GENERAL
The Mitsubishi 2033C Series UPS is designed to provide continuous and clean electrical
power to a critical 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, backup 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 2033C Series UPS is available in seven (7) kVA sizes: 7.5, 10, 15, 20, 30, 40 and
50kVA. Specifications for each kVA model appear in Section 1.5. Models up to 30kVA have
batteries included in the UPS module cabinet. 40kVA and 50kVA models have external
batteries. The principles of operation described herein are applicable to all models.
This manual provides an overview of the 2033C Series components and their functions.

OPERATION 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.

During normal operation, the path through the inverter is used to power the load.
Referring to Figure 1.1: Input AC power is converted to DC by the Converter. 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 Input circuit breaker(MCCB) for protection of the UPS and cables are field supplied and
field installed. (See WARNING 4 in section 1.1).

Referring to Figure 1.2, the Internal Static Bypass line is a Hard wired line through CB3 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 (converter and inverter), and
during Start-up before the system is fully operational.
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, if the input power is interrupted, the battery will immediately supply the
DC power required by the Inverter to maintain continuous AC power to the load. A fully charged
battery will provide power for the specified time at the rated load, or longer at 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 Converter will de-energize and the batteries will discharge
into the Inverter and maintain power to the critical load until a) the battery capacity expires and
the inverter turns off, or b) input power is restored after which the converter will power the
inverter and simultaneously recharge the batteries. Figure 1.3 illustrates the flow diagram during
battery operation.
