supporting the classification.

Q: What should I use for Country of Origin?
A: Use the actual manufacturing origin supported by the product label, OEM documentation, or supplier-origin declaration. Do not infer COO from the Bosch Rexroth corporate headquarters or the seller’s shipping location.

Q: Is shipping insurance worthwhile for this unit?
A: Yes, particularly for an 18 kW power supply with a high replacement cost or long procurement lead time. Record the serial number and pre-shipment condition, then use impact-resistant packaging that protects the blower, heatsink, connectors, and enclosure from mechanical shock.

Q: Does R911329716 arrive with the latest firmware?
A: Firmware currency should never be assumed from the part number. This is a hardware type code; record the actual firmware/configuration information from the unit and compare it against the approved IndraDrive system baseline before commissioning.
