"The structural civil engineer or design engineer of record is responsible for detailing the equipment connection and anchorage requirements (including the lateral restraint system if appropriate) for the given installation. The installer and manufacturers of the anchorage and lateral restraint system are responsible for ensuring that the mounting requirements are met. Schneider Electric is not responsible for the specification and performance of these systems.
Each section must be anchored per detail supplied by the engineer of record to the load-bearing path of the building structural system."
