Product questions
What to confirm before selection
What is the published reference for ML-APC400?
The page lists the catalogue reference configuration for ML-APC400. Final ratings and interfaces remain subject to the approved project documents.
Are the published dimensions fixed for every project?
No. The dimensions are a documented reference envelope. Final width, depth, height and lineup arrangement depend on the selected devices, ratings, cable interfaces and approved general arrangement.
What evidence can be requested?
Test and conformity evidence available can be reviewed for applicability to the offered model and configuration. Project-specific routine verification is handled separately during manufacturing and release.
