1.0 GENERAL
The Mitsubishi 9700 Series UPS is designed to provide continuous, clean electrical power to your critical load and to monitor power conditions affecting that 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 9700 Series UPS is available in five kVA sizes-100, 150, 225, 300, 375kVA. Specifications for each kVA model appear in Section 1.3. The principles of operation described herein are applic able to all models.
This manual provides an overview of the 9700 Series components and their functions. It describes the appearance and purpose of operator controls and indicators. It contains procedures for operation, start - up, shut dow n, and basic maintenance.

1.1 Definitions
UNINTERRUPTIBLE P OWER SUPPL Y SYSTEM (UPS) - All components within the UPS
Module Cabinet includes the batteries which function as a system to provide continuous, conditioned AC power to a load. This is sometimes referred to as the "Sy s t em".
UPS MODULE CABINET - The metal enclosure which contains the Converter / Charger, the Inverter, the Static Transfer Switch, the Internal Bypass line, the operator controls, and the internal control syste m requ ired t o provide specified AC power to a load.
UPS MODULE - The Converter / Charger and Inverter assemblies which, under the direction of the internal control system and operator controls, provide specified AC power to a load.
CONVERTER / CHARGER - The UPS components which contain the equipment and controls necessary to convert input AC power to regulated DC power required for battery charging and for supplying power t o t he I nverter.
INVERTER - The UPS components which contain the equipment and controls necessary to convert DC power from the Converter / Charger, or the battery, to AC power required by the critical load.
STATIC TRANSFER SWITCH - The device which connects the critical load to the bypass line when the UPS mo dule cannot supply continuous power.
BYPASS LINE - The line which conducts electricity directly from the input power source to the critical load during Maintenance or whenever the UPS is not completely operational.
INPUT POWER - Power provided by the electrical utility company, or auxiliary generator, which is connected to t he UPS for supplying the critical load.

1.2 Overview
The UPS provides two power paths between the utility source and the critical load as shown in figures 1.1 and 1.2.

When the load is on the Inverter, the internal control system determines which of the two paths supplies power to the load. During normal operation, the path through the UPS module is used.
Input AC power flows through the UPS where it is converted to DC by the Converter / Charger. This DC power is utilized to charge the UPS battery and to provide power to the Inverter. The Inverter converts t he DC power to clean AC power to supply the critical load.
The conversion - inversion process eliminates any voltage transients or fluctuations existing in the input power before it reaches the critical lo ad.
* The Bypass Input circuit breaker (MCCB) for protection of the UPS and cables is field supplied and field inst al led. (See WARNING 2 on page iv)

B) Internal Static Bypass Li ne (FI GURE 1.2)
The Internal Static Bypass line is a Hard wired line through CB3, contactor 52S which supplies the critical load with unconditioned input power. The purpose of this line is to route power to the critical load while the UPS module is de-energized during Start-up before the system is fully operat ional.

If the input power is int er r upt ed, the battery will i m mediately supply t he DC power required by the Inverter to maintain continuous AC power to the load. A fully charged battery will provide power for the specified ti me at t he rat ed load, or longer, at a reduced load.

When power is restored after a low battery shutdown, the Converter automatically restarts operation, recharges the batteries, and the Inverter is automatically restarted without operator intervention. The load is assumed by the inverter automatically without operator intervention.
In the event of a power failure, the rectifier will de-energize and the batteries will discharge into the inverter and maintain power to the critical until a) the battery capacity expires and the inverter turns off, or b) input power is restored after which the converter will power the critical load and simultaneously recharge the batteries. Figure 1.3 illustrates the flow diagram during battery operation.
