Description

System Overview

The 3500/05-01-03-05-00-01 is a full-capacity chassis designed for the Bently Nevada 3500 machinery protection architecture. It functions as the central structural platform that houses all monitoring, relay, communication, and power modules while enabling system-wide communication and regulated power distribution through an integrated backplane.

This configuration is specifically engineered for installations requiring front-side wiring access, making it suitable for wall-mounted or cabinet-integrated protection systems.

Configuration Definition

This rack variant is defined by the following configuration structure:

• Full-size chassis with 14 module positions

• Bulkhead-mount installation format with front-access wiring design

• Standard non-barrier backplane architecture

• No internal isolation barriers included

• Standard EIA finish and mechanical specification

Mechanical Construction & Access Design

• Rack format: 19-inch EIA full-size chassis

• Mounting style: Bulkhead installation with front-access wiring layout

• Frame material: Industrial-grade aluminum alloy

• Nominal dimensions:

• Height: ~266 mm

• Width: 483 mm

• Depth: ~305 mm

• Serviceability: All field wiring connections accessible from the front panel

This design reduces rear clearance requirements and simplifies cabinet integration in constrained installations.

Module Layout & Slot Allocation

The internal slot architecture supports structured system configuration:
