How to use

Position the NetShelter on a level surface and, if required, secure leveling feet or castors per site needs. Install the vertical mounting rails to the desired U positions using the captive hardware and align them with the numbered U markings. Route power and data cabling through the roof or bottom cable access openings with pre-installed brushes to maintain airflow and containment. Mount PDUs, patch panels and equipment on the 19" rails and secure doors and side panels using the integrated key lock for physical security. Refer to the enclosure user documentation for eyebolt lifting requirements, weight limits and seismic mounting instructions.

Recommendations

For optimal thermal performance and cable organization, use perforated doors for front-to-rear airflow, install vertical cable organizers alongside equipment mounting rails, and follow the manufacturer’s grounding guidance. Check compatibility of accessory modules and PDUs with Schneider Electric’s configurator before final assembly.
