Switzerland / Water treatment / utilities
Project definition
An illustrative engineering pack for MCC-to-PLC and field instrumentation interfaces in a water treatment retrofit.
Illustrative subcontract scope
- Cable and terminal interfaces
- I/O-to-field device reconciliation
- Revision and vendor comments register
- Electrical scope boundary matrix
Client inputs
- Existing facility drawings
- MCC control interfaces
- Field device register
- Owner technical standards
Standards to check — not conformity claims
- SN 411000:2025 (NIN) for LV installations
- Relevant IEC/EN equipment standards
- Site/client-specific technical rules
Applicability note: NIN is an installation standard; it does not automatically regulate every PLC cabinet subassembly. Swiss installation approval requires qualified local parties.
