1.1GENERAL
The Mitsubishi 2033D 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 2033D Series UPS is available in three (3) kVA sizes-30, 50 and 80kVA, and also in two (2) output voltages - 208V and 480V. Specifications for each kVA and voltage model appear in Section 1.4. 30kVA model have batteries included in the UPS module cabinet. 50 and 80kVA models have external batteries. The principles of operation described herein are applicable to all models.
This manual provides an overview of the 2033D 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.

1.3Overview
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.
Figure 1.3 shows the path for battery operation, with the load supplied from the inverter.

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 AC Bypass Input circuit breaker (MCCB) for protection of the UPS and cables are field supplied and field installed. (See WARNING 2 on page 1-2)

Referring to Figure 1.2, the Internal Static Bypass line is a Hard wired line through Static Transfer Switch 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 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: In the event of AC input source failure or interruption, the converter will de-energize and the 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 converter 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, the converter 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.
