1.2 GENERAL

The MITSUBISHI M9950 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 M9950 SERIES UPS is available in five kVA sizes – 60, 120,160, 200, 300, 400, 500
and 600kVA. Specifications for each kVA model appear in Section 1.6. The principles of
operation described herein are applicable to all models.
This manual provides an overview of the M9950 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.
