Description

Product Overview

The 3500/05-02-05-00-00-01 is a compact configuration within the Bently Nevada 3500 machinery protection platform, engineered for installations where space efficiency and front-access wiring are required. It combines a reduced 7-slot chassis with a bulkhead mounting structure, enabling direct cabinet or wall integration while maintaining full system compatibility.

This rack provides the structural foundation, power routing, and backplane communication required for continuous machinery monitoring and protection in API 670–compliant environments.

Configuration Definition

This model is defined by the following system layout:

• Mini rack frame with 7 module positions

• Bulkhead mounting design with front-side wiring access

• Standard non-barrier backplane architecture

• No internal isolation barriers included

• Standard EIA mechanical finish specification

Mechanical Construction

• Rack type: Mini-size 3500 chassis

• Mounting method: Bulkhead installation (front-access wiring layout)

• Frame material: Industrial-grade aluminum alloy

• Approximate dimensions:

• Height: ~178 mm (7 in)

• Width: 305 mm (12 in)
