System role

This section explains what the product does and where it acts in the surrounding system.

Function
Routes a test connection for protective modular-case components.
System position
In the protective-case test path, the module sits between the case test points and the protection equipment under test.
Upstream / inputs
The protective case test points provide the upstream test connection.
Downstream / outputs
The protection equipment receives the downstream test-path connection.
Limitations
Unknown: installation fit, revision, condition and current availability require separate confirmation.

Evidence ledger

Facts, inferences, and unknowns are kept separate.

Facts

  • The captured Siemens data sheet identifies 7XG2220-2AA00-0AA0 as an ancillary test module for protective modular-case components.

    Confidence: medium

  • The data sheet specifies no open-circuit facility between terminals 13 and 14 when the cover is removed, with size E2 and vertical mounting.

    Confidence: medium

Inferences

  • In the protective-case test path, the module sits between the case test points and the protection equipment under test.

    Confidence: medium

    Rationale: The captured product function and system context establish the stated placement within the described system.

Unknowns

  • Unknown: installation fit, revision, condition and current availability require separate confirmation.

    Confidence: low

    Missing evidence: The captured exact-reference sources do not establish a site-specific replacement decision.

Recipient and data disclosure

Named recipient: Ardkor human-qualification queue (internal local preview). No partner delivery is enabled here.

Data retained for this review: reference, selected route, location, technical context, contact details, consent state, and any accepted private attachment.

Response expectation: none is promised. If external routing is enabled later, the partner name, disclosed fields, and response expectation must be shown and accepted again.

Withdrawal and deletion: use the private request controls from the receipt to withdraw further processing or request access/deletion. The request remains recorded until the relevant Ardkor systems and any recipient confirm completion.

Read the privacy information before sending. For corrections, access, or deletion help, use the contact page or email reference@ardkor.org; mailbox delivery and attendance have not been verified.

This routing state is separate from watch, marketing, payment, and analytics choices. If no capable service match is found, the request remains a human-qualification lead and is never presented as provider acceptance.
