1.1GENERAL

The Mitsubishi 2033D Series UPS is designed to provide continuous and clean electrical power to a critical load. Additionally the UPS monitors power conditions affecting the load. In the event of an input power failure, the UPS will supply power to the critical load for the specified battery time.

If the input power is not restored promptly, back up power from the UPS battery permits the orderly shutdown of equipment supported by the UPS. The UPS is simple to start-up, operate and maintain.

The 2033D Series UPS is available in three (3) kVA sizes-30, 50 and 80kVA, and also in two (2) output voltages - 208V and 480V. Specifications for each kVA and voltage model appear in Section 1.4. 30kVA model have batteries included in the UPS module cabinet. 50 and 80kVA models have external batteries. The principles of operation described herein are applicable to all models.

This manual provides an overview of the 2033D Series components and their functions. The appearance and purpose of operator controls and indicators is described with procedures for operation, start-up, shutdown and basic maintenance included.
