INTRODUCTION AND SYSTEM DESCRIPTION Congratulations on your choice of the Liebert 2U POD™. The Liebert 2U POD provides maintenance bypass capability as well as power output distribution. The Liebert 2U POD can be used on UPSs in the rack mount or tower configuration. The Liebert 2U POD provides an isolated path of power for your UPS system for preventive maintenance or service. System Description The 2U POD has two modes of operation: UPS (UPS available) and MAINS (maintenance bypass).
