ACS550 Altitude Derating Guide

This document provides engineering guidance on derating the ACS550 drive for installations above 6600 feet, specifically addressing a 50HP 460V 65A motor at 10,000 feet. It explains that while standard derating applies up to 6600 feet, a 20% derating (1% per 330 feet above 3300 feet) is recommended for higher altitudes, and confirms safety clearance compliance for corner grounded networks at 10,000 feet.
