1.1 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 1.4. 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. The appearance and purpose of operator controls and indicators is described with procedures for operation, start-up, shutdowjn 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.

UPS Module

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 2 in section 1.0).

UPS Module

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.

The two positions are identified as NORMAL and BYPASS. In the NORMAL position the load is fed by the UPS - either through the inverter or through the static bypass line. In the BYPASS position the load is powered by an external source such as the utility or a generator. This transfer operation must be made while the UPS is in the static bypass mode.

The transfer procedure to place the UPS in maintenance bypass mode, or from bypass mode to normal operation mode is outlined below:

A) Transfer of load from inverter to maintenance bypass

1. On the front panel, press the "STOP" button. The “BYP.OP.” LED illuminates within 3 seconds.

2. After confirming that the “BYP.OP.” LED is illuminated, Rotate MBS(52CS/SWM) clockwise to the “TRANSFER” position (Do not rotate 52CS/SWM if the “BYP.OP.” LED is NOT illuminated).

3. After 3 seconds, rotate 52CS/SWM clockwise to the “BYPASS” position.

4. Transfer complete. Load is now powered from the external source. UPS can be shutdown.

B) Transfer of load from maintenance bypass to inverter

1. Rotate 52CS/SWM counterclockwise from the “BYPASS” position to the “TRANSFER” position, wait 5 seconds.

2. On the UPS, confirm the “BYP.OP.” LED is illuminated. If not, press the “STOP” button.

3. Rotate 52CS/SWM counterclockwise to the “NORMAL” position.

4. On the UPS, press the “START” button. The “INV.OP.” LED should illuminate.

5. Transfer complete. Load now powered by the inverter.
