Product Description
🏗️ Compact Infrastructure for Mission-Critical Machinery Protection
The Bently Nevada 3500/05 Mini Rack (Model 3500/05-02-04-00-00-01) delivers enterprise-grade monitoring infrastructure in a space-efficient 12-inch form factor. Engineered for installations where panel real estate is limited yet monitoring requirements remain uncompromising, this 7-slot mini rack provides the backbone for complete vibration, temperature, and process monitoring systems.
💡 Why Choose the Mini Rack Configuration?
✓ Space Optimization: 50% smaller footprint than full-size racks—ideal for skid-mounted packages, offshore platforms, and retrofit installations where panel space is constrained.
✓ Cost Efficiency: Right-sized for single-train monitoring (1-3 machines)—avoid over-provisioning while maintaining expansion capability for future growth.
✓ Panel Integration: Flush-mount design integrates seamlessly into control cabinets and MCC panels—no external rack mounting hardware required.
✓ Modular Scalability: Deploy multiple mini racks for distributed monitoring architectures—each rack dedicated to a specific process unit or machine train.

🔧 Installation & Integration Guidelines
Panel Preparation Requirements:
- Cutout Dimensions: Create 292 mm × 254 mm (11.5" × 10.0") opening in panel—verify clearances before cutting
- Panel Thickness: Suitable for 1.5-3.0 mm (16-20 gauge) steel or aluminum panels
- Rear Clearance: Ensure minimum 300 mm (12") depth behind panel for module insertion and cable routing
- Ventilation: Provide 100 mm (4") clearance above and below rack for convection cooling—no forced air required
- Grounding: Connect rack chassis to panel ground using M6 grounding stud on rear panel
Module Installation Sequence:
- Power Supplies First: Install 3500/15 power modules in leftmost slots (positions 1-2)—these must be installed before other modules
- TDI Module: If using transient data capture, install 3500/22M immediately to the right of power supplies
- Monitor Modules: Populate remaining slots with monitoring modules in any order—backplane auto-detects module types
- I/O Modules: Attach external I/O modules to rear of each monitor—verify correct I/O type for application
- Power-Up Sequence: Apply power—all modules should illuminate OK LEDs within 30 seconds
Cable Management Best Practices:
- Route field wiring through bottom cable entry—use cable glands rated for panel environment
- Separate power cables from signal cables—maintain 150 mm (6") minimum spacing
- Label all cables at both ends with module slot number and channel designation
- Use strain relief on all external connections to prevent connector damage from cable pull
⚠️ Critical Design Considerations
| Consideration | Requirement |
|---|---|
| Power Budget | Maximum 7 full-height modules @ ~5W each = 35W total—single 3500/15 power supply (75W capacity) is sufficient |
| Ambient Temperature | -30°C to +65°C operating range—derate above 55°C or provide forced cooling |
| Humidity Limits | 95% RH non-condensing—use panel heaters in high-humidity environments to prevent condensation |
| Vibration Exposure | Rack is rated for 0.5g continuous vibration—avoid mounting directly on reciprocating equipment |
| Expansion Limitations | Cannot be expanded beyond 7 slots—plan for future growth by deploying full-size rack (14 slots) if expansion likely |

🔄 Upgrade & Migration Paths
From Legacy 3300 Systems: The 3500/05 mini rack provides a compact migration path from 3300 XL monitoring systems. Existing proximity probes, extension cables, and transducers are fully compatible—only monitor modules and rack infrastructure require replacement.
To Full-Size Rack: If monitoring requirements grow beyond 7 slots, modules can be relocated to a 3500/05-01 full-size rack (14 slots) without reconfiguration—all settings and alarm parameters transfer via configuration software.
Distributed Architecture: Deploy multiple mini racks for geographically distributed monitoring—each rack operates independently with local alarm outputs, or network via 3500/92 gateways for centralized SCADA integration.
