About This Manual OVERVIEW This manual is intended for users of the HA3000 20-80 kVA series Uninterruptible Power System (UPS). It provides a general introduction to the UPS and available options, and detailed information on system controls and operation. WARNING This unit contains no user-serviceable parts. Only the key-locked doors should be opened to gain access to the circuit breakers. No other doors should be opened or covers removed, for any reason, by untrained personnel.
viii About This Manual The manual covers the following topics: • Chapter 1 provides a general system description of the HA32A UPS and a description of the options available for use with the HA32A UPS. • Chapter 2 provides detailed information on the operation of the system status and control panel, the electromechanical and programmable controls, the UPS monitor and available menus, the automatic and manual operating modes, and the alarm conditions and their causes.
Notes to the User The purpose of the HA3000 UPS is to provide short-term power outage protection for the critical load. The protection time will vary depending upon the size of the load, the charge condition of the batteries, the temperature, and the amount of battery time purchased. For extended power outages, operators wishing to initiate an orderly shutdown should be aware of the battery time available on their system.
1 HA3000 SERIES UPS INTRODUCTION 1.1 GENERAL This chapter introduces the HA3000 series of UPS products rated 20 to 80 kVA. It describes the UPS system, introduces controls and indicators, and describes available options. Figure 1–1 shows the HA32A UPS.
1–2 HA3000 SERIES UPS INTRODUCTION 1.2 SYSTEM DESCRIPTION The HA3000 series Uninterruptible Power System (UPS) is a three-phase on-line interface between a building’s utility power distribution system and the customer’s critical load. The UPS is designed to ensure a continuous flow of clean electrical power to critical loads by addressing common power problems associated with utility ac power. These problems include spikes, electrical noise, sags, brownouts, surges, dropouts, and frequency variations.
HA3000 SERIES UPS INTRODUCTION 1–3 The major components of the HA32A UPS include: • A rectifier/battery charger • A transistorized pulse-width modulated (PWM) static inverter • A continuous-duty rated static switch that automatically transfers the load to and from the bypass ac input source and the UPS inverter output • An internal manual bypass function comprised of three separate switches that allows the critical load to be operated from the utility source • A battery system housed in an externa
1–4 HA3000 SERIES UPS INTRODUCTION 1.2.1 Rectifier/Battery Charger The rectifier/battery charger consists of: • AC Input Circuit Breaker (Q1): The ac input circuit breaker provides mechanical isolation and electrical protection for the input of the UPS. • Input Autotransformer: The input autotransformer is used to match the external ac input source to that required internally for the UPS.
HA3000 SERIES UPS INTRODUCTION 1–5 The three internal manual bypass nonautomatic switches are designated as: • Bypass (MAINS2) Input (Q4S) • UPS Output Isolation (Q5N) • Manual Bypass (Q3BP) For startup or shutdown of the equipment, correct operation of the three switches is shown on the liquid-crystal display (LCD), which is located on the system status and control panel (SS&CP).
1–6 HA3000 SERIES UPS INTRODUCTION 1.3 PROGRAMMABLE CONTROLS AND INDICATORS All HA32A programmable controls (excluding circuit breakers and nonautomatic switches) and indicators are located on the system status and control panel (SS&CP), which is shown in Figure 1–4.
HA3000 SERIES UPS INTRODUCTION 1–7 1.4 BATTERY CABINET Each HA32A UPS requires a separate HA32B UPS Battery Cabinet, which contains batteries having sufficient ampere-hour (A h) capacity to support the UPS and its intended load for the protection time specified. The UPS Battery Cabinet features sealed, maintenance-free, recombination type batteries. The batteries are maintenance-free because they do not require that the electrolyte level or the density of the electrolyte be checked periodically.
1–8 HA3000 SERIES UPS INTRODUCTION transformer secondary voltage is 208 Vac. The transformer supplies both the main ac input (MAINS1), and through the mechanical contactor, the bypass ac input (MAINS2). The transformer also provides complete electrical isolation between the utility line and the input of the UPS (rectifier/battery charger and battery). It also provides extra protection against electrical noise and ground faults.
HA3000 SERIES UPS INTRODUCTION 1–9 1.5.6 DC Ground Fault Detector The HA320-C2 DC Ground Fault Detector is used to detect current flowing from the battery terminals to ground. When a dc ground fault is detected, The UPS main ac input (MAINS1) circuit breaker (Q1) trips, shutting off the rectifier/battery charger, and initiates On Battery operation, which prevents any cascading failures. This fault is indicated by an "ENVIRONMENTAL FAULT" message on the UPS LCD display.

HA32A UPS OPERATION 2–29 2.5 OPERATING MODES The HA32A UPS has both automatic and manual operating modes. These modes of operation are described in more detail in the following sections. 2.5.1 Automatic Operating Sequences The four automatic operating sequences are described in the following sections. 2.5.1.1 Normal Operation Normal operation is when main ac input (MAINS1) power and bypass ac input (MAINS2) power are available and are within the prescribed tolerances.
2–30 HA32A UPS OPERATION 2.5.1.2 On Battery Operation On battery operation occurs when main ac input (MAINS1) power is lost, if the main ac input (MAINS1) power drops more than 15% below nominal value, or if the rectifier/battery charger circuit fails. The flow of power during on battery operation is shown in Figure 2–6.
HA32A UPS OPERATION 2–31 2.5.1.3 Input Power Restored/Battery Charging As soon as main ac input (MAINS1) power is restored, and the voltage and frequency are within specified tolerances, the UPS returns to normal operation (see Section 2.5.1.1). If the battery reaches its end point of discharge before the main ac input (MAINS1) power is restored, the UPS inverter will shut down and must be manually restarted by following the START-UP menu in Section 2.4.1.
2–32 HA32A UPS OPERATION In the event of a major overload (inrush condition) on the output of the UPS inverter, an immediate transfer of the load to the bypass ac input (MAINS2) power source takes place. The load is automatically returned to the UPS inverter output without interruption when the inrush condition is over. This operating mode allows startup of load devices demanding short-term, high inrush currents, provided that the UPS inverter is synchronized to the bypass ac input (MAINS2) power source.
HA32A UPS OPERATION 2–33 2.5.2.3 UPS Manual Bypass This sequence is used to manually transfer the load to the bypass ac input (MAINS2) power source to bypass the UPS circuits. This sequence should be initiated when problems with the rectifier/battery charger or static switch present the possibility of dropping power to the critical load. This operational sequence can be initiated by following the instructions in the Main Menu, item BYPASS PROCEDURE (see Section 2.4.5).
2–34 HA32A UPS OPERATION 2.6 ALARMS There are two types of alarms in the HA32A UPS; minor and major alarms.
