Data center engineering in France.

Paris is a top-five European interconnection market and Marseille is a major subsea landing point for routes into the Mediterranean, Africa and Asia. French operators expect French-language documentation and are strict about habilitation électrique.

Local delivery context

The details that matter on site.

Standards & evidence

  • NF EN 50173 and NF EN 50174 for cabling
  • NF EN 50600 for facility design and operations
  • NF C 15-100 for low-voltage electrical installation

Regulatory context

  • EU GDPR supervised by the CNIL
  • HDS certification requirements where health data is hosted
  • ANSSI guidance and SecNumCloud where the tenant is public sector
  • NIS2 through the French implementation

Safety & site access

  • Habilitation électrique (B1V, B2V, BR, BC) matched to the work
  • Plan de prévention for contractor intervention on an occupied site

The customer’s site rules and contract take precedence. Standards, access requirements and response times are confirmed for your specific facility during scoping.

Access & working windows

Plan around the facility.

Plan de prévention must be agreed before intervention on occupied sites. Photo ID and a signed engagement de confidentialité are standard.

Paris and Marseille hubs give eight-hour mobilisation. French sites commonly close works in August — plan major projects around it.

Working languages: French (native), English.

Power & testing

Verify, then hand over.

230/400 V, 50 Hz. IEC 60320 C13 and C19; Type E on auxiliary circuits.

IEC 61935-1 certification with French-language reporting. Fibre tested to IEC 61280-4-2 with OTDR traces per link.

Local questions

Before you build in France.

Do your engineers hold habilitation électrique?

Yes, matched to the task — B1V or B2V for execution, BR for intervention, BC for consignation. Certificates are supplied before mobilisation.

Is the documentation in French?

Yes. Test results, handover notes and the procès-verbal de réception are produced in French, with an English version on request.

Can you work on HDS-scoped infrastructure?

We work to the handling and traceability controls an HDS-certified host requires, and we can sign the confidentiality and processing agreements. We do not hold HDS certification ourselves and will not imply it.
