MITSUBISHI ELECTRIC 2033C SERIES UPS OWNERS / TECHNICAL MANUAL Page Number: 1-3 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.

MITSUBISHI ELECTRIC 2033C SERIES UPS OWNERS / TECHNICAL MANUAL Page Number: 1-4 1.2 Definitions UNINTERRUPTIBLE POWER SUPPLY SYSTEM (UPS) - All components within the UPS Module Cabinet and associated batteries which function as a system to provide continuous, conditioned AC power to a load. This is sometimes referred to as the "System".

MITSUBISHI ELECTRIC Page Number: 1-5 2033C SERIES UPS OWNERS / TECHNICAL MANUAL 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 1.1 Single Line Diagram - Normal Operation. Load powered by inverter.

MITSUBISHI ELECTRIC 2033C SERIES UPS OWNERS / TECHNICAL MANUAL Page Number: 1-8 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.
