1.1 GENERAL

The Mitsubishi 9800A 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 9800A SERIES UPS is available in seven kVA sizes-100, 150, 225, 300, 375, 500 and 750kVA. Specifications for each kVA model appear in Section 1.4. The principles of operation described herein are applicable to all models.

This manual provides an overview of the 9800A 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.
