2033A SERIES UPS OWNERS / TECHNICAL MANUAL MITSUBISHI ELECTRIC 1.0 Page Number: 1-1 INTRODUCTION The Mitsubishi Uninterruptible Power Supply (UPS) is designed to provide many years of reliable power supply and protection from power failure, brown-outs, line noise and voltage transients. To ensure optimum performance of the equipment, follow the manufacturer's instructions accordingly. This manual contains descriptions for the installation and operation procedures of the UPS.
2033A SERIES UPS OWNERS / TECHNICAL MANUAL MITSUBISHI ELECTRIC Page Number: 1-2 1.1 SAFETY PRECAUTIONS The safety precautions are categorized as DANGER and CAUTION in this manual. DANGER : A dangerous situation may occur if improperly handled, leading to severe or fatal injuries. CAUTION: A dangerous situation may occur if improperly handled, leading to minor serious injuries. Note that some items described as CAUTION may lead to severe results depending on the situation.
MITSUBISHI ELECTRIC 2033A SERIES UPS OWNERS / TECHNICAL MANUAL Page Number: 1-3 CAUTION PRECAUTIONS FOR INSTALLATION Do not block the intake/exhaust ports. -If the intake/exhaust ports are blocked, the internal temperature of the UPS will rise and could lead to fires from battery electrolyte leakage, fire ignition or part deterioration. Follow the UPS instruction manual carefully when installing the unit. -Improper installation could lead to injury such as the UPS falling over, etc.
2033A SERIES UPS OWNERS / TECHNICAL MANUAL MITSUBISHI ELECTRIC Page Number: 1-4 CAUTION PRECAUTIONS FOR MAINTENANCE AND INSPECTION The inside of the UPS must be inspected or repaired only by qualified personnel. -Failure to observe this could lead to electrical shocks, injuries, burns, smoke generation or fires. Periodically replace the battery. -Batteries that have exceeded the replacement life could lead to fires from electrolyte leakage or fire ignition.
MITSUBISHI ELECTRIC 2033A SERIES UPS OWNERS / TECHNICAL MANUAL Page Number: 1-5 APPLICATION This UPS shall NOT be applied to support equipment (*) that could affect the human lives. Special considerations are required when applying this UPS to the equipment (**) that affect human safety and/or maintain public services. Be sure to contact/inform MITSUBISHI if it is such a case. The application without special consideration may cause serious accidents.
2033A SERIES UPS OWNERS / TECHNICAL MANUAL MITSUBISHI ELECTRIC WARNING Page Number: 1-6 3 The UPS is to be installed in a controlled environment. Improper storage and installation environment may deteriorate insulation, shorten component life and cause malfunctions. Keep the installation environment per standard described as follows: UPS Installation Environment TABLE 1.1 No.
2033A SERIES UPS OWNERS / TECHNICAL MANUAL MITSUBISHI ELECTRIC WARNING Page Number: 1-7 4 This UPS does not include a Bypass Input circuit breaker (MCCB). The Bypass Input contactor (CB3) does not protect against load induced short circuits. The bypass input circuit breaker (MCCB) is field supplied and installed. When Bypass Input is fed by an input transformer the requirement for Bypass Input circuit breaker can be met with circuit breaker (MCCB) on the primary side of the transformer.
MITSUBISHI ELECTRIC 1.2 2033A SERIES UPS OWNERS / TECHNICAL MANUAL Page Number: 1-8 GENERAL The Mitsubishi 2033A 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, back up power from the UPS battery permits the orderly shutdown of equipment supported by the UPS.
MITSUBISHI ELECTRIC 1.3 2033A SERIES UPS OWNERS / TECHNICAL MANUAL Page Number: 1-9 DEFINITIONS UNINTERRUPTIBLE POWER SUPPLY SYSTEM (UPS) - All components within the UPS Module Cabinet includes the batteries which function as a system to provide continuous, conditioned AC power to a load. This is sometimes referred to as the "System".
2033A SERIES UPS OWNERS / TECHNICAL MANUAL MITSUBISHI ELECTRIC 1.4 Page Number: 1-10 OPERATION OVERVIEW The UPS provides two power paths between the utility source and the critical load as shown in Figures 1.1 and 1.2. FIGURE 1.1 Single Line Diagram - Normal Operation. Load powered through inverter.
2033A SERIES UPS OWNERS / TECHNICAL MANUAL MITSUBISHI ELECTRIC Page Number: 1-11 FIGURE 1.2 Single Line Diagram - Internal Bypass. Load fed through static bypass line.
2033A SERIES UPS OWNERS / TECHNICAL MANUAL MITSUBISHI ELECTRIC Page Number: 1-12 FIGURE 1.
MITSUBISHI ELECTRIC 2033A SERIES UPS OWNERS / TECHNICAL MANUAL Page Number: 1-13 The rotary maintenance bypass switch is identified as 52CS in Figure 1.4. 52CS is a two position make-before-break transfer switch. 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.
