MITSUBISHI ELECTRIC 2033D SERIES UPS OWNERS / TECHNICAL MANUAL Page Number: 1-1 1.0 INTRODUCTION Your Mitsubishi Uninterruptible Power Supply System (UPS) is designed to provide many years of reliable protection from power failure, brownouts, line noise, and voltage transients. To ensure optimum performance of the equipment, follow the manufacturer's instructions. This manual contains descriptions required to operate the UPS. Please read this manual carefully and retain it for future reference.
2033D SERIES UPS OWNERS / TECHNICAL MANUAL MITSUBISHI ELECTRIC Page Number: 1-2 WARNING 2 This UPS does not include a Bypass input circuit breaker (MCCB) to protect bypass circuit. Bypass input circuit breaker (MCCB) are to be field supplied and installed.
2033D SERIES UPS OWNERS / TECHNICAL MANUAL MITSUBISHI ELECTRIC Page Number: 1-3 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.
MITSUBISHI ELECTRIC 2033D 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 that function as a system to provide continuous, conditioned AC power to a load. This is sometimes referred to as the "System".
Page Number: 1-5 2033D SERIES UPS OWNERS / TECHNICAL MANUAL MITSUBISHI ELECTRIC 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. A) Normal Operation. FIGURE 1.
