Features:
- Changeover role: Routes two labelled ribbon paths through relay-controlled switching points.
- Service references: Enclosure legends identify ribbon, relay, and terminal positions.
- Cabinet format: Mounting flanges support installation within the established control assembly.
The enclosure provides useful visual references for maintaining the original signal route.
Ribbon orientation and relay wiring should be captured before the unit is removed.
Electrical ratings remain tied to the approved Starnet documentation for the installed system.
Apter Power supports 9000-4001 quotations, document requests, and application review for the installed Starnet assembly.

- Path separation: Keep Ribbon 1 and Ribbon 2 tagged throughout removal and refitting.
- Orientation: Photograph keyed connectors and cable exits before releasing them.
- Continuity: Test each route independently when only one path shows a fault.
- Strain relief: Restore cable support so connector load is not carried by the ribbon conductors.
- Command check: Verify the changeover command reaches the intended relay circuit.
- Contact test: Use the approved procedure to inspect switching continuity without bypassing safeguards.
- Terminal map: Retain the numbered conductor schedule with the cabinet drawings.
- Visual inspection: Check terminal security, enclosure damage, contamination, and loose hardware.
- Isolated diagnosis: Separate cable, relay-command, and downstream faults before condemning the unit.
- Recommissioning: Exercise both paths and document the resulting control response.
- Baseline: Keep the final test results with the maintenance history.
- Starnet cabinets: Maintains dual ribbon routing in established Microdrive control assemblies.
- Changeover service: Routes the two labelled ribbon paths through the relay-controlled assembly.
- Cabinet integration: Fits the original flange-mounted position where the established terminal arrangement is retained.
