Description

System Overview

The 3500/05-02-04-00-00-00 is a compact rack assembly within the Bently Nevada 3500 protection platform. It is engineered for installations where cabinet space is limited but full machinery protection functionality is still required. The unit integrates mechanical housing, electrical backplane routing, and modular power distribution in a reduced 7-slot configuration.

This mini rack maintains full compatibility with the 3500 system architecture while reducing footprint compared to standard 14-slot chassis designs.

Configuration Definition

This model is defined by the following structure:

• Mini rack chassis with 7 module positions

• 19-inch rack-mount installation format

• Standard non-barrier backplane architecture

• No internal isolation barriers included

• Standard finish configuration

The design supports compact system integration without compromising signal integrity or system reliability.

Mechanical Construction

• Rack type: Mini-size 3500 chassis

• Mounting style: Rack-mount (EIA 19-inch rails)

• Construction material: Industrial-grade aluminum alloy

• Approximate dimensions:

• Height: ~178 mm (7 in)

• Width: 305 mm (12 in)

• Depth: ~305 mm (12 in)

• Service access: Rear wiring access for rack-mounted cabinet installations

The reduced frame size is optimized for skid systems and compact enclosures.
