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.

1.3 Overview
The UPS provides two power paths between the utility source and the critical load.
Figure 1.1 shows the path for normal operation, with the load powered from the inverter.
Figure 1.2 shows the path for bypass operation, with the load supplied through the static
bypass line.
A) Normal operation: Load power supplied by each system UPS inverter.

During normal operation, the path through the UPS inverters is used to power the load.
Referring to Figure 1.1: For each system UPS, the Input AC power is converted to DC by
the Rectifier. DC power is utilized to charge the UPS battery and to provide power to the
Inverter. The Inverter converts the 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 load.
The power drawn by the critical load is equally shared between all system UPS.
In the event of a UPS module failure, the critical load power will be continually supplied
and shared by all other system UPS.
In the event of a load overcurrent, all system UPS will transfer to bypass without
interruption to the critical load.

Referring to Figure 1.2: The Internal Static Bypass line is a Hard wired line through CB3
and contactor 52S which supplies the critical load with unconditioned input power.
Each system UPS internal static bypass line will equally share the power supplied to the
critical load.
The internal static bypass line will route power to the critical load while the UPS module is
de-energized during Start-up and before the system is fully operational.
Bypass operation will occur In the event of a load overcurrent, with all system UPS
transferring to bypass without interruption to the critical load.
The internal control system determines the operation of the two paths, with the load
powered from the inverter being the normal operation.

Referring to Figure 1.3: In the event of AC input source failure or interruption, each
system UPS rectifier will de-energize and each UPS battery will immediately discharge
and supply DC power to the Inverter to maintain continuous AC power to the load. This
operation will continue until:
a) The battery capacity expires and the inverter turns off, or
b) Input power is restored after which the rectifier will power the inverter and critical load
and simultaneously recharge the batteries.
A fully charged battery will provide power for the specified time at the rated load, or longer,
at a reduced load.
When power is restored after a low battery shutdown, each system UPS Rectifier
automatically restarts operation, recharges the batteries and the Inverter is automatically
restarted without operator intervention. Load is automatically assumed by the inverter
without operator intervention.
The power drawn by the load is equally shared between all system UPS during battery
operation.
