APC by Schneider Electric ACAC10003 InRow Roof Height Adapter
Overview
The ACAC10003 is a rack roof height adapter designed to bridge the physical gap when converting an SX42U rack enclosure to a VX42U configuration in APC InRow cooling deployments. If you're migrating or extending an InRow RC cooling row and the rack heights don't match at the roofline, this adapter closes that gap mechanically — preventing air bypass at the top of the assembly that would otherwise compromise the closed-loop cooling path. At 23.6 x 42.1 x 2.95 in (600 x 1070 x 75 mm) and 15 lbs, it fits between the rack roof panel and the InRow unit without structural improvisation.
Compatibility
The ACAC10003 is specifically designed for use with the following APC systems:
- APC InfraStruXure InRow RC: the primary target deployment — row-based cooling where rack-to-unit height alignment is required for proper airflow containment.
- APC Close Coupled Air Conditioners: applicable where close-coupled cooling units are paired with APC rack enclosures in the SX42U-to-VX42U transition scenario.
This adapter addresses the specific SX42U to VX42U height delta. It is not a universal rack adapter — confirm your source and target rack U-heights match this conversion before ordering. If your deployment uses a different rack height pairing, verify compatibility against APC InRow accessory documentation for your specific enclosure series.
Installation Notes
Mounting is rack-based and integrates at the roof junction between the enclosure and InRow cooling unit. The 75 mm (2.95 in) depth represents the height differential this adapter spans — verify clearance above the rack row before installation, particularly in low-ceiling raised-floor environments or under cable trays. No specific torque specs or tooling data are present in available evidence; follow APC InRow installation guides for fastener requirements applicable to your enclosure revision.
