1.1 GENERAL
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.

1.3 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.
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.

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.

3.4 Operating Procedures
A) UPS Start-up Procedure
1. Close External Input Circuit Breaker(User supplied. Refer to warning 2).
2. The “LOAD ON BYPASS.” LED turns on and power is supplied to the critical load
from the static bypass line automatically.
3. Within ten (10) seconds, the “INV.OP.” LED flashes and the Inverter starts. The UPS
will automatically transfer the load from the static bypass line to the inverter and the
“INV.OP.” light turns on.
B) UPS Shutdown Procedure
1. If a total UPS shutdown is required, press the "STOP" button on the front panel. With
in 3 seconds the “BYP.OP.” LED will turn on and the UPS will transfer the load to the
static bypass line.
WARNING
: Verify the load is OFF if the next step is to be performed.
NOTE : Power to the critical load is supplied through the static bypass line.
Power to the critical load will be lost after execution of the next step.
The load will drop.
2. If turning off all power to the critical load is desired, open the AC Input Circuit Breaker
(User supplied.).
WARNING :
In the bypass mode, all UPS power terminals are still live.
Lethal voltages are present. De-energize all external
sources of AC and DC power before handling UPS
C) EPO (Emergency Power Off) Procedure
If all power supply shutdown is required in emergency, press the "EOP" button on the
front panel. The UPS would be shutdown and the load will not be supplied.
WARNING
: When remote EPO, it is necessary to open the input circuit
.
breaker, which is user supplied.

3.5 Maintenance bypass set-up procedures
CAUTION: 1. The following instructions are for single operation ONLY.
2. To avoid parallel operation between a bypass source of one module and an
inverter source of another module, which may result large cross current
between the two modules,
DO NOT OPERATE THE MAINTENANCE
BYPASS SWITCH UNDER PARALLEL OPERATION (Must be kept
in NORMAL position).
Page Number:
A) Transfer of load from inverter to maintenance bypass
1. Stop the inverter by pressing the START/STOP key on the LCD’s Main Menu (see
Figure 2.3). Simultaneously press the two (2) STOP keys per the instructions. (Note :
inverter STOP function inhibited if bypass and inverter are out of sync.)
2. Confirm via the flow diagram on the LCD that the load is fed from the UPS’ static
bypass line. Also confirm that the “BYP.OP.” LED is on (No.3 LED on Figure 2.1)
3. After confirming Step2, rotate MBS (52CS) clockwise to the “TRANSFER” position
(see figure 1.4 for the location of 52CS). The MBP Lamp (No.7 Lamp on Figure 2.1)
will be illuminated. (Do not rotate MBS (52CS) if the load is NOT
fed by bypass
source).
4. After 3 seconds, rotate 52CS clockwise to the “BYPASS” position.
5. UPS can now be powered down.
6. Transfer complete. Load is fed from the external source (Utility or generator).
B) Transfer of load from maintenance bypass to inverter
1. Confirm that the Static Bypass line is on and energized.
2. Rotate 52CS counterclockwise from the “BYPASS” position to the “TRANSFER”
position, wait 5 seconds.
3. On the UPS, confirm the “BYP.OP.” LED is on. If not, press the “STOP” button.
4. Rotate 52CS counterclockwise to the “NORMAL” position.
5. Close the external input breaker. Confirm that the converter operates and DC
contactor 72B closes.
6. Press “START” button on the LCD panel to transfer the load to inverter source. The
“INV.OP.” LED will be illuminated.
7. Transfer complete. Load now powered by the inverter.
