Understanding the FuP/EuP role: why not everyone in an EV workshop needs FHV qualification

When Chinese EV manufacturers establish operations in Europe, a critical question often goes overlooked: does every technician on my workshop floor need an FHV (skilled person for high-voltage systems) qualification? The answer is no.

DGUV Information 209-093 — the German standard for high-voltage work on electric vehicles — specifically defines the FuP/EuP role (Fachkundig unterwiesene Person, or electrically instructed person, at qualification level Stufe 1). This role meets legal requirements whilst significantly reducing training costs and accelerating workforce deployment timelines.

This article examines the FuP role across three dimensions: regulatory foundation, task authority and limitations, and supervision mechanisms.

Why the FuP role exists: understanding the qualification hierarchy

Before exploring the role's practical application, we must understand the layered role structure in DGUV 209-093.

The standard defines three qualification levels:

Stufe 1: FuP (Fachkundig unterwiesene Person) — Electrically instructed person. Competent to work on HV systems under supervision. Requires 2 days of initial instruction and 1 day of annual refresher training. Cost-effective for workshop teams.

Stufe 2: Fachkraft (Skilled person for HV) — More extensive 5-day certification. Can conduct independent work and supervise FuP technicians. Required for team leads.

Stufe 3: Elektrofachkraft (Electrician) — Full HV certification. Designs systems and validates technical documentation.

For most production-line activities — battery module assembly, connector inspection, thermal testing — the FuP qualification is sufficient and legally compliant. This is the key insight that many workshop managers miss.

What a FuP can and cannot do: task authority under DGUV 209-093

Task authority hinges on three factors: the voltage level (HV only, not EHV), the task type, and the presence of a supervising Fachkraft.

FuP permitted tasks (under supervision)

• Assembly of pre-designed HV components

• Connector installation and verification

• Isolation and lock-out procedures (under instruction)

• Visual inspection of HV systems

• Basic troubleshooting (fault identification, not repair design)

FuP prohibited tasks

• Work on extra-high voltage (EHV > 1000V DC) systems

• Design or modification of HV circuits

• Unsupervised work (always requires Fachkraft present or available)

• Testing and validation of HV systems beyond simple continuity checks

• Authorization of repairs or modifications

The critical phrase is "under supervision." A Fachkraft does not need to observe every action, but must be available and responsible for the FuP's work. This distinction is often misinterpreted.

Supervision mechanisms and practical implementation

Effective supervision under DGUV 209-093 requires three structural elements:

Competence-based delegation

The Fachkraft must explicitly document which tasks the FuP is competent to perform. This is not a blanket authorization—it's task-specific. Example: "FuP may assemble battery modules in Assembly Line 3, per standard procedure BM-001."

Technical oversight

The Fachkraft must conduct regular spot checks or be accessible for immediate consultation. On a production line with 20 FuP technicians, the supervising Fachkraft typically monitors progress, reviews completed work, and resolves non-standard situations.

Documented training records

Each FuP must have:

• Certificate of completion from an accredited training provider

• Signed competency attestation from the supervising Fachkraft

• Annual refresher training attendance record

These records are inspected during regulatory audits. Lack of documentation can result in severe penalties, even if the technical work itself was sound.

Why manufacturers choose FuP: cost-benefit analysis

The economics are straightforward:

FuP training costs approximately €400–600 per technician (2 days + 1 day annual refresh). Fachkraft certification costs €2,000–3,500 per person (5 days). For a workshop with 50 assembly technicians and 1-2 supervisors, the FuP model reduces certification spend by 85% compared to making everyone a Fachkraft.

Beyond cost, FuP deployment accelerates time-to-productivity. A new production line can be staffed and operational within weeks, not months. For Chinese OEMs expanding into Europe, this is a competitive advantage.

Common compliance pitfalls to avoid

In our consulting work with European HV workshops, we've identified five recurring mistakes:

1. Assuming "under supervision" means constant observation. It doesn't. A Fachkraft can supervise multiple FuP technicians if the work is standardized and low-risk.

2. Missing or expired training certificates. Annual refresher training is mandatory, not optional. Regulators view lapses as non-compliance.

3. Assigning tasks beyond FuP authority without documented supervisor approval. If a FuP is asked to troubleshoot a design flaw, that requires Fachkraft involvement and documentation.

4. No supervision structure defined. Workshops sometimes hire Fachkraft staff but don't formalize their supervisory role. This creates ambiguity and liability.

5. Confusing FuP with unskilled labor. FuP is a distinct legal role, not a shortcut. It's for people with foundational electrical knowledge who have completed formal instruction.

Next steps: implementing FuP in your workshop

If you're establishing a European HV workshop, here's the implementation sequence:

• Define task categories. Break down your production workflow into tasks suitable for FuP vs. Fachkraft.

• Hire accredited training provider. Select a provider certified under DGUV 209-093 to deliver FuP instruction. (E-Safe Consulting can recommend providers in your region.)

• Designate supervising Fachkraft(e). Hire or develop internal Fachkraft staff. Define their supervision scope.

• Document delegation. Create written procedures for each FuP-authorized task, signed by the Fachkraft.

• Schedule and track refresher training. Plan annual 1-day refresher sessions 2-3 months before certification expires.

• Audit and update. Conduct an annual compliance review to ensure documentation and procedures stay current.

E-Safe Consulting specializes in regulatory compliance for European HV operations. We help manufacturers audit their current structure, identify gaps, and implement FuP programs that reduce costs without compromising safety or legal standing.

Conclusion: FuP is strategic, not a shortcut

The FuP role under DGUV 209-093 is not a way to cut corners. It's a precisely defined qualification level that balances regulatory compliance, cost efficiency, and safety. For Chinese EV manufacturers establishing European operations, understanding and correctly implementing the FuP role is essential.

Done right, the FuP model reduces training costs by 85%, accelerates deployment, and maintains full compliance. Done wrong—by ignoring supervision requirements or missing refresher training—it creates massive liability.
